Class ModelTransformationCache

java.lang.Object
org.palladiosimulator.simulizar.reconfiguration.qvto.util.ModelTransformationCache
public class ModelTransformationCache extends Object
This cache implementation is used to store QVTo transformations (in terms of TransformationData objects) that can be executed by QVTo executors during reconfigurations. To store a transformation in the cache, its corresponding URI is used as tag.

      @SafeVarargs public ModelTransformationCache(URI... initialTransformations)
      Initializes a new instance of the ModelTransformationCache class.
      Parameters:

    • store

      @SafeVarargs public final void store(URI... transformationUris)
      Stores the QVTo transformations specified by the given URIs in the cache.
      Parameters:
      transformationUris - A set of URIs that point to QVTo transformations.
      Throws:
      NullPointerException - In case transformationUris == null.
