  • Constructor Details

    • IntsRefBuilder

      public IntsRefBuilder()
      Sole constructor.

  • Method Details

    • ints

      public int[] ints()
      Return a reference to the ints of this builder.

    • length

      public int length()
      Return the number of ints in this buffer.

    • setLength

      public void setLength(int length)
      Set the length.

    • clear

      public void clear()
      Empty this builder.

    • intAt

      public int intAt(int offset)
      Return the int at the given offset.

    • setIntAt

      public void setIntAt(int offset, int b)
      Set an int.

    • append

      public void append(int i)
      Append the provided int to this buffer.

    • grow

      public void grow(int newLength)
      Used to grow the reference array.

      In general this should not be used as it does not take the offset into account.

      NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

    • copyInts

      public void copyInts(int[] otherInts, int otherOffset, int otherLength)
      Copies the given array into this instance.

    • copyInts

      public void copyInts(IntsRef ints)
      Copies the given array into this instance.

    • copyUTF8Bytes

      public void copyUTF8Bytes(BytesRef bytes)
      Copy the given UTF-8 bytes into this builder. Works as if the bytes were first converted from UTF-8 to UTF-32 and then copied into this builder.

    • get

      public IntsRef get()
      Return a IntsRef that points to the internal content of this builder. Any update to the content of this builder might invalidate the provided ref and vice-versa.

    • toIntsRef

      public IntsRef toIntsRef()
      Build a new CharsRef that has the same content as this builder.

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object
