Method Summary

static EdgePredicate	create(Graph.Edge edge) Creates a new EdgePredicate which tests for Graph.Edges which look just like the specified edge.
static EdgePredicate	createEquals(Object userObject, Object firstNode, Object secondNode, int directionFlags) Creates a new EdgePredicate which tests for Graph.Edges that contain the specified user object, have the specified endpoints, and have the specified direction relative to firstNode.
static EdgePredicate	createEqualsNodes(Object firstNode, Object secondNode, int directionFlags) Creates a new EdgePredicate which tests for Graph.Edges that have the specified endpoints and direction relative to firstNode.
static EdgePredicate	createEqualsUser(Object userObject, int directionFlags) Creates a new EdgePredicate which tests for Graph.Edges that contain the specified user object and have the specified directedness.
static EdgePredicate	createPredicated(org.apache.commons.collections.Predicate userObjectPredicate, org.apache.commons.collections.Predicate firstNodePredicate, org.apache.commons.collections.Predicate secondNodePredicate, int directionFlags) Creates a new EdgePredicate which tests for Graph.Edges whose contained user object and endpoints satisfy the specified Predicates, and which have the specified direction relative to the endpoint satisyfing the firstNodePredicate.

Method Detail

create

public static final EdgePredicate create(Graph.Edge edge)

Creates a new EdgePredicate which tests for Graph.Edges which look just like the specified edge. To pass the returned Predicate, an edge must have the same endpoints, contained user object, and directedness. If the specified edge is undirected, then the endpoints may be swapped and still be valid.

createEqualsNodes

public static final EdgePredicate createEqualsNodes(Object firstNode,
                                                    Object secondNode,
                                                    int directionFlags)

Creates a new EdgePredicate which tests for Graph.Edges that have the specified endpoints and direction relative to firstNode.

createEqualsUser

public static final EdgePredicate createEqualsUser(Object userObject,
                                                   int directionFlags)

Creates a new EdgePredicate which tests for Graph.Edges that contain the specified user object and have the specified directedness.

createEquals

public static final EdgePredicate createEquals(Object userObject,
                                               Object firstNode,
                                               Object secondNode,
                                               int directionFlags)

Creates a new EdgePredicate which tests for Graph.Edges that contain the specified user object, have the specified endpoints, and have the specified direction relative to firstNode.

createPredicated

public static final EdgePredicate createPredicated(org.apache.commons.collections.Predicate userObjectPredicate,
                                                   org.apache.commons.collections.Predicate firstNodePredicate,
                                                   org.apache.commons.collections.Predicate secondNodePredicate,
                                                   int directionFlags)

Creates a new EdgePredicate which tests for Graph.Edges whose contained user object and endpoints satisfy the specified Predicates, and which have the specified direction relative to the endpoint satisyfing the firstNodePredicate.
