Class Signal

java.lang.Object
  frysk.sys.Signal

All Implemented Interfaces:

Comparable

public class Signal
extends Object
implements Comparable

Host signal handling. Need to use native calls to find out the current host's signal values.

Method Summary

int	compareTo(Object o)
void	drain() Momentarialy sets the signal handler for Sig to SIGIGN so that any pending signals are discarded.
boolean	equals(Object o) Comparison operations; use intValue() so that sub-classing can provide a scratch int value.
static SignalSet	getHostSignalSet() Return the known host signals as a SignalSet.
int	hashCode() Hash on the Signal's intValue.
int	intValue() Return the signal's numeric value as an integer.
void	kill(ProcessIdentifier pid) Deliver SIG to process PID.
void	tkill(ProcessIdentifier lwp) Deliver SIGNAL to task (or thread) LWP.
String	toString() Dump the signal to a string.

Method Detail

toString

public String toString()

Dump the signal to a string. The format is "NAME(VALUE)".

Overrides:

toString in class Object

hashCode

public int hashCode()

Hash on the Signal's intValue.

Overrides:

hashCode in class Object

intValue

public int intValue()

Return the signal's numeric value as an integer.

equals

public boolean equals(Object o)

Comparison operations; use intValue() so that sub-classing can provide a scratch int value.

Overrides:

equals in class Object

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable

kill

public void kill(ProcessIdentifier pid)

Deliver SIG to process PID.

tkill

public final void tkill(ProcessIdentifier lwp)

Deliver SIGNAL to task (or thread) LWP.

drain

public final void drain()

Momentarialy sets the signal handler for Sig to SIGIGN so that any pending signals are discarded.

getHostSignalSet

public static SignalSet getHostSignalSet()

Return the known host signals as a SignalSet.
