• getPersistentFeatures

  @Deprecated public static List<EStructuralFeature> getPersistentFeatures(EList<EStructuralFeature> eFeatures)

  Deprecated.

  This method is expensive and will be removed in the future.

  Since:

  3.0

  • isPersistent(EStructuralFeature)

• isPersistent

  public static boolean isPersistent(EStructuralFeature feature)

  Returns true if CDO considers the given feature persistent, false otherwise.

  Note that CDO persistent is not identical to non-transient because that can be overridden with CDO_ANNOTATION_KEY_PERSISTENT. Another reason for possible deviations is that CDO considers transient references persistent if they have a persistent opposite.

  Note also that the checks for the aforementioned deviations from EStructuralFeature.isTransient() make this method somewhat expensive. Whenever possible CDOClassInfo.isPersistent() should be called instead.

• getCollectionLoadingChunkConfig

  public static CDOCollectionLoadingConfig.ChunkConfig getCollectionLoadingChunkConfig(EModelElement modelElement)

  Returns the explicitly configured collection-loading dimensions of an EMF model element.

  Invalid details are ignored independently and logged as warnings. A null result means that the element does not contain a valid explicitly configured dimension.

  Parameters:

  modelElement - the model element to inspect

  Returns:

  the explicit chunk configuration, or null

• isDynamicEPackage

  public static boolean isDynamicEPackage(Object value)

• getParentURI

  public static String getParentURI(EPackage ePackage)

• registerPackage

  public static void registerPackage(EPackage ePackage, EPackage.Registry... packageRegistries)

• getEPackageBytes

  public static byte[] getEPackageBytes(EPackage ePackage, boolean zipped, EPackage.Registry packageRegistry)

• createEPackage

  public static EPackage createEPackage(String uri, byte[] bytes, ResourceSet resourceSet, boolean lookForResource)

  Creates an EPackage from the given byte array by loading it into a resource in the given resource set.

  If lookForResource is true, then an attempt is made to find an existing resource with the given URI before creating a new one.

  The method automatically detects whether the byte array is zipped.

  Note that the byte array is not copied, so it must not be modified while the resource is in use.

  Since:

  4.27

  • createEPackage(String, byte[], boolean, ResourceSet, boolean)

• createEPackage

  public static EPackage createEPackage(String uri, byte[] bytes, boolean zipped, ResourceSet resourceSet, boolean lookForResource)

  Creates an EPackage from the given byte array by loading it into a resource in the given resource set.

  If lookForResource is true, then an attempt is made to find an existing resource with the given URI before creating a new one.

  If the byte array is zipped, then set zipped to true.

  Note that the byte array is not copied, so it must not be modified while the resource is in use.
