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

index

public Set<IndexDefn.Indexation> index(List<IndexDefn> idfl)

Description copied from class: Adjunct

find any indexable terms for the attached pattern or expression

Overrides:

Parameters:

idfl - definitions of indexation directives

Returns:
