Class DefaultNameStep

java.lang.Object
  org.jaxen.expr.DefaultStep
      org.jaxen.expr.DefaultNameStep

All Implemented Interfaces:

java.io.Serializable, NameStep, Predicated, Step, Visitable

public class DefaultNameStep
extends DefaultStep
implements NameStep

Expression object that represents any flavor of name-test steps within an XPath.

This includes simple steps, such as "foo", non-default-axis steps, such as "following-sibling::foo" or "@foo", and namespace-aware steps, such as "foo:bar".
