public DirectlyFollowsModelImplQuadratic()

Method Detail

getNodeOfIndex

public java.lang.String getNodeOfIndex(int value)

Specified by:

getNodeOfIndex in interface DirectlyFollowsModel

Returns:

The activity, or null if it does not exist.

getNumberOfNodes

public int getNumberOfNodes()

Specified by:

getNumberOfNodes in interface DirectlyFollowsModel

Returns:

The number of nodes in the model.

getAllNodeNames

public java.lang.String[] getAllNodeNames()

Specified by:

getAllNodeNames in interface DirectlyFollowsModel

Returns:

The added node names, in the order they were added.

getNodeIndices

public java.lang.Iterable<java.lang.Integer> getNodeIndices()

Specified by:

getNodeIndices in interface DirectlyFollowsModel

getIndicesOfNodeName

public gnu.trove.set.TIntSet getIndicesOfNodeName(java.lang.String activity)

Specified by:

getIndicesOfNodeName in interface DirectlyFollowsModel

Returns:

The indices of the nodeName.

addNode

public int addNode(java.lang.String activity)

Description copied from interface: DirectlyFollowsModel

Inserts an activity.

Specified by:

addNode in interface DirectlyFollowsModel

Returns:

the index of the newly added node.

addNodes

public void addNodes(java.lang.String[] activities)

Description copied from interface: DirectlyFollowsModel

Adds an array of nodes with the provided names. Typically more efficient than adding the nodes one-by-one.

Specified by:

addNodes in interface DirectlyFollowsModel

isEmptyTraces

public boolean isEmptyTraces()

Specified by:

isEmptyTraces in interface DirectlyFollowsModel

Returns:

Whether the model supports empty (epsilon) traces.

setEmptyTraces

public void setEmptyTraces(boolean emptyTraces)

Description copied from interface: DirectlyFollowsModel

Set whether the model supports empty (epsilon) traces.

Specified by:

setEmptyTraces in interface DirectlyFollowsModel

addEdge

public void addEdge(int sourceIndex,
                    int targetIndex)

Description copied from interface: DirectlyFollowsModel

Adds an edge. Has no effect if the edge was already present.

Specified by:

addEdge in interface DirectlyFollowsModel

removeEdge

public void removeEdge(int sourceIndex,
                       int targetIndex)

Description copied from interface: DirectlyFollowsModel

Removes an edge. Has no effect if the edge was not present.

Specified by:

removeEdge in interface DirectlyFollowsModel

getEdges

public java.lang.Iterable<java.lang.Long> getEdges()

Description copied from interface: DirectlyFollowsModel

Gives an iterable that iterates over all edges; The edges that are returned are indices. The iterable supports remove() calls, however calls to this method might invalidate other iterables.

Specified by:

getEdges in interface DirectlyFollowsModel

Returns:

containsEdge

public boolean containsEdge(int sourceIndex,
                            int targetIndex)

Description copied from interface: DirectlyFollowsModel

Returns whether the graph contains an edge between source and target.

Specified by:

containsEdge in interface DirectlyFollowsModel

Returns:

getEdgeSource

public int getEdgeSource(long edgeIndex)

Description copied from interface: DirectlyFollowsModel

Returns the node the edgeIndex comes from.

Specified by:

getEdgeSource in interface DirectlyFollowsModel

Returns:

getEdgeTarget

public int getEdgeTarget(long edgeIndex)

Description copied from interface: DirectlyFollowsModel

Returns the node the edgeIndex points to.

Specified by:

getEdgeTarget in interface DirectlyFollowsModel

Returns:

hasStartNodes

public boolean hasStartNodes()

Specified by:

hasStartNodes in interface DirectlyFollowsModel

getStartNodes

public gnu.trove.set.TIntSet getStartNodes()

Specified by:
