Returns:

The monitor control policy object.

setMonitorControl

public static void setMonitorControl(javax.realtime.MonitorControl policy)

Sets the default monitor behavior for object monitors used by synchronized statements and methods in the system. The type of the policy object determines the type of behavior. Conforming implementations must support priority ceiling emulation and priority inheritance for fixed priority preemptive threads.

Parameters:

policy - The new monitor control policy. If null nothing happens.

setMonitorControl

public static void setMonitorControl(java.lang.Object monitor,
                                     javax.realtime.MonitorControl monCtl)

Has the same effect as setMonitorControl(), except that the policy only affects the indicated object monitor.

Parameters:

monitor - The monitor for which the new policy will be in use. The policy will take effect on the first attempt to lock the monitor after the completion of this method. If null nothing will happen.
