Constructor Detail

AbsolutePathPattern

public AbsolutePathPattern()

Construct an AbsolutePathPattern that corresponds to the following: LocationPathPattern ::= '/'

AbsolutePathPattern

public AbsolutePathPattern(RelativePathPattern pattern)

Construct an AbsolutePathPattern that corresponds to: LocationPathPattern ::= '/' RelativeLocationPath

Parameters:

pattern - The RelativeLocationPath after the '/'

Method Detail

toString

public String toString()

Provide a readable description for debugging.

Overrides:

toString in class RelativePathPattern

Returns:

String representation

performMatch

protected Node performMatch(Node node,
                            ExpressionContext context)
                     throws XPathEvaluationException

Perform the match semantics on the passed node. Return the left-most-matching node. This member overrides RelativePathPattern.performMatch()

Overrides:

performMatch in class RelativePathPattern

Parameters:

node - The node to match.

context - The expression context for matching. must be a child of the root

Returns:

Node that matches left-most step in path pattern

Throws:

XPathEvaluationException

getDefaultPriority

public double getDefaultPriority()

Return the default priority for this pattern. See XSLT spec for information on default priority calculation.

Specified by:

getDefaultPriority in interface Pattern

Overrides:

getDefaultPriority in class RelativePathPattern

Returns:

-0.5, 0.0, or 0.5

getTarget

public int getTarget()

Return the target type of this Pattern. This is one of the values defined in the Pattern interface (ELEMENT_NAMED_TARGET, ELEMENT_WILDCARD_TARGET, etc.)

Specified by:

getTarget in interface Pattern

Overrides:

getTarget in class RelativePathPattern

Returns:

The target type value for this Pattern.

getTargetName

public ExpandedQName getTargetName()

Return the name of the patterns target, if there is a target name. This may return null if there is no target name for this pattern (text(), node(), etc.). However, if getTarget() returns ELEMENT_NAMED_TARGET or ATTRIBUTE_NAMED_TARGET this will never return null.

Specified by:

getTargetName in interface Pattern

Overrides:

getTargetName in class RelativePathPattern

Returns:

The target name or null.
