Constructor Detail

GraphContextImpl

public GraphContextImpl(GraphTransformer objGraph)

Constructor.

Parameters:

objGraph - GraphTransformer

Method Detail

getConfiguration

public GraphConfiguration getConfiguration()

Description copied from interface: GraphContext

Returns configuration options for this graph. Configuration settings are only valid for one transformation which this context is bound too.

Specified by:

getConfiguration in interface GraphContext

Returns:

GraphConfiguration

getNodeFilterList

public java.util.List<PropertyFilter> getNodeFilterList()

Description copied from interface: GraphContext

Returns a modifiable List of PropertyFilter instances. This chain of filters is applied to every processed property which is treated as GraphNode.

Specified by:

getNodeFilterList in interface GraphContext

Returns:

list of PropertyFilter which are getting applied to node-properties only

getPropertyFilterList

public java.util.List<PropertyFilter> getPropertyFilterList()

Description copied from interface: GraphContext

Returns a modifiable List of PropertyFilter instances. This chain of filters is applied to every processed property (including these ones which are treated as node).

Specified by:

getPropertyFilterList in interface GraphContext

Returns:

List of PropertyFilter which are getting applied to every property

isReleased

public boolean isReleased()

Description copied from interface: GraphContext

Returns true when graph transformation process which used that context instance is finished. After a context is released it can not be used a second time for another transformation. However, it can still be used to gather some statistical data about the transformation.

Specified by:

isReleased in interface GraphContext

Returns:

true when context is released

setReleased

protected void setReleased(boolean isReleased)

getAttributes

public java.util.Map getAttributes()

Description copied from interface: GraphContext

A map of attributes which is free to use.

Specified by:

getAttributes in interface GraphContext

Returns:

Map

getMaxDistance

public int getMaxDistance()

Returns the most far away distance which was detected from start node. If graph processing is finished, it is the highest distance for that graph at all.

Specified by:

getMaxDistance in interface GraphContext

Returns:

highest distance (snapshot)

setMaxDistance

public void setMaxDistance(int distance)

getGraphTransformer

public AbstractGraphTransformer getGraphTransformer()

Returns the GraphTransformer which this context belongs to.

Specified by:

getGraphTransformer in interface GraphContext

Returns:

GraphTransformer

getProcessedNodes

public java.util.Map<java.lang.Object,java.lang.Object> getProcessedNodes()

Returns a Map of already processed nodes.

Returns:

getProcessedNodesId

public java.util.Map<java.lang.Object,java.lang.Object> getProcessedNodesId()

createRootNodeContext

protected NodeContext createRootNodeContext(CachedClassLookupMap<NodeMapping> rootNodeLookup,
                                            AbstractNodeMapping nodeMapping,
                                            java.lang.Object source)

Creates an initial NodeContext (root node context)

Parameters:

rootNodeLookup -

nodeMapping -

source -

Returns:

getRuntimeNodeMappings

protected CachedClassLookupMap<NodeMapping> getRuntimeNodeMappings(int distance)

Returns an already calculated CachedClassLookupMap.

Parameters:

distance -

Returns:

setRuntimeNodeMappings

protected void setRuntimeNodeMappings(int distance,
                                      CachedClassLookupMap<NodeMapping> nodeLookup)

buildChildNodeLookup

protected CachedClassLookupMap<NodeMapping> buildChildNodeLookup(CachedClassLookupMap<NodeMapping> base,
                                                                 CachedClassLookupMap<NodeMapping> add)

buildChildNodeLookup

protected CachedClassLookupMap<NodeMapping> buildChildNodeLookup(CachedClassLookupMap<NodeMapping> base,
                                                                 java.util.Collection<NodeMapping> add)
