Detailed Description

This is the main graph implementation, that uses a cache policy anda graph loader to get all elements inside a data source.

All methods to access a graph element (vertex or edge) will use the GraphData instance, if not found the element, the class GraphCache will be consulted.

Member Function Documentation

void te::graph::Graph::add ( Vertex * v )

virtual

Add a new vertex element to a graph.

Parameters

v	Vertex element

Note: This function turns the dirty flag of current GraphData to true, the new flag of the vertex turns to true.

Implements te::graph::AbstractGraph.

void te::graph::Graph::add ( Edge * e )

virtual

Add a new edge element to a graph.

Parameters

e	Edge element

Note: This function turns the dirty flag of current GraphData to true, the new flag of the edge turns to true.

Implements te::graph::AbstractGraph.

Reimplemented in te::graph::BidirectionalGraph, te::graph::UndirectedGraph, and te::graph::DirectedGraph.

void te::graph::Graph::addEdgeProperty ( te::dt::Property * p )

virtual

Add a new property associated to the edge element.

param p New property to be associated with edge elements.

Note: It's important before using this function call the flush() function, its necessary to force the memory clear and the elements will be loaded with the right size of properties.

Implements te::graph::AbstractGraph.

References te::graph::GraphMetadata::addEdgeProperty(), and m_metadata.

void te::graph::Graph::addVertexProperty ( te::dt::Property * p )

virtual

Add a new property associated to the vertex element.

param p New property to be associated with vertex elements.

Note: It's important before using this function call the flush() function, its necessary to force the memory clear and the elements will be loaded with the right size of properties.

void te::graph::Graph::flush ( )

virtual

Function used to clear the memory cache, all elements was released from memory, if any element was changes it will be saved.
