Interface JFSIndexRepository

All Known Implementing Classes:
JFSIndexRepositoryImpl
public interface JFSIndexRepository
Provides the same function as the FSIndexRepository except that the variants that take a "type" argument take type arguments obtainable easily from the JCas type.

  • Method Details

    • getIndex

      <T extends TOP> FSIndex<T> getIndex(String label)
      Retrieve an index according to a label.
      Type Parameters:
      T - the Java class corresponding to the top most type defined by this index
      Parameters:
      label - The name of the index.
      Returns:
      The index with the name label, or null if no such index is defined.

    • getIndex

      <T extends TOP> FSIndex<T> getIndex(String label, int type)
      Retrieve an index according to a label and a type. The type is used to narrow down the index of a more general type to a more specific one.
      Type Parameters:
      T - the Java class corresponding to the type
      Parameters:
      label - The name of the index
      type - A subtype of the type of the index, written as Foo.type
      Returns:
      The specified index, or null if an index with that name doesn't exist, or it exists but type is not a subtype of the index's type.

    • getAnnotationIndex

      AnnotationIndex<Annotation> getAnnotationIndex()
      Get the standard annotation index.
      Returns:
      The standard annotation index.

    • getAnnotationIndex

      <T extends Annotation> AnnotationIndex<T> getAnnotationIndex(int type)
      Get the standard annotation index restricted to a specific annotation type.
      Type Parameters:
      T - the Java class corresponding to type
      Parameters:
      type - The annotation type the index is restricted to, written as Foo.type
      Returns:
      The standard annotation index, restricted to type.

    • getLabels

      Iterator<String> getLabels()
      Get all labels for all indexes.
      Returns:
      All labels.

    • getIndexes

      Iterator<FSIndex<TOP>> getIndexes()
      Get all indexes in this repository.
      Returns:
      All indexes.

    • getFSIndexRepository

      FSIndexRepository getFSIndexRepository()
      Get the underlying FSIndexRepository associated with this JFSIndexRepository.
      Returns:
      The associated FSIndexRepository.

    • getAllIndexedFS

      <T extends TOP> FSIterator<T> getAllIndexedFS(Type aType)
      Gets an iterator over all indexed FeatureStructures of the specified Type (and any of its subtypes).

      Limitation: If there are no sorted or bag indexes defined for this type, but there is more than one set index defined, then this method will only return the contents of one of these set indexes (chosen arbitrarily). Generics: The returned Java cover class may not be a JCas one.

      Type Parameters:
      T - the Java Class corresponding to aType
      Parameters:
      aType - The type
      Returns:
      An iterator that returns all indexed FeatureStructures of type aType, in no particular order.

    • getAllIndexedFS

      <T extends TOP> FSIterator<T> getAllIndexedFS(int aType)
      Gets an iterator over all indexed FeatureStructures of the specified Type (and any of its subtypes).

      Limitation: If there are no sorted or bag indexes defined for this type, but there is more than one set index defined, then this method will only return the contents of one of these set indexes (chosen arbitrarily). Generics: The returned Java cover class may not be a JCas one.

      Type Parameters:
      T - the Java Class corresponding to aType
      Parameters:
      aType - The JCas unique type id obtained by doing MyJCasClass.type
      Returns:
      An iterator that returns all indexed FeatureStructures of type aType, in no particular order.
