Constructor Detail

NodeTraversal.AbstractNodeTypePruningCallback

public NodeTraversal.AbstractNodeTypePruningCallback(Set<Integer> nodeTypes)

Creates an abstract pruned callback.

Parameters:

nodeTypes - the nodes to include in the traversal

NodeTraversal.AbstractNodeTypePruningCallback

public NodeTraversal.AbstractNodeTypePruningCallback(Set<Integer> nodeTypes,
                                             boolean include)

Creates an abstract pruned callback.

Parameters:

nodeTypes - the nodes to include/exclude in the traversal

include - whether to include or exclude the nodes in the traversal

Method Detail

shouldTraverse

public boolean shouldTraverse(NodeTraversal nodeTraversal,
                     Node n,
                     Node parent)

Description copied from interface: NodeTraversal.Callback

Visits a node in pre order (before visiting its children) and decides whether this node's children should be traversed. If children are traversed, they will be visited by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) in postorder.

Implementations can have side effects (e.g. modifying the parse tree).

Specified by:

shouldTraverse in interface NodeTraversal.Callback

Returns:

whether the children of this node should be visited
