Constructor Detail
XPathFilterParameterSpec
public XPathFilterParameterSpec(String xPath)
Creates anXPathFilterParameterSpecwith the specified XPath expression.- Parameters:
-
xPath- the XPath expression to be evaluated - Throws:
-
NullPointerException- ifxPathisnull
XPathFilterParameterSpec
public XPathFilterParameterSpec(String xPath, Map namespaceMap)
Creates anXPathFilterParameterSpecwith the specified XPath expression and namespace map. The map is copied to protect against subsequent modification.- Parameters:

-
NullPointerException- ifxPathornamespaceMaparenull -
ClassCastException- if any of the map's keys or entries are not of typeString
