Class SignalSet

java.lang.Object
  frysk.sys.SignalSet

public final class SignalSet
extends Object

A Signal Set, corresponds to sigset_t.

Constructor Summary

SignalSet()
Create an empty signal set.

SignalSet(Signal sig)
Create a SigSet containing the single signal.

SignalSet(Signal[] sigs)
Create a SigSet containing the signals in the array.

Method Summary

SignalSet	add(Signal sig) Add sigNum to the SignalSet; return this.
SignalSet	add(Signal[] sigs) Add the array of signals to the SignalSet; return this.
SignalSet	blockProcMask() Block this SignalSet's signals; return this.
SignalSet	blockProcMask(SignalSet oldSet) Block this SignalSet's signals; return the previous signal set in oldSet; return this.
boolean	contains(Signal sig) Does this SignalSet contain sigNum (the underlying code uses sigismember, the name contains is more consistent with java.
SignalSet	empty() Empty the signal set; return this.
SignalSet	fill() Fill the signal set; return this.
SignalSet	getPending() Set to the set of pending signals; return this
SignalSet	getProcMask() Get the current process signal mask; return this.
SignalSet	remove(Signal sig) Remove Signal from the SignalSet (the underlying code uses sigdelset, the name remove is more consistent with java); return this.
SignalSet	setProcMask() Set the process signal mask to this SignalSet's signals; return this.
SignalSet	setProcMask(SignalSet oldSet) Set the thread's signal mask to this SignalSet's signals; return the previous signal set in oldSet.
int	size() The number of elements in the set.
SignalSet	suspend() Suspend the thread, unblocking signals in SignalSet; return this.
Signal[]	toArray() As an array.
String	toString() As a string.
SignalSet	unblockProcMask() Unblock this SignalSet's signals; return this.
SignalSet	unblockProcMask(SignalSet oldSet) Unblock this SignalSet's signals; return the previous signal set in oldSet; return this.
