Constructor Detail

GraphElement

protected GraphElement()

Default constructor.

GraphElement

protected GraphElement(GradoopId id,
                       String label,
                       Properties properties,
                       GradoopIdSet graphIds)

Creates an EPGM graph element using the given arguments.

Parameters:

id - element id

label - element label

properties - element properties

graphIds - graphIds that element is contained in

Method Detail

getGraphIds

public GradoopIdSet getGraphIds()

Returns all graphs that element belongs to.

Specified by:

getGraphIds in interface EPGMGraphElement

Returns:

all graphs of that element

addGraphId

public void addGraphId(GradoopId graphId)

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

Specified by:

addGraphId in interface EPGMGraphElement

Parameters:

graphId - the graphId to be added to

setGraphIds

public void setGraphIds(GradoopIdSet graphIds)

Adds the given graph set to the element.

Specified by:

setGraphIds in interface EPGMGraphElement

Parameters:

graphIds - the graphIds to be added

resetGraphIds

public void resetGraphIds()

Resets all graph elements.

Specified by:

resetGraphIds in interface EPGMGraphElement

getGraphCount

public int getGraphCount()

Returns the number of graphs this element belongs to.

Specified by:

getGraphCount in interface EPGMGraphElement

Returns:

number of graphs containing that element

toString

public String toString()

Overrides:

toString in class Element
