All Implemented Interfaces:

ViatraQueryMatcher<NegativeTransitionMatch>

public class NegativeTransitionMatcher
extends BaseMatcher<NegativeTransitionMatch>

Generated pattern matcher API of the org.eclipse.viatra.cep.core.engine.compiler.negativeTransition pattern, providing pattern-specific query methods.

Use the pattern matcher on a given model via on(ViatraQueryEngine), e.g. in conjunction with ViatraQueryEngine#on(Notifier).

Matches of the pattern will be represented as NegativeTransitionMatch.

Original source:

 pattern negativeTransition(transition : TypedTransition) {
        NegativeTransition(transition);
 }

Method Detail

on

public static NegativeTransitionMatcher on(ViatraQueryEngine engine)
                                    throws ViatraQueryException

Initializes the pattern matcher within an existing VIATRA Query 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 VIATRA Query engine in which this matcher will be created.

Throws:

ViatraQueryException - if an error occurs during pattern matcher creation

create

public static NegativeTransitionMatcher create()
                                        throws ViatraQueryException

Returns:

an initialized matcher

Throws:

ViatraQueryException - if an error occurs during pattern matcher creation

No Reference:

This method is for internal matcher initialization by the framework, do not call it manually.

getAllMatches

public java.util.Collection<NegativeTransitionMatch> getAllMatches(TypedTransition pTransition)

Returns the set of all matches of the pattern that conform to the given fixed values of some parameters.

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

Returns:

matches represented as a NegativeTransitionMatch object.

getOneArbitraryMatch

public NegativeTransitionMatch getOneArbitraryMatch(TypedTransition pTransition)

Returns an arbitrarily chosen match of the pattern that conforms to the given fixed values of some parameters. Neither determinism nor randomness of selection is guaranteed.

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

Returns:

a match represented as a NegativeTransitionMatch object, or null if no match is found.

hasMatch

public boolean hasMatch(TypedTransition pTransition)

Indicates whether the given combination of specified pattern parameters constitute a valid pattern match, under any possible substitution of the unspecified parameters (if any).

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

Returns:

true if the input is a valid (partial) match of the pattern.

countMatches

public int countMatches(TypedTransition pTransition)

Returns the number of all matches of the pattern that conform to the given fixed values of some parameters.

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

Returns:

the number of pattern matches found.

forEachMatch

public void forEachMatch(TypedTransition pTransition,
                         IMatchProcessor<? super NegativeTransitionMatch> processor)

Executes the given processor on each match of the pattern that conforms to the given fixed values of some parameters.

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

processor - the action that will process each pattern match.

forOneArbitraryMatch

public boolean forOneArbitraryMatch(TypedTransition pTransition,
                                    IMatchProcessor<? super NegativeTransitionMatch> processor)

Executes the given processor on an arbitrarily chosen match of the pattern that conforms to the given fixed values of some parameters. Neither determinism nor randomness of selection is guaranteed.

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

processor - the action that will process the selected match.

Returns:

true if the pattern has at least one match with the given parameter values, false if the processor was not invoked

newMatch

public NegativeTransitionMatch newMatch(TypedTransition pTransition)

Returns a new (partial) match. This can be used e.g. to call the matcher with a partial match.

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

Parameters:

pTransition - the fixed value of pattern parameter transition, or null if not bound.

Returns:

the (partial) match object.

rawAccumulateAllValuesOftransition

protected java.util.Set<TypedTransition> rawAccumulateAllValuesOftransition(java.lang.Object[] parameters)

Retrieve the set of values that occur in matches for transition.

Returns:

the Set of all values or empty set if there are no matches

getAllValuesOftransition

public java.util.Set<TypedTransition> getAllValuesOftransition()

Retrieve the set of values that occur in matches for transition.

Returns:

the Set of all values or empty set if there are no matches

                                                                         throws ViatraQueryException

Returns:

the singleton instance of the query specification of this pattern

Throws:

ViatraQueryException - if the pattern definition could not be loaded
