§Methods

process(chunk: Uint8Array, final: boolean): void protected

Processes a chunk and pushes to the output stream. You can override this method in a subclass for custom behavior, but by default this passes the data through. You must call this.ondata(err, chunk, final) at some point in this method.

@param chunk

The chunk to process

@param final

Whether this is the last chunk

push(chunk: Uint8Array, final?: boolean): void

Pushes a chunk to be added. If you are subclassing this with a custom compression algorithm, note that you must push data from the source file only, pre-compression.

@param chunk

The chunk to push

@param final

Whether this is the last chunk
