Detailed Description

A container that can store data from any type.

The DataSet aggregate data of various types into a single structure and map each value to a key (std::string) describing its name. DataSet is mainly used in plugins. When creating a plugin, one can add input parameters (using tlp::WithParameter methods) and retrieve them from the dataSet member variable once they have been set by the user.

bool tlp::DataSet::empty ( ) const

Indicates whether the set is empty of not.

bool tlp::DataSet::exist ( const std::string & str ) const

Parameters

str	the name of the member to look for

Returns: true if str exists into the DataSet.

template<typename T >

bool tlp::DataSet::get	(	const std::string &	key,
		T &	value
	)		const

Returns the stored value associated with the given key. The stored value is a copy of the original value that was set. If there is no value associated with the given key, the input value is left untouched.

Parameters

key	The key with which the data we want to retrieve is associated.
value	A variable wich will be overwritten with the value to retrieve.

Returns: bool Whether there is a value associated with given key or not.

Definition at line 22 of file DataSet.cxx.

Here is the caller graph for this function:

template<typename T >

bool tlp::DataSet::getAndFree	(	const std::string &	key,
		T &	value
	)

Returns the stored value, and deletes the stored copy. If no value is found, nothing is deleted.

Parameters

key	The key with which the data we want to retrieve is associated.
value	A variable wich will be overwritten with the value to retrieve.

Returns: bool Whether there is a value associated with given key or not.

Definition at line 36 of file DataSet.cxx.

DataType* tlp::DataSet::getData ( const std::string & str ) const

Parameters

str	The name of the element to retrieve

Returns: A untyped value for a given element name. NULL if the element does not exist

tlp::Iterator< std::pair<std::string, DataType*> >* tlp::DataSet::getValues ( ) const

Returns: An iterator over stored values as a std::pair name => untyped value

DataSet& tlp::DataSet::operator= ( const DataSet & set )

Performs a deep copy of a DataSet into another.

static bool tlp::DataSet::read	(	std::istream &	is,
		DataSet &	ds
	)

static

Reads a stream and stores its contents into a DataSet.

bool tlp::DataSet::readData	(	std::istream &	is,
		const std::string &	prop,
		const std::string &	outputTypeName
	)

Read a value and stores it into the specified type.

template<typename T >

static void tlp::DataSet::registerDataTypeSerializer ( const DataTypeSerializer & serializer )

inlinestatic

Registers a serializer for a known type.

Serializers are used to write/read from std::ostream objects when saving DataSet instances.

Definition at line 229 of file DataSet.h.

void tlp::DataSet::remove ( const std::string & str )

Removes an element from the DataSet.

Parameters

str	the name of the element to remove

template<typename T >

void tlp::DataSet::set	(	const std::string &	key,
		const T &	value
	)

Stores a copy of the given param, associated with the key. The value must have a well-formed copy constructor.

Parameters

key	The key which can be used to retrieve the data.
value	The data to store.

Returns: void

Here is the call graph for this function:

Here is the caller graph for this function:

void tlp::DataSet::setData	(	const std::string &	str,
		const DataType *	value
	)

Set from an untyped value.

Here is the caller graph for this function:

unsigned int tlp::DataSet::size ( ) const

Returns the number of registered values.

std::string tlp::DataSet::toString ( ) const

Returns: A std::string representation of a DataSet

static DataTypeSerializer* tlp::DataSet::typenameToSerializer ( const std::string & name )

static

Returns: the data type serializer associated to the given typename. NULL if no serializer is found

static void tlp::DataSet::write	(	std::ostream &	os,
		const DataSet &	ds
	)

static

Serializes a DataSet into a stream.

void tlp::DataSet::writeData	(	std::ostream &	os,
		const std::string &	prop,
		const DataType *	dt
	)		const

write an embedded value
