public NodeTestPatternADJ(Pattern p)

Method Detail

optimizeForName

public Pattern optimizeForName(int i)

Description copied from class: PatternADJ

Optimize a pattern with respect to a named node (element or attribute). This is usually carried out on the base pattern, to determine if it will match the named node to be matched.

Overrides:

optimizeForName in class PatternADJ

Parameters:

i - the fingerprint of the name of the node to be matched.

Returns:

null if it isn't for this named node, otherwise the pattern itself.

optimizeForType

public Pattern optimizeForType(int i)

Description copied from class: PatternADJ

Optimize a pattern with respect to a typed node. This is usually carried out on the base pattern, to determine if it will match the typed node to be matched.

Overrides:

optimizeForType in class PatternADJ

Parameters:

i - the type of the node to be matched.

Returns:

null if it isn't for this type of node, otherwise the pattern itself.

optimizePattern

public Pattern optimizePattern()

Description copied from class: PatternADJ

Generic optimization of a pattern

Overrides:

optimizePattern in class PatternADJ

Returns:

the optimization of the pattern

unify

public Pattern unify(PatternADJ source,
            RewriteContext rc)

Overrides:

unify in class PatternADJ

unifyingBindings

public Set<RewriteContext> unifyingBindings(PatternADJ source,
                                   RewriteContext rc)

Description copied from class: PatternADJ

Unify this expression against another expression

Overrides:

unifyingBindings in class PatternADJ

Parameters:

source - the expression to be unified against

rc - the evaluation context to use (which may be side-effected)

Returns:

a set of rewrite context bindings if it can unify, otherwise null

equals

public boolean equals(Object o)

Overrides:

equals in class Object
