Method Detail

getGraphIds

public GradoopIdSet getGraphIds()

Description copied from interface: GraphElement

Returns all graphs that element belongs to.

Specified by:

getGraphIds in interface GraphElement

Returns:

all graphs of that element

Adds the given graph set to the element.

Specified by:

setGraphIds in interface GraphElement

Parameters:

graphIds - the graphIds to be added

resetGraphIds

public void resetGraphIds()

Description copied from interface: GraphElement

Resets all graph elements.

Specified by:

resetGraphIds in interface GraphElement

getGraphCount

public int getGraphCount()

Description copied from interface: GraphElement
