Constructor Detail

EventDrivenCompoundDecoder

public EventDrivenCompoundDecoder(IDecoder<?,?>... decoders)

Constructs an event driven compound decoder with a chain of the specified decoders.

The decoder chain is organized in the following way:

 {data} -> decoder1 -> decoder2 -> ... -> decoderN -> {out}
 

Parameters:

decoders - the chain of decoders

Throws:

IllegalArgumentException - if the specified decoders have incompatible inbound or outbound types

IllegalStateException - if the param O is Void
