Graph management

tlp.newGraph()

Creates and returns a new empty graph.

Return type:tlp.Graph
tlp.loadGraph(filename[, graph = None])

Loads a graph in the TLP format from a file (extension can be .tlp or .tlp.gz). Returns the graph (a new graph if none is provided) or None if the import fails.

Parameters:
  • filename (string) – the path to the tlp file
  • graph – if provided, import new graph elements in that already existing graph
Return type:

tlp.Graph

tlp.loadGraph(fileName)

Loads a graph serialized in a file trough the available Tulip import plugins.

Since Tulip 4.8, the selection of the import plugin is based on the provided filename extension. The import will fail if the selected import plugin is not loaded. The graph file formats that can currently be imported are : TLP (.tlp or .tlp.gz), TLP Binary (.tlpb or .tlpb.gz), TLP JSON (.json), Gephi (.gexf), Pajek (.net, .paj), GML (.gml), Graphviz (.dot) and UCINET (.txt).

Before Tulip 4.8 and as a fallback, the function uses the “TLP Import” import plugin (always loaded as it is linked into the tulip-core library).

Returns a new graph or None if the import fails.

Parameters:filename (string) – the path to the file in one of the supported formats to parse.
Return type:tlp.Graph
tlp.saveGraph(graph, filename)

Serializes the corresponding graph and all its subgraphs (depending on the format) to a file through the available Tulip export plugins.

Since Tulip 4.8, the selection of the export plugin is based on the provided filename extension. The export will fail if the selected export plugin is not loaded. The file formats the graph can be exported to are : TLP (.tlp or .tlp.gz), TLP Binary (.tlpb or .tlpb.gz), TLP JSON (.json) and GML (.gml).

This function checks the file name for the ‘.gz’ extension and uses a compressed output if supported (TLP and TLP Binary only).

Before Tulip 4.8 and as a fallback, this function uses the “TLP Export” export plugin (always loaded as it is linked into the tulip-core library).

Returns whether the export was successfull or not.

Parameters:
  • graph (tlp.Graph) – the graph to export
  • filename (string) – the path to the destination file

If the color scale is a gradient, returned colors are interpolated in function of the position. If the color scale isn’t a gradient returned colors are the predefined colors steps.

The sample code below illustrates how to create and manipulate a color scale:

# Creating an empty color scale (default constructor creates a heatmap from blue to red).
colorScale = tlp.ColorScale([])

# Color scale initialization : from blue to red with gradient.
colorScale.setColorAtPos(0.0, tlp.Color(0,0,255))
colorScale.setColorAtPos(1.0, tlp.Color(255,0,0))

# The following syntax could also be used
# colors = [tlp.Color(0,0,255), tlp.Color(255,0,0)]
# colorScale.setColorScale(colors)
#    or
# colorScale = tlp.ColorScale(colors)

# Get the color for the position 0.5, i.e. Color(127,0,127).
color = colorScale.getColorAtPos(0.5);

# Reinitialize the color scale : from blue to red without gradient.
newColors = []
newColors.append(tlp.Color(0,0,255))
newColors.append(tlp.Color(255,0,0))
colorScale.setColorScale(newColors,False)

# Get the color for the position 0.3, i.e. Color(0,0,255).
color = colorScale.getColorAtPos(0.3)

# Get the color for the position 0.7, i.e. Color(255,0,0).
color = colorScale.getColorAtPos(0.7)
getColorAtPos(pos)

This method computes the color associated to a specific position in the color scale and returns it.

Parameters:pos (float) – This value defines the position of the color in the scale and must be between 0.0 and 1.0 (it will be clamped otherwise).
Return type:tlp.Color
getColorMap()

Returns a dictionary corresponding to the color scale.

Return type:a dictionary whose indexes are of type float and the values of type tlp.Color
isGradient()

Returns True if the color scale is a gradient.

Return type:boolean
setColorAtPos(pos, color)

This method adds a color to the color scale at a specific position.

Parameters:
  • pos (float) – the position in the color scale (0.0 <= pos <= 1.0)
  • color (tlp.Color) – the color to add at the specified position
setColorScale(colors[, gradient = True])

This method configures the color scale. If the scale was previously configured the old configuration is lost.

Parameters:
  • colors (list of tlp.Color) – The colors to use in the color scale.
  • gradient (boolean) – If set to True, the color scale is a gradient

tlp.StringCollection

tlp.DataSet

class tlp.DataSet

Deprecated since version 4.8: The direct use of that class is now deprecated as it is now mapped to a Python dictionnary for commodity of use (see Deprecation of direct use of the tlp.DataSet class).

This class is used to store a set of parameters to transmit to a Tulip algorithm. Below is an exhaustive list of data types that can be stored in a Tulip data set:

If you try to store an unsupported data type, an exception will be thrown. Each value stored in a data set is associated to a string key. Reading / Writing a value in a data set is done through the [] operator as illustrated below:

# data set creation
dataSet = tlp.DataSet()

# writing integer values
dataSet["height"] = 100
dataSet["width"] = 300

# reading integer values
area = dataSet["height"] * dataSet["width"] 

When reading a data set value, a reference is returned not a copy.

Parameters:key (string) – the key to check
Return type:boolean
getKeys()

Returns the list of keys associated to the values stored in the data set.

Tulip observation mechanism

tlp.Event

class tlp.Event

This class is the base one for representing an event in Tulip. Events are objects sent by objects whose classes derives from the tlp.Observable one. An event is characterized by its type. The base tlp.Event class only carries information as to the type of event, nothing specific :

  • tlp.Event.TLP_DELETE : send directly to all observers/listeners, not affected by tlp.Observable.holdObservers().
  • tlp.Event.TLP_MODIFICATION : sent to all observers/listeners. That type of event is first sent to observers then to listeners.
  • tlp.Event.TLP_INFORMATION : sent only to listeners.
  • tlp.Event.TLP_INVALID : never sent, used internally for delaying events.

Implement a class derived from tlp.Event to add custom events. Here is a sample code below:

class MyEvent(tlp.Event):

  # sender must be an instance deriving from tlp.Observable
  def __init__(self, sender, data):
    tlp.Event.__init__(self, sender, tlp.Event.TLP_MODIFICATION)
    self.data = data

  def getData(self):
    return self.data
sender()

Returns the object that sent the event.

Return type:tlp.Observable or one of its derived type.

tlp.Observable

class tlp.Observable

The tlp.Observable class is the base of Tulip’s observation system.

Each class that wishes to send or receive notifications needs to inherit from tlp.Observable.

Tulip has two separate mechanisms of observation : Observers and Listeners. These two mechanisms work through the same class, the difference lies in the way an Observer or Listener is attached to the object whose events it will receive.

The Listener is closer to the original pattern, where events are sent directly to the recipient. The Observer is a twist for performance purposes, it can receive the events in a delayed fashion, and cannot know if the event was just sent or was delayed.

The purpose of this twist is to allow algorithms that perform a high number of modifications (e.g. creating a grid to route edges, creating multiple subgraphs with metrics or layouts) to run smoothly without overcrowding the event queue. As events are sent for every graph modification (e.g. adding a node, deleting a node, setting a value on a node), the sheer quantity of events sent by these algortithms would cause a big performance hit.

This is avoided by using the static method tlp.Observable.holdObservers(). This holds all events in a queue and only sends them when the static method tlp.Observable.unholdObservers() is called.

The only exception to this mechanism is the tlp.Event.TLP_DELETE kind of event, that is never held back. Think of it as an unmaskable POSIX signal; whatever the connection to the object and the state of holdObserver, this event will get through. This is used to prevent crashes in the case where and object is listened or observed and is deleted, as it is likely the recipient keeps a pointer to the now deleted object.

The Listener however is not affected by the use of tlp.Observable.holdObservers() and tlp.Observable.unholdObservers().

The observables Observers and Listeners are internally stocked in a graph structure, allowing to visualize the connections easily. This eases debugging of observation-related bugs.

Events are always sent to Listeners first, and then to Observers, even when there is no hold.

To receive events, inherit from tlp.Observable, and implement one of two virtual functions.

To received events without delay, implement method tlp.Observable.treatEvent(). To attach to an object for receiving events, call its tlp.Observable.addListener() method.

To receive events after a delay, implement method tlp.Observable.treatEvents. To attach to an object for receiving events, call its tlp.Observable.addObserver() method.

addListener(listener)

Adds a Listener to this object. The Listener will receive events regardless of the state of tlp.Observable.holdObservers() and tlp.Observable.unholdObservers().

Parameters:listener (tlp.Observable) – The object that will receive events.
addObserver(observer)

Adds an Observer to this object. The Observer will receive events sent by this object, if there is no hold applied.

Parameters:observer (tlp.Observable) – The object that will receive events.
countListeners()

Gets the number of Listeners attached to this object.

Return type:integer
countObservers()

Gets the number of Observers attached to this object.

Return type:integer
getReceived()

Gets the number of received events.

Return type:integer
getSent()

Gets the number of sent events.

Return type:integer
hasOnlookers()

Returns whether there are Observers/Listeners attached to this object.

Return type:boolean
holdObservers()

Holds back all events until tlp.Observable.unholObservers() is called. Listeners are not affected by this function. Once this function is called, all events heading to an Observer will be held, except tlp.Event.TLP_DELETE events. The events are stored in a queue, and will be sent once tlp.Observable.unholObservers() is called. It is possible to nest calls to tlp.Observable.holObservers() and tlp.Observable.unholObservers(), and in this case the events will only be sent when there have been as many calls to tlp.Observable.unholObservers() as to tlp.Observable.holObservers(). It is possible to check whether the events are being help by checking the tlp.Observable.observersHoldCounter() function.

observersHoldCounter()

Static method to get the number of times tlp.Observable.holdObservers() has been called without a matching tlp.Observable.unholdObservers() call.

Return type:integer
removeListener(listener)

Removes a Listener from this object. The Listener will no longer receive events from this object.

Parameters:listener (tlp.Observable) – The Listener to remove from this object.
removeObserver(observer)

Removes an Observer from this object. The Observer will no longer receive events from this object.

Parameters:observer (tlp.Observable) – The Observer to remove from this object.
sendEvent(event)

Sends an event to all the Observers/Listeners.

Parameters:event (tlp.Event) – the event to send to the Listeners/Observers.
treatEvent(event)

This function is called when events are sent to the Listeners, and Listeners only. Is it passed a reference to the event that just happened. Implement that method to catch events with custom types (like for instance tlp.GraphEvent or tlp.PropertyEvent)

Parameters:event (tlp.Event or types deriving from it) – The event that was sent.
treatEvents(events)

This function is called when events are sent to Observers, and Observers only.

It is passed a list of all the events that happened since the last call. If events were on hold, this vector can be pretty large, and if events were not on hold it is likely it only contains a single element. It is important to note that custom events can not be catched with that method. Only instances of base tlp.Event type are stored in the list. Moreover when unholding events through a call to tlp.Observable.unholdObservers(), if several events were sent from the same object, only one instance of tlp.Event will be stored in the list for that sender.

Parameters:events (list of tlp.Event) – The events that happened since the last tlp.Observable.unholdObservers() call.
unholdObservers()

Static method to send all held events to the Observers.

Listeners are not affected by this function.

tlp.TulipFontAwesome

class tlp.TulipFontAwesome

Helper class for the configuration of a Font Awesome glyph.

Font Awesome is a free iconic font by Dave Gandy offering more than 500 customizable scalable vector icons.

A glyph has been added to Tulip enabling to use these great icons as nodes and edges extremities shapes.

That class offers utility functions and supported icons names constants.

To set a node glyph as a Font Awesome icon, the Font Awesome glyph must be associated to the node through the modification of the “viewShape” integer property attached to the graph. The name of the icon to use must then be set in the “viewFontAwesomeIcon” string property. As an example, the following code snippet activates the Font Awesome glyph for all nodes and sets the “user” icon ():

# graph is a pointer to a tlp.Graph object
viewShape = graph.getIntegerProperty("viewShape")
viewFontAwesomeIcon = graph.getStringProperty("viewFontAwesomeIcon")

# sets the Font Awesome glyph on all nodes
viewShape.setAllNodeValue(tlp.NodeShape.FontAwesomeIcon)
# sets the "user" glyph for all nodes
viewFontAwesomeIcon.setAllNodeValue(tlp.TulipFontAwesome.User)

The following string constants representing the supported icons are available :
