Listener Module The Listener module, located at x-oz://system/Listener, exports the class Listener.'class' with the following methods.
Methods
init(+NarratorO +ServeL) initializes a listener with a narrator and the label of a unary method. The listener creates a port, registers this with NarratorO, and creates a thread in which the ServeL method is applied to the port's stream.
close() undoes all effects of the init method: The server thread is terminated and the listener's port is unregistered.
getNarrator(?NarratorO) returns the narrator with which the listener's port is currently registered.
getPort(?Port) returns the associated port.
ErrorListener Module The ErrorListener module, located at x-oz://system/ErrorListener, exports the class ErrorListener.'class' with the following methods.
Methods
init(+NarratorO +ServeOneL <= unit ?VerboseL <= false)
reset()
setVerbosity(+L)
hasErrors(?B)
isActive(?B)
