  Returns QEncoder

Readonlyencoding

clone

• clone(): QEncoder

  Creates a new Q encoder with exactly the same state as this encoder.

  Returns QEncoder

  A new encoder with identical state.

estimateOutputLength

• estimateOutputLength(inputLength: number): number

  Estimates the number of bytes needed to encode the specified number of input bytes.

  Parameters

  • inputLength: number

    The input length.

  Returns number

  The estimated output length.

encode

• encode(
      input: Uint8Array,
      startIndex: number,
      length: number,
      output: Uint8Array,
  ): number

  Encodes the specified input into the output buffer.

  Parameters

  • input: Uint8Array

    The input buffer.

  • startIndex: number

    The starting index of the input buffer.

  • length: number

    The length of the input range.

  • output: Uint8Array

    The output buffer.

  Returns number

  The number of bytes written to the output buffer.

  Throws

  The input range is invalid or the output buffer is too small.

flush

• flush(
      input: Uint8Array,
      startIndex: number,
      length: number,
      output: Uint8Array,
  ): number

  Encodes the specified input into the output buffer and flushes internal state.

  Parameters

  • input: Uint8Array

    The input buffer.

  • startIndex: number

    The starting index of the input buffer.

  • length: number

    The length of the input range.

  • output: Uint8Array

    The output buffer.

  Returns number

  The number of bytes written to the output buffer.

  Throws

  The input range is invalid or the output buffer is too small.

reset

• reset(): void

  Resets the state of the encoder.

  Returns void
