Class ResourceSetPartition

java.lang.Object
de.uka.ipd.sdq.workflow.mdsd.blackboard.ResourceSetPartition
public class ResourceSetPartition extends Object
Implementation of a blackboard partition based on EMF Resource Sets. Each partition has a resource set configured for the given EPackages. It can load a set of model resources. Inter-Model links are resolved up to the boundaries of the underlying resource set

  • Field Details

    • rs

      protected ResourceSet rs
      Common EMF resource set for all models in this partition.

  • Constructor Details

    • ResourceSetPartition

      public ResourceSetPartition()

  • Method Details

    • getResourceSet

      public ResourceSet getResourceSet()
      Gets the resource set.
      Returns:
      Returns the internal used resource set of this blackboard partition

    • initialiseResourceSetEPackages

      public void initialiseResourceSetEPackages(EPackage[] ePackages)
      Initialize the EPackages of the models to be stored in this blackboard partition.
      Parameters:
      ePackages - The list of EPackages which form the meta-model of the model stored in this model partition

    • loadModel

      public Resource loadModel(URI modelURI)
      Load the model with the given URI into this blackboard partition.
      Parameters:
      modelURI - The URI of the model to be loaded
      Returns:
      The loaded resource

    • getContents

      public List<EObject> getContents(URI modelURI)
      Returns all top level EObjects of the given model stored under the given URI. The model has to be created first.
      Parameters:
      modelURI - The model URI
      Returns:
      All top level elements of the model. Empty list if none have been found.

    • getFirstContentElement

      public EObject getFirstContentElement(URI modelURI)
      Returns the first top level EObject of the given model stored under the given URI. The model has to be created first and it has to have at least one top level element
      Parameters:
      modelURI - The model URI
      Returns:
      The first top level element of the model

    • loadModel

      @Deprecated public Resource loadModel(String modelURI)
      Deprecated.
      Use loadModel taking a URI instead
      Load the model with the given URI into this blackboard partition.
      Parameters:
      modelURI - The URI of the model to be loaded
      Returns:
      The loaded resource

    • resolveAllProxies

      public void resolveAllProxies()
      Resolve all model proxies, i.e., load all dependent models.

    • setContents

      public void setContents(URI modelID, List<EObject> newContents)
      Replaces the contents of the given model with newContents.
      Parameters:
      modelID - The model extent whose contents get replaced
      newContents - The new contents

    • setContents

      public void setContents(URI modelID, EObject newContents)
      Replaces the contents of the given model with newContents.
      Parameters:
      modelID - The model extent whose contents get replaced
      newContents - The new contents, single object

    • hasModel

      public boolean hasModel(URI modelURI)
      Determines if the Resource referenced by the parameter contains an EMF model.
      Parameters:
      modelURI - URI of the Resource.
      Returns:
      true if, and only if, an EMF model is contained.

    • storeAllResources

      public void storeAllResources() throws IOException
      Stores all resources in the resource set.
      Throws:
      IOException - If saving leads to I/O-Errors.

    • storeAllResources

      public void storeAllResources(Map<String,Object> saveOptions) throws IOException
      Stores all resources in the resource set.
      Parameters:
      saveOptions - Save options to use
      Throws:
      IOException - IOException If saving leads to I/O-Errors.

    • getElement

      public <T extends EObject> List<T> getElement(EClass targetType)

      Type Parameters:
      T - the generic type
      Parameters:
      targetType - the target type
      Returns:
      The list of found root elements. Empty list if none have been found.

    • hasElement

      public boolean hasElement(EClass targetType)
      Helper to determine whether root objects of a specified class exist.
      Parameters:
      targetType - the target type
      Returns:
