Throws:

org.apache.avalon.framework.component.ComponentException

Specified by:

hasComponent in interface org.apache.avalon.framework.component.ComponentManager

release

setInstrumentManager

public void setInstrumentManager(org.apache.excalibur.instrument.InstrumentManager instrumentManager)

Deprecated.

Sets the InstrumentManager for child components. Can be for special purpose components, however it is used mostly internally.

Specified by:

setInstrumentManager in interface org.apache.excalibur.instrument.InstrumentManageable

Parameters:

instrumentManager - The InstrumentManager for the component to use.

setInstrumentableName

public void setInstrumentableName(java.lang.String name)

Deprecated.

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 org.apache.excalibur.instrument.Instrumentable

Parameters:

name - The name used to identify a Instrumentable.

getInstrumentableName

public java.lang.String getInstrumentableName()

Specified by:

getInstruments in interface org.apache.excalibur.instrument.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.

Deprecated.

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