Class OrderedNodesGraph

java.lang.Object
  net.sourceforge.combean.graph.decorators.AbstractDecoratedGraph
      net.sourceforge.combean.graph.decorators.OrderedNodesGraph

All Implemented Interfaces:

Graph, GlobalNodesGraphProp, NestedGraphProp

public class OrderedNodesGraph
extends AbstractDecoratedGraph
implements GlobalNodesGraphProp

A decorator which returns a specific all nodes iterator, i.e., which enforces traversal of the nodes of the graph in a given order.

Constructor Summary

OrderedNodesGraph(GlobalNodesGraphProp g, NodeIterator itAllNodes)
Constructor

Method Summary

NodeIterator	getAllNodesIterator() Return an iterator for all nodes in the graph
int	getNumNodes() Return number of nodes in the graph.
boolean	mayNestGraphProp(Class wantedProp) All nested properties except those which refer to the global nodes and their identity (GlobalNodesGraphProp and derivatives) may be nested.

Constructor Detail

OrderedNodesGraph

public OrderedNodesGraph(GlobalNodesGraphProp g,
                         NodeIterator itAllNodes)

Constructor

Parameters:

g - the graph the nodes of which shall be traversed in a specific order

itAllNodes - the iterator (with the current implementation getAllNodesIterator() may only be invoked once on the decorated graph)

Method Detail

getNumNodes

public int getNumNodes()

Description copied from interface: GlobalNodesGraphProp

Return number of nodes in the graph.

Specified by:

getNumNodes in interface GlobalNodesGraphProp

Returns:

number of nodes

getAllNodesIterator

public NodeIterator getAllNodesIterator()

Description copied from interface: GlobalNodesGraphProp

Return an iterator for all nodes in the graph

Specified by:

getAllNodesIterator in interface GlobalNodesGraphProp

Returns:

iterator through all nodes

mayNestGraphProp

public boolean mayNestGraphProp(Class wantedProp)

All nested properties except those which refer to the global nodes and their identity (GlobalNodesGraphProp and derivatives) may be nested.

Specified by:

mayNestGraphProp in interface NestedGraphProp

Parameters:

wantedProp - the property which the user wants to use

Returns:

true if the user may access the nested graph for obtaining the wanted property
