Class BatchTransformationRule<Match extends IPatternMatch,Matcher extends ViatraQueryMatcher<Match>>

java.lang.Object

org.eclipse.viatra.transformation.runtime.emf.rules.batch.BatchTransformationRule<Match,Matcher>

All Implemented Interfaces:

ITransformationRule<Match,Matcher>

Direct Known Subclasses:

DSETransformationRule

public class BatchTransformationRule<Match extends IPatternMatch,Matcher extends ViatraQueryMatcher<Match>>
extends java.lang.Object
implements ITransformationRule<Match,Matcher>

Wrapper class for transformation rule definition to hide EVM specific internals. Subclasses can simply override the abstract precondition and model manipulation methods.

Field Summary

Fields

Modifier and Type	Field and Description
protected java.lang.String	ruleName
static ActivationLifeCycle	STATEFUL_RULE_LIFECYCLE Lifecycle for a rule that stores the list of fired activations; thus effectively forbids re-firing the same activation.
static ActivationLifeCycle	STATELESS_RULE_LIFECYCLE Lifecycle for a rule that does not store the list of fired activations; thus allows re-firing the same activation again.

Constructor Summary

Constructors

Modifier	Constructor and Description
protected	BatchTransformationRule()
	BatchTransformationRule(BatchTransformationRule<Match,Matcher> rule, EventFilter<Match> filter)
	BatchTransformationRule(java.lang.String rulename, IQuerySpecification<Matcher> matcher, ActivationLifeCycle lifecycle, IMatchProcessor<Match> action)
	BatchTransformationRule(java.lang.String rulename, IQuerySpecification<Matcher> matcher, ActivationLifeCycle lifecycle, IMatchProcessor<Match> action, EventFilter<Match> filter)

Method Summary

Modifier and Type	Method and Description
IMatchProcessor<Match>	getAction() Return an IMatchProcessor representing the model manipulation executed by the rule.
EventFilter<? super Match>	getFilter() Returns the event filter set up for this rule; if no specific filter is set up, an dedicated empty filter is returned
java.lang.String	getName()
IQuerySpecification<Matcher>	getPrecondition() Returns the query specification representing the pattern used as a precondition.
RuleSpecification<Match>	getRuleSpecification() Returns a RuleSpecification that can be added to a rule engine.

STATEFUL_RULE_LIFECYCLE

public static final ActivationLifeCycle STATEFUL_RULE_LIFECYCLE

Lifecycle for a rule that stores the list of fired activations; thus effectively forbids re-firing the same activation.
