constructor

new EntityDecoder(decodeTree, emitCodePoint, errors?): EntityDecoder
Parameters
- decodeTree: Uint16Array
  The tree used to decode entities.
- emitCodePoint: ((cp: number, consumed: number) => void)
  The function that is called when a codepoint is decoded.
  
  For multi-byte named entities, this will be called multiple times, with the second codepoint, and the same consumed value.
  
  Param: codepoint
  The decoded codepoint.
  
  Param: consumed
  The number of bytes consumed by the decoder.
  - - (cp, consumed): void
    - Parameters
      cp: number
      consumed: number
      Returns void
- Optionalerrors: EntityErrorProducer
  An object that is used to produce errors.
Returns EntityDecoder
- Defined in decode.ts:90

Methods

end

end(): number
Signal to the parser that the end of the input was reached.

Remaining data will be emitted and relevant errors will be produced.

Returns number
The number of characters consumed.
- Defined in decode.ts:429

startEntity

startEntity(decodeMode): void
Resets the instance to make it reusable.
Parameters
- decodeMode: DecodingMode
Returns void
- Defined in decode.ts:127

write

write(input, offset): number
Write an entity to the decoder. This can be called multiple times with partial entities. If the entity is incomplete, the decoder will return -1.

Mirrors the implementation of getDecoder, but with the ability to stop decoding if the entity is incomplete, and resume when the next string is written.
Parameters
- input: string
  The string containing the entity (or a continuation of the entity).
- offset: number
  The offset at which the entity begins. Should be 0 if this is not the first call.
Returns number
The number of characters that were consumed, or -1 if the entity is incomplete.
- Defined in decode.ts:147
