PLUGIN(CLASS_NAME)

Copy an existing Tulip interactor and sets it compatible with a given View.

This macro is used when you're making your own View and want to use an existing interactor with it. Interactors are declared to be compatible with a list of View. This macro extends the compatibility of an existing interactor by subclassing it.

Note

: This macro used the same interactor priority as the base interactor. To define your own priority, see INTERACTORPLUGINVIEWEXTENSIONWITHPRIORITY

Parameters

CLASS_NAME	The name of the interactor class to generate.
STRING_CLASS_NAME	The name of the interactor plugin to generate (see tlp::Plugin::name())
BASE_INTERACTOR_STRING_NAME	The name of the interactor to extend
VIEW_STRING_NAME	The name of the View to set the interactor compatible with
AUTHOR	see tlp::Plugin::author()
DATE	see tlp::Plugin::date()
DESCRIPTION	see tlp::Plugin::info()
VERSION	see tlp::Plugin::version()

C##Factory C##FactoryInitializer;               \
}

Register a plugin into the plugin system. This macro is mandatory in order to register a plugin into Tulip. This will generate a Factory that will handle the plugin's creation.

Parameters

C	The classname of the plugin.

Note

This macro should be called outside of the class body

// This sample shows a basic skeleton for a plugin class declaration:
class MyPlugin: public tlp::PluginBase { // tlp::PluginBase is replaced by the acutal Plugin interface (tlp::Algorithm, tlp::View, etc)
  public:
  PLUGININFORMATIONS("My plugin", "Me", "28/09/2012", "My first plugin example", "1.0", "")
  // Class declaration and extra methods
};

PLUGIN(MyPlugin) // Register MyPlugin into Tulip

Definition at line 229 of file Plugin.h.

#define PLUGININFORMATIONS	(		NAME,
			AUTHOR,
			DATE,
			INFO,
			RELEASE,
			GROUP
	)

Value:

std::string name() const { return NAME; } \
std::string author() const { return AUTHOR; }\
std::string date() const { return DATE; }  \
std::string info() const { return INFO; }  \
std::string release() const { return RELEASE; }\
std::string tulipRelease() const { return TULIP_MM_RELEASE; }\
std::string group() const { return GROUP; }

Declare meta-informations for a plugin This is an helper macro that defines every function related to a plugin meta-informations (Plugin name, author, etc). When creating a new plugin, this macro avoids having to define pure-virtual methods located into the Plugin interface and put them on the same line.

Note

PLUGINIFORMATIONS should be declared into the Plugin's class body into the public scope

Parameters

NAME	The plugin name as it will be registered into the plugins system (tlp::Plugin::name())
AUTHOR	The author of the plugin (tlp::Plugin::author())
DATE	The creation date (tlp::Plugin::date())
INFO	The plugin's description (tlp::Plugin::info())
RELEASE	The plugin's version number (tlp::Plugin::version())
GROUP	The plugin's group (tlp::Plugin::group()). If the plugin does not belong to any group, set GROUP to "".

Enumeration Type Documentation

enum tlp::ParameterDirection

The ParameterDirection enum describes how a parameter is passed to a plugin The parameter can be seen as passing parameters to a C++ functions and works as follow: .

• IN_PARAM: The parameter is passes by value
• OUT_PARAM: The parameter is a return value
• INOUT_PARAM: The parameter is passed by reference.

Definition at line 46 of file WithParameter.h.

enum tlp::ProgressState

This enum describes callback actions for the underleying system when calling tlp::PluginProgress::progress(); .

• TLP_CONTINUE: tells that the process monitored by the the progress should continue.
• TLP_CANCEL: The process should be cancelled, reverting all changes since it was started.
• TLP_STOP: The process should stop, leaving all the changes made since the beginning

See Also

tlp::PluginProgress

Enumerator:

TLP_CONTINUE	The plugin should continue its execution.
TLP_CANCEL	The plugin should cancel, reverting all performed changes since the plugin was called.
TLP_STOP	The plugin should stop, leaving the graph in its current state.

Definition at line 57 of file PluginProgress.h.

Function Documentation

std::string tlp::demangleTlpClassName

(

const char *

className

)

Demangles the name of a C++ class defined in the tlp namespace. Simply removes the 'tlp::' prefix from the class name.

Returns

string The demangled name of a Tulip C++ class.

std::string tlp::getMajor

(

const std::string &

release

)

Splits the string and returns everything befor the first dot ('.'). This is used to return major version number, as version numbers are formatted as X.Y.Z, X being the major, Y the minor, and Z the patch version.

Returns

string The part of the string before the first dot.

std::string tlp::getMinor

(

const std::string &

release

)

Splits the string and return the minor version. If the string does not contain any dot, then 0 is returned. If the string contains only one dot (X.Y), then everything after the first dot is returned (Y). If the string is a full version with two dots (X.Y.Z), everything between the first and last dots is returned (Y). If there are more than two dots, everything between the first and last dots is returned.

void tlp::initTulipLib

(

const char *

appDirPath = NULL

)

Initializes the Tulip library. Looks for the Tulip plug-ins directory, and loads the plug-ins from it. The plug-ins directory can be defined in different ways, given by order of prevalence :

1. the TLP_DIR environment variable, if it has a value
2. the appDirPath parameter, if it is not NULL
3. at that point, the Tulip paths will be retrieved from the path of the loaded Tulip shared library (you must dispose of a standard Tulip installation for that feature to work).
4. a fallback value of 'C:/Tulip/lib/' on windows, or '/usr/local/lib/' on Unix.
