Class 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:
        initialTransformations - A set of transformation URIs that shall be stored in the cache, might be empty.

    • Method Detail

      • 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.
        IllegalArgumentException - In case any of the transformations is already present in the cache.

      • get

        public Optional<QvtoModelTransformation> get​(URI transformationUri)
        Attempts to retrieve the QVTo transformation that is associated with the given URI from the cache.
        Parameters:
        transformationUri - A URI that points to a QVTo transformation.
        Returns:
        The TransformationData of the transformation, or null if it is not present in the cache.
        Throws:
        NullPointerException - In case the given URI is null.

        contains(URI)

      • remove

        @SafeVarargs
public final void remove​(URI... transformationUris)
        Removes the QVTo transformations specified by the given URIs from this cache, if present.
        Parameters:
        transformationUris - A set of URIs that point to QVTo transformations.
        Throws:
        NullPointerException - In case any of the given uris is null.

      • contains

        public boolean contains​(URI transformationUri)
        Gets whether the QVTo transformation which the given URI points to, is currently in the cache.
        Parameters:
        transformationUri - A URI that points to a QVTo transformation.
        Returns:
        true, iff the transformation is stored, false otherwise
        Throws:
        NullPointerException - In case the given URI is null.

      • getAll

        public Iterable<QvtoModelTransformation> getAll()
        Gets all the transformations, in terms of the respective TransformationData currently stored in this cache.
        Returns:
        An Iterable of all the stored transformations.

      • clear

        public void clear()
        Clears the cache, that is, all content is discarded.
