XPathFilterParameterSpec

• java.lang.Object

<element name="XPath" type="string"/>

Fields Summary
private String	xPath
private Map	nsMap

Constructors Summary
public XPathFilterParameterSpec(String xPath) Creates an XPathFilterParameterSpec with the specified XPath expression. param xPath the XPath expression to be evaluated throws NullPointerException if xPath is null if (xPath == null) { throw new NullPointerException(); } this.xPath = xPath; this.nsMap = Collections.EMPTY_MAP;
public XPathFilterParameterSpec(String xPath, Map namespaceMap) Creates an XPathFilterParameterSpec with the specified XPath expression and namespace map. The map is copied to protect against subsequent modification. param xPath the XPath expression to be evaluated param namespaceMap the map of namespace prefixes. Each key is a namespace prefix String that maps to a corresponding namespace URI String. throws NullPointerException if xPath or namespaceMap are null throws ClassCastException if any of the map's keys or entries are not of type String if (xPath == null || namespaceMap == null) { throw new NullPointerException(); } this.xPath = xPath; nsMap = new HashMap(namespaceMap); Iterator entries = nsMap.entrySet().iterator(); while (entries.hasNext()) { Map.Entry me = (Map.Entry) entries.next(); if (!(me.getKey() instanceof String) || !(me.getValue() instanceof String)) { throw new ClassCastException("not a String"); } } nsMap = Collections.unmodifiableMap(nsMap);

Methods Summary
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 {@link Collections#unmodifiableMap unmodifiable map}. return a Map of namespace prefixes to namespace URIs (may be empty, but never null) return nsMap;
public java.lang.String	getXPath() Returns the XPath expression to be evaluated. return the XPath expression to be evaluated return xPath;
