Description copied from interface: GraphTraverseHandler

This method is called during a traversal to check if the current node and eventually its sub-graph shall be traversed or not. If the return value is false, the traversal for the current path, will stop at the current node and the methods #nodeReached(GRAPH_TRAVERSE_TYPE, String, SNode, SRelation, SNode, long) and #nodeLeft(GRAPH_TRAVERSE_TYPE, String, SNode, SRelation, SNode, long) as well will not be invoked. Otherwise the method #nodeReached(GRAPH_TRAVERSE_TYPE, String, SNode, SRelation, SNode, long) will be invoked, when a new node is reached and #nodeLeft(GRAPH_TRAVERSE_TYPE, String, SNode, SRelation, SNode, long) will be invoked, when this node is left.

Specified by:

checkConstraint in interface GraphTraverseHandler

Parameters:

traversalType - the type of current traversal

traversalId - the id of current traversal, given by the invoking object

edge - the relation via which the current node was reached

currNode - the current node

order - the number of the relation in the parent node

nodeLeft

public void nodeLeft(SGraph.GRAPH_TRAVERSE_TYPE traversalType,
            String traversalId,
            SNode currNode,
            SRelation edge,
            SNode fromNode,
            long order)

Description copied from interface: GraphTraverseHandler

This method will be invoked, when a node is left, after the method #checkConstraint(GRAPH_TRAVERSE_TYPE, String, SRelation, SNode, long) has returned true and the method #nodeReached(GRAPH_TRAVERSE_TYPE, String, SNode, SRelation, SNode, long) has been invoked.

Specified by:

nodeLeft in interface GraphTraverseHandler

Parameters:

traversalType - the type of current traversal

traversalId - the id of current traversal, given by the invoking object

currNode - the current node

edge - the relation via which the current node was reached

fromNode - the parent node

order - the number of the relation in the parent node

nodeReached

public void nodeReached(SGraph.GRAPH_TRAVERSE_TYPE traversalType,
               String traversalId,
               SNode currSNode,
               SRelation relation,
               SNode fromSNode,
               long order)

Description copied from interface: GraphTraverseHandler

This method will be invoked, when a node is reached, after the method #checkConstraint(GRAPH_TRAVERSE_TYPE, String, SRelation, SNode, long) has returned true and before the method #nodeLeft(GRAPH_TRAVERSE_TYPE, String, SNode, SRelation, SNode, long) is invoked.

Specified by:

nodeReached in interface GraphTraverseHandler

Parameters:

traversalType - the type of current traversal

traversalId - the id of current traversal, given by the invoking object

currSNode - the current node

relation - the relation via which the current node was reached

fromSNode - the parent node

order - the number of the relation in the parent node
