Method Detail

postmanaged

public void postmanaged()

Description copied from interface: Manageable

This method is called when the implementing adaptee has been managed either during post-registration of the corresponding adapter MBean or just after it is explicitly added to the adapter MBean during run-time.

Specified by:

postmanaged in interface Manageable

Overrides:

postmanaged in class Adaptee

unmanaged

public void unmanaged()
               throws Exception

Description copied from interface: Manageable

This method is called when the implementing adaptee is unmanaged either during pre-deregistration of the corresponding adapter MBean or just before it is explicitly removed from the adapter MBean during run-time.

Specified by:

unmanaged in interface Manageable

Overrides:

unmanaged in class Adaptee

Throws:

Exception - if the adaptee refused to be unmanaged.

getSchedulerName

public ObjectName getSchedulerName()

Description copied from interface: Schedulable

Gets the the scheduler of the schedulable.

Specified by:

getSchedulerName in interface Schedulable

Returns:

the object name of the scheduler or a query.

setSchedulerName

public void setSchedulerName(ObjectName scheduler)

Description copied from interface: Schedulable

Sets the scheduler of the schedulable. If it is not set, the default one will be used.

Note that it will be taken into use after next start.

Specified by:

setSchedulerName in interface Schedulable

Parameters:

scheduler - the object name of the scheduler or a query.

getPeriod

public long getPeriod()

Description copied from interface: Schedulable

Gets the execution period.

Specified by:

getPeriod in interface Schedulable

Returns:

the execution period in msecs.

setPeriod

public void setPeriod(long period)

Description copied from interface: Schedulable

Sets the execution period.

Note that it will be taken into use after next start.

Specified by:

setPeriod in interface Schedulable

Parameters:

period - the execution period in msecs.
