public interface GraphElement
extends Element

A graph element is part of a graph. An element can be part of more than one graph. This applies to vertices and edges.

Method Detail

getGraphIds

GradoopIdSet getGraphIds()

Returns all graphs that element belongs to.

Returns:

all graphs of that element

addGraphId

void addGraphId(GradoopId graphId)

Adds that element to the given graphId. If the element is already an element of the given graphId, nothing happens.

Parameters:

graphId - the graphId to be added to

setGraphIds

void setGraphIds(GradoopIdSet graphIds)

Adds the given graph set to the element.

Parameters:

graphIds - the graphIds to be added

resetGraphIds

void resetGraphIds()

Resets all graph elements.

getGraphCount

int getGraphCount()

Returns the number of graphs this element belongs to.

Returns:

number of graphs containing that element
