Constructor Detail

Pattern

public Pattern()

Creates a new default pattern. This pattern has zero location paths and will match no nodes.

        throws PatternException

Method Detail

getMatchingPattern

public LocationPathPattern getMatchingPattern(XPathNode node,
                                              XPathContext context)
                                       throws XPathException

Returns the LocationPathPattern with the highest priority that matches the given XPathNode using the given XPathContext.

Parameters:

node - the node to determine a match for

context - the XPathContext

Returns:

the LocationPathPattern with the highest priority that matches the given XPathNode using the given XPathContext. Null will be returned if no matching LocationPathPattern objects are contained in this Pattern.

XPathException

matches

public boolean matches(XPathNode node,
                       XPathContext context)
                throws XPathException

Determines if the given node is matched by this Pattern with respect to the given context.

Parameters:

node - the node to determine a match for

context - the XPathContext

Returns:

true if the given node is matched by this Pattern

Throws:

XPathException - when an error occurs during evaluation

toString

public java.lang.String toString()

Returns the String representation of this Pattern. This will be an equivalent string to that which this pattern was created from, or the empty string if this pattern is the default pattern.

Overrides:

toString in class java.lang.Object

Returns:

the String representation of this Pattern.
