Interface BooleanExprVisitor

All Known Subinterfaces:

Visitor

public interface BooleanExprVisitor

Add functionality to subclasses of BooleanExpr. This is a participant in the Visitor Pattern [Gamma et al, #331]. You pass a visitor to the XPath.accept method which then passes it to all the nodes on the parse tree, each one of which calls back one of the visitor's visit methods.
