## Interface Bits

- All Known Implementing Classes:
    Bits.MatchAllBits, Bits.MatchNoBits, BitSet, FixedBitSet, MultiBits, SparseFixedBitSet

      public interface Bits

  Interface for Bitset-like structures.
  WARNING: This API is experimental and might change in incompatible ways in the next release.

    Nested Classes
    Modifier and Type | Interface and Description
    --- | ---
    `static class` | `Bits.MatchAllBits` Bits impl of the specified length with all bits set.
    `static class` | `Bits.MatchNoBits` Bits impl of the specified length with no bits set.

  - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static Bits[]` | `EMPTY_ARRAY`

  - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `get(int index)` Returns the value of the bit with the specified `index`.
    `int` | `length()` Returns the number of bits in this set

- - ### Field Detail

    - #### EMPTY_ARRAY

          static final Bits[] EMPTY_ARRAY

  - ### Method Detail

    - #### get

          boolean get(int index)

      Returns the value of the bit with the specified `index`.
      Parameters:
        `index` - index, should be non-negative and < `length()`. The result of passing negative or out of bounds values is undefined by this interface, just don't do it!
      Returns:
        `true` if the bit is set, `false` otherwise.

    - #### length

          int length()

      Returns the number of bits in this set
