## Interface LowLevelIndexRepository

- All Known Implementing Classes:
    FSIndexRepositoryImpl

      public interface LowLevelIndexRepository

  Low-level index repository access. Provides access to low-level indexes.

  Use `LowLevelCAS.ll_getIndexRepository()` to gain access to an object of this type.

- - ### Method Detail

    - #### ll_getIndex

          LowLevelIndex ll_getIndex(String indexName)

      Get an index by its name.
      Parameters:
        `indexName` - The name of the index.
      Returns:
        The corresponding index, or `null` if no such index exists.

    - #### ll_getIndex

          LowLevelIndex ll_getIndex(String indexName,
                                    int typeCode)

      Get an index by a name and type. The type must be a subtype of the index's type. Note that there is no special checked version of this method, the type parameters are always checked.
      Parameters:
        `indexName` - The name of the index.
        `typeCode` - The code of the desired subtype.
      Returns:
        The corresponding index, or `null` if no such index exists.
      Throws:
        `LowLevelException` - If the type code argument is not a valid type code.

    - #### ll_addFS

          void ll_addFS(int fsRef)

      Add a FS reference to all appropriate indexes in the repository.
      Parameters:
        `fsRef` - The FS reference to be added to the repository. If `fsRef` is not a valid FS reference, the subsequent behavior of the system is undefined.

    - #### ll_addFS

          void ll_addFS(int fsRef,
                        boolean doChecks)

      Add a FS reference to all appropriate indexes in the repository.
      Parameters:
        `fsRef` - The FS reference to be added to the repository. If `fsRef` is not a valid FS reference, the subsequent behavior of the system is undefined.
        `doChecks` - Check if the FS reference argument is a valid reference.

    - #### ll_removeFS

          void ll_removeFS(int fsRef)

      Remove a FS reference from all indexes in the repository. Note that this only removes the reference from the index repository, it does not free memory on the heap.
      Parameters:
        `fsRef` - The FS reference to be removed from the indexes.
