initNodeAccessors

protected void initNodeAccessors(AccessorMap nodeAccessors)

Description copied from class: AttributeOverwritingFilter

Additional (possibly overwritten) attributes for nodes have to be declared in subclasses by overriding this method. For each overwritten attribute, a suitable accessor has to be added to accessors. Instances of GraphFilter.AccessorBridge may be used for this purpose.

Overrides:

initNodeAccessors in class AttributeOverwritingFilter

Parameters:

nodeAccessors - set of node accessors

initEdgeAccessors

protected void initEdgeAccessors(AccessorMap edgeAccessors)

Description copied from class: AttributeOverwritingFilter

Additional (possibly overwritten) attributes for edges have to be declared in subclasses by overriding this method. For each overwritten attribute, a suitable accessor has to be added to accessors. Instances of GraphFilter.AccessorBridge may be used for this purpose.

Overrides:

initEdgeAccessors in class AttributeOverwritingFilter

Parameters:

edgeAccessors - set of node accessors

getDependent

public Attribute[] getDependent(Object object,
 boolean asNode,
 Attribute a)

Description copied from interface: Graph

Returns the set of attributes whose values depend on the given attribute a for the given object.

Specified by:

getDependent in interface Graph

Overrides:

getDependent in class GraphFilter

Parameters:

a - the attribute

Returns:

the set of dependent attributes

getDependentOfSource

protected Attribute[] getDependentOfSource(Object object,
 boolean asNode,
 Attribute a)

Overrides:

getDependentOfSource in class GraphFilter

isWritable

protected boolean isWritable(Object object,
 GraphFilter.AccessorBridge accessor,
 GraphState gs)

Description copied from class: GraphFilter

GraphFilter.AccessorBridge forwards the invocation of AttributeAccessor.isWritable(Object, GraphState) to this method. This method has to be overridden by subclasses which declare a writable attribute by an accessor bridge.

Overrides:

isWritable in class GraphFilter

Parameters:

accessor - an accessor bridge

gs - current graph state

Returns:

true iff accessor represents a writable attribute

 GraphFilter.AccessorBridge accessor,
 Object placeIn,
 GraphState gs)

Description copied from class: AttributeOverwritingFilter

This method has to be implemented by subclasses in order to obtain the value of an additional attribute which is defined by an GraphFilter.AccessorBridge. The default implementation returns the value of accessor's attribute in the source graph.

Overrides:

Parameters:

object - the object

accessor - the accessor bridge which invokes this method

placeIn - an instance for the result may be provided by the caller

gs - current graph state

getInt

protected int getInt(Object object,
 GraphFilter.AccessorBridge accessor,
 GraphState gs)

Description copied from class: AttributeOverwritingFilter

This method has to be implemented by subclasses in order to obtain the value of an additional attribute which is defined by an GraphFilter.AccessorBridge. The default implementation returns the value of accessor's attribute in the source graph.

Overrides:
