Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

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)
