Constructor Detail

XPathFilterParameterSpec

  1. public XPathFilterParameterSpec( java.lang.String xPath)
Creates an XPathFilterParameterSpec with the specified XPath expression.
Parameters:
xPath - the XPath expression to be evaluated
Throws:
java.lang.NullPointerException - if xPath is null

XPathFilterParameterSpec

  1. public XPathFilterParameterSpec( java.lang.String xPath,
  2. java.util.Map namespaceMap)
Creates an XPathFilterParameterSpec with the specified XPath expression and namespace map. The map is copied to protect against subsequent modification.
Parameters:
xPath - the XPath expression to be evaluated
namespaceMap - the map of namespace prefixes. Each key is a namespace prefix String that maps to a corresponding namespace URI String.
Throws:
java.lang.NullPointerException - if xPath or namespaceMap are null
java.lang.ClassCastException - if any of the map's keys or entries are not of type String

Method Detail

getXPath

  1. public java.lang.String getXPath( )
Returns the XPath expression to be evaluated.
Returns:
the XPath expression to be evaluated

getNamespaceMap

  1. public java.util.Map getNamespaceMap( )
Returns a map of namespace prefixes. Each key is a namespace prefix String that maps to a corresponding namespace URI String.

This implementation returns an unmodifiable map.

Returns:
a Map of namespace prefixes to namespace URIs (may be empty, but never null)
