requireFeature was the old field in the asset which didn t contain tolerates information . The new field is requireFeatureWithTolerates and for the moment both fields are being maintained as older assets in the repository will only have the older field . When older assets are being written to the data from the older field needs to be copied to the new field to ensure both are consistent . The write will then write to both fields

This method will execute an immediate read The immediate read will issue a read to the TCP Channel and immediately return with whatever can fit in the buffers This will only ever be called after we had read the 1 byte from the isReady or initialRead methods . As such we will allocate a buffer and add in the 1 byte . This method should always return at least 1 byte even if the read fails since we have already read that byte

Allocate the buffer size we need and then pre - configure the buffer to prepare it to be read into Once it has been prepared set the buffer to the TCP Channel

This checks if we have already had an exception thrown . If so it just rethrows that exception This check is done before any reads are done

This method triggers the initial read on the connection or the read for after the ReadListener . onDataAvailable has run The read done in this method is a forced async read meaning it will always return on another thread The provided callback will be called when the read is completed and that callback will invoke the ReadListener logic .

|
Called after the initial read is completed . This will set the first read flag to false get the buffer from the TCP Channel and post configure the buffer . Without this method we would lose the first byte we are reading
