subset abstract method

InputStream subset({
  1. int? position,
  2. int? length,
  3. int? bufferSize,
})

Return a InputStream to read a subset of this stream. It does not move the read position of this stream. position is specified relative to the start of the buffer. If position is not specified, the current read position is used. If length is not specified, the remainder of this stream is used. If bufferSize is provided, and this is an InputFileStream, the returned InputStream will get its own FileBuffer with the given bufferSize, otherwise it will share the FileBuffer of this InputFileStream.

Implementation

InputStream subset({int? position, int? length, int? bufferSize});
