Class GraphFilter

java.lang.Object

de.grogra.graph.GraphBase

de.grogra.graph.GraphFilter

All Implemented Interfaces:

AttributeChangeListener, ChangeBoundaryListener, EdgeChangeListener, Graph, Lockable

Direct Known Subclasses:

AttributeOverwritingFilter

public abstract class GraphFilter
extends GraphBase
implements ChangeBoundaryListener, AttributeChangeListener, EdgeChangeListener

A GraphFilter is a Graph which has another graph as source and filters the data of the source graph. Filtering may include modification of structure and attributes. The implementations of Graph methods in this class just forward their invocation to the corresponding methods of the source graph.

NoSuchKeyException - if the attribute is not defined for the object

setInt

protected int setInt(java.lang.Object object,
         GraphFilter.AccessorBridge accessor,
         int value,
         GraphState gs)

GraphFilter.AccessorBridge forwards the invocation of IntAttributeAccessor.setInt(Object, int, GraphState) to this method. This method has to be overridden by subclasses which use accessor bridges to represent writable attributes.

Parameters:

object - the object

accessor - the accessor bridge which invokes this method

value - the new value for the attribute

gs - current graph state

Returns:

actual new value of the attribute

Throws:

NoSuchKeyException - if the attribute is not defined for the object

protected long setLong(java.lang.Object object,
           GraphFilter.AccessorBridge accessor,
           long value,
           GraphState gs)

GraphFilter.AccessorBridge forwards the invocation of LongAttributeAccessor.setLong(Object, long, GraphState) to this method. This method has to be overridden by subclasses which use accessor bridges to represent writable attributes.

Parameters:

object - the object

accessor - the accessor bridge which invokes this method

value - the new value for the attribute

gs - current graph state

Returns:

actual new value of the attribute

Throws:

NoSuchKeyException - if the attribute is not defined for the object

protected java.lang.Object setObject(java.lang.Object object,
                         GraphFilter.AccessorBridge accessor,
                         java.lang.Object value,
                         GraphState gs)

GraphFilter.AccessorBridge forwards the invocation of ObjectAttributeAccessor.setObject(Object, Object, GraphState) to this method. This method has to be overridden by subclasses which use accessor bridges to represent writable attributes.

Parameters:

object - the object

accessor - the accessor bridge which invokes this method

value - the new value for the attribute

gs - current graph state

Returns:

actual new value of the attribute

Throws:

NoSuchKeyException - if the attribute is not defined for the object

             GraphState gs)

GraphFilter.AccessorBridge forwards the invocation of ShortAttributeAccessor.setShort(Object, short, GraphState) to this method. This method has to be overridden by subclasses which use accessor bridges to represent writable attributes.

Parameters:

object - the object

accessor - the accessor bridge which invokes this method

value - the new value for the attribute

gs - current graph state

Returns:

actual new value of the attribute

Throws:

NoSuchKeyException - if the attribute is not defined for the object
