## Interface IndexDictionary.Builder

- All Known Implementing Classes:
    FSTDictionary.Builder
  Enclosing interface:
    IndexDictionary

      public static interface IndexDictionary.Builder

  Builds an immutable `IndexDictionary`.

- - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `add(BytesRef blockKey, long blockFilePointer)` Adds a [block key - block file pointer] entry to the dictionary.
    `IndexDictionary` | `build()` Builds the immutable `IndexDictionary` for the added entries.

- - ### Method Detail

    - #### add

          void add(BytesRef blockKey,
                   long blockFilePointer)
            throws IOException

      Adds a [block key - block file pointer] entry to the dictionary.

      The Uniform Split technique adds block keys in the dictionary. See `BlockReader` and `TermBytes` for more info about block key and minimal distinguishing prefix (MDP).

      All block keys are added in strictly increasing order of the block file pointers, this allows long encoding optimizations such as with `PositiveIntOutputs` for `FST`.

      Parameters:
        `blockKey` - The block key which is the minimal distinguishing prefix (MDP) of the first term of a block.
        `blockFilePointer` - Non-negative file pointer to the start of the block in the block file.
      Throws:
        `IOException`

    - #### build

          IndexDictionary build()
                         throws IOException

      Builds the immutable `IndexDictionary` for the added entries.
      Throws:
        `IOException`
