Member Function Documentation

bool Showcase::PropertyGenerator::init ( const GraphNode &  n )

virtual

This will initialize the generator.

No time consuming tasks should be done in init. The default implementation checks that the protocol-part in node id matches to the protocol of this generater.

Returns

Can this generator generate any events for the given node

bool Showcase::PropertyGenerator::init ( const GraphEdge &  e )

virtual

This will initialize the generator.

No time consuming tasks should be done in init. The default implementation checks that the protocol-part of the node id of the node that is the origin of the edge matches to the protocol of this generator.

Returns

Can this generator generate any events for the given edge

virtual bool Showcase::PropertyGenerator::init ( const PropertyEvent &  )

inlinevirtual

This will initialize the generator.

No time consuming tasks should be done in init. The default implementation returns false. For example property 'imdb-id = 1234', could launch generator that fetches data from imdb.

Returns

Can this generator generate any events based on the given property
