addEdgeBits

public void addEdgeBits(java.lang.Object source,
               java.lang.Object target,
               int bits)

Description copied from class: RuntimeModel

Adds a set of edge bits from a source node to a target node.

Specified by:

addEdgeBits in class RuntimeModel

Parameters:

source - the source node of the edge

target - the target node of the edge

bits - the edge bits that are to be added

createEdgeIterator

public EdgeIterator createEdgeIterator(java.lang.Object node,
                              EdgeDirection dir)

Description copied from class: RuntimeModel

Creates an iterator over the edges of node. The iterator is set to the first edge of the node, if any. The direction dir has to be respected by the iterator.

Specified by:

createEdgeIterator in class RuntimeModel

Parameters:

node - the node whose edges are to be iterated

dir - direction in which edges are traversed (seen from node)

Returns:

an edge iterator

currentGraph

public RGGGraph currentGraph()

Description copied from interface: RuntimeModel

Returns the graph that shall be used in the context of the current thread. This is needed by graph-related XL statements which do not explicitly specify the graph to use.

Specified by:

currentGraph in interface RuntimeModel

Overrides:

currentGraph in class RuntimeModel

Returns:

the current graph for this model

getEdgeBits

public int getEdgeBits(java.lang.Object source,
              java.lang.Object target)

Description copied from class: RuntimeModel

Return the edge bits between a source node and a target node. If there is no edge at all, 0 is returned.

Specified by:

getEdgeBits in class RuntimeModel

Parameters:

source - the source node of the edge

target - the target node of the edge

Returns:

the edge bits

getNodeType

public java.lang.Class getNodeType()

Description copied from class: RuntimeModel

Specifies the base type of nodes of this runtime model. This should return the same type as CompiletimeModel.getNodeType() for the corresponding CompiletimeModel implementation.

Specified by:

getNodeType in class RuntimeModel

Returns:

base type of nodes

isNode

public boolean isNode(java.lang.Object value)

Description copied from interface: RuntimeModel

Determines if value represents a valid node for this run-time model.

Specified by:

isNode in interface RuntimeModel

Overrides:

isNode in class RuntimeModel

Parameters:

value - the value to be tested

Returns:

true iff the value represents a node

isWrapperFor

public boolean isWrapperFor(java.lang.Object wrapper,
                   Type type)

Description copied from interface: RuntimeModel

Tests if the object is a wrapper for values of the given type.

Specified by:

isWrapperFor in interface RuntimeModel

Overrides:

isWrapperFor in class RuntimeModel

Parameters:

wrapper - the potential wrapper to be tested

type - the value type

Returns:

true iff object is a wrapper for values of type type

setCurrentGraph

public void setCurrentGraph(Graph extent)

Overrides:

setCurrentGraph in class RuntimeModel

setCurrentGraph

public void setCurrentGraph(GraphManager graph)

unwrapBoolean
