Constructor Detail
XPathType
- public XPathType(java.lang.String expression,
- XPathType.Filter filter)
Parameters:
expression
- the XPath expression to be evaluated filter
- the filter operation ( XPathType.Filter.INTERSECT
,
XPathType.Filter.SUBTRACT
, or XPathType.Filter.UNION
) Throws:
java.lang.NullPointerException
- if expression
or
filter
is null
XPathType
- public XPathType(java.lang.String expression,
- XPathType.Filter filter,
- java.util.Map namespaceMap)
Creates an
XPathType
instance with the specified XPath
expression, filter, and namespace map. The map is copied to protect
against subsequent modification.
Parameters:
expression
- the XPath expression to be evaluated filter
- the filter operation ( XPathType.Filter.INTERSECT
,

, or XPathType.Filter.UNION
) 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 expression

filter
or namespaceMap
are
null
java.lang.ClassCastException
- if any of the map's keys or entries are
not of type String
