Method Detail

newInstance

public abstract java.lang.Object newInstance()
                                      throws java.lang.Exception

Specified by:

newInstance in interface org.d_haven.mpool.ObjectFactory

Throws:

java.lang.Exception

dispose

public abstract void dispose(java.lang.Object object)
                      throws java.lang.Exception

setInstrumentableName

public final void setInstrumentableName(java.lang.String name)

Description copied from interface: Instrumentable

Sets the name for the Instrumentable. The Instrumentable Name is used to uniquely identify the Instrumentable during the configuration of the InstrumentManager and to gain access to an InstrumentableDescriptor through the InstrumentManager. The value should be a string which does not contain spaces or periods.

This value may be set by a parent Instrumentable, or by the InstrumentManager using the value of the 'instrumentable' attribute in the configuration of the component.

Specified by:

setInstrumentableName in interface Instrumentable

Parameters:

name - The name used to identify a Instrumentable.

getInstrumentableName

public final java.lang.String getInstrumentableName()

Description copied from interface: Instrumentable

Gets the name of the Instrumentable.

Specified by:

getInstrumentableName in interface Instrumentable

Returns:

The name used to identify a Instrumentable.

getInstruments

public final Instrument[] getInstruments()

Description copied from interface: Instrumentable

Obtain a reference to all the Instruments that the Instrumentable object wishes to expose. All sampling is done directly through the Instruments as opposed to the Instrumentable interface.

Specified by:

getInstruments in interface Instrumentable

Returns:

An array of the Instruments available for profiling. Should never be null. If there are no Instruments, then EMPTY_INSTRUMENT_ARRAY can be returned. This should never be the case though unless there are child Instrumentables with Instruments.

getChildInstrumentables

public final Instrumentable[] getChildInstrumentables()

Description copied from interface: Instrumentable

Any Object which implements Instrumentable can also make use of other Instrumentable child objects. This method is used to tell the InstrumentManager about them.

Specified by:

getChildInstrumentables in interface Instrumentable

Returns:

An array of child Instrumentables. This method should never return null. If there are no child Instrumentables, then EMPTY_INSTRUMENTABLE_ARRAY can be returned.

guessWorkInterfaces

protected static java.lang.Class[] guessWorkInterfaces(java.lang.Class clazz)

Get a list of interfaces to proxy by scanning through all interfaces a class implements and skipping invalid interfaces (as defined in #INVALID_INTERFACES).

Parameters:

clazz - the class

Returns:

the list of interfaces to proxy
