All Implemented Interfaces:

Serializable

Enclosing class:

RASM

Deprecated. Use IsAvailable

public static class RASM.IsAvailable

extends Instruction

Test channel for availability.

Places on the stack whether an input channel, chanId, has a request waiting to be serviced. This does not cause the thread to become descheduled (isAvailable is rather like chan_ready in LARD) and can be used safely on the same channel multiple times in the same activation of a thread) but may trigger slightly different behaviour in the scheduler upon execution if the next sleep instruction under certain circumstances (i.e. where the scheduler is executing threads in a backwards direction, this instruction will always return a false value, and will cause the thread to be scheduled in the reverse direction when the next sleep is encountered instead of simply not being scheduled at all until another thread requests it.)

chanId boolean
