Constructor Details

XPathType

public XPathType(String expression, XPathType.Filter filter)

Creates an XPathType instance with the specified XPath expression and filter.

Parameters:: expression - the XPath expression to be evaluated; filter - the filter operation (XPathType.Filter.INTERSECT, XPathType.Filter.SUBTRACT, or XPathType.Filter.UNION)
Throws:: NullPointerException - if expression or filter is null

XPathType

public XPathType(String expression, XPathType.Filter filter, Map<String,String> 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, XPathType.Filter.SUBTRACT, 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:: NullPointerException - if expression, filter or namespaceMap are null; ClassCastException - if any of the map's keys or entries are not of type String

Method Details

getExpression

public String getExpression()

Returns the XPath expression to be evaluated.

Returns:: the XPath expression to be evaluated

getFilter

public XPathType.Filter getFilter()

Returns the filter operation.

Returns:: the filter operation

getNamespaceMap

public Map<String,String> 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)
