Method Details
abstract def receive[R](f : PartialFunction[Msg, R]) : R
Receives a message from this InputChannel.
Parameters
f - a partial function with message patterns and actions
Returns
result of processing the received value
abstract def receiveWithin[R](msec : Long)(f : PartialFunction[Any, R]) : R
Receives a message from this InputChannel within a certain time span.
Parameters
msec - the time span before timeout
f - a partial function with message patterns and actions
Returns
result of processing the received value
abstract def react(f : PartialFunction[Msg, Unit]) : Nothing
Receives a message from this InputChannel.

This method never returns. Therefore, the rest of the computation has to be contained in the actions of the partial function.

Parameters
f - a partial function with message patterns and actions
abstract def reactWithin(msec : Long)(f : PartialFunction[Any, Unit]) : Nothing
Receives a message from this InputChannel within a certain time span.

This method never returns. Therefore, the rest of the computation has to be contained in the actions of the partial function.

Parameters
msec - the time span before timeout
f - a partial function with message patterns and actions
abstract def ? : Msg
Receives the next message from this Channel.
