Method Detail

instance

public static ElementOwnerQuerySpecification instance()
                                               throws IncQueryException

Returns:

the singleton instance of the query specification

Throws:

IncQueryException - if the pattern definition could not be loaded

newEmptyMatch

public ElementOwnerMatch newEmptyMatch()

Description copied from interface: IQuerySpecification

Returns an empty, mutable Match compatible with matchers of this query. Fields of the mutable match can be filled to create a partial match, usable as matcher input. This can be used to call the matcher with a partial match even if the specific class of the matcher or the match is unknown.

Returns:

the empty match

newMatch

public ElementOwnerMatch newMatch(java.lang.Object... parameters)

Description copied from interface: IQuerySpecification

Returns a new (partial) Match object compatible with matchers of this query. This can be used e.g. to call the matcher with a partial match.

The returned match will be immutable. Use IQuerySpecification.newEmptyMatch() to obtain a mutable match object.

Parameters:

parameters - the fixed value of pattern parameters, or null if not bound.

Returns:

the (partial) match object.
