Class Helpers

java.lang.Object

org.eclipse.incquery.runtime.api.impl.BasePatternGroup

org.eclipse.incquery.runtime.api.impl.BaseGeneratedPatternGroup

org.eclipse.incquery.viewmodel.traceability.patterns.Helpers

All Implemented Interfaces:

IQueryGroup

public final class Helpers
extends BaseGeneratedPatternGroup

A pattern group formed of all patterns defined in helpers.eiq.

Use the static instance as any org.eclipse.incquery.runtime.api.IPatternGroup, to conveniently prepare an EMF-IncQuery engine for matching all patterns originally defined in file helpers.eiq, in order to achieve better performance than one-by-one on-demand matcher initialization.

From package org.eclipse.incquery.viewmodel.traceability.patterns, the group contains the definition of the following patterns:

• emptyTrace
• traceTargets
• trace2target
• trace2param
• trace2object
• param2target
• trace
