Deprecated.

direct reference not recommended. As of 0.9, clients should use SpecificationBuilder to convert EMF patterns to IQuerySpecifications, or GenericPatternMatcher for other purposes. Note that the class GenericPatternMatch has also been moved.

@Deprecated
public class GenericPatternMatcher
extends GenericPatternMatcher

This is a generic pattern matcher for any EMF-IncQuery pattern, with "interpretative" query execution. Use the pattern matcher on a given model via on(IncQueryEngine, Pattern), e.g. in conjunction with IncQueryEngine.on(Notifier).

Whenever available, consider using the pattern-specific generated matcher API instead.

Matches of the pattern will be represented as GenericPatternMatch.

Method Detail

on

public static GenericPatternMatcher on(IncQueryEngine engine,
                                       Pattern pattern)
                                throws IncQueryException

Deprecated.

Initializes the pattern matcher within an existing EMF-IncQuery engine. If the pattern matcher is already constructed in the engine, only a light-weight reference is returned. The match set will be incrementally refreshed upon updates.

Parameters:

engine - the existing EMF-IncQuery engine in which this matcher will be created.

pattern - the EMF-IncQuery pattern for which the matcher is to be constructed.

Throws:

IncQueryException - if an error occurs during pattern matcher creation

on

public static GenericPatternMatcher on(IncQueryEngine engine,
                                       GenericQuerySpecification querySpecification)
                                throws IncQueryException

Deprecated.

Initializes the pattern matcher within an existing EMF-IncQuery engine. If the pattern matcher is already constructed in the engine, only a light-weight reference is returned. The match set will be incrementally refreshed upon updates.

Parameters:

engine - the existing EMF-IncQuery engine in which this matcher will be created.

querySpecification - the query specification for which the matcher is to be constructed.

Throws:

IncQueryException - if an error occurs during pattern matcher creation
