Method Detail

dependenciesInjected

public void dependenciesInjected()

All requested elements have been injected, so the feature may carry out additional initialisation. This method should be overridden by features that need to carry out additional initialisation.

Specified by:

dependenciesInjected in interface SentinelFeature

startFeature

public void startFeature(java.lang.Object trigger,
                java.lang.Object activity,
                javax.slee.ActivityContextInterface aci,
                java.util.Map<java.lang.String,ParameterValue> featureParameters)

kick off the feature

Specified by:

startFeature in interface SentinelFeature

Parameters:

trigger - a triggering context. The feature implementation must be able to cast this to a useful type for it to run

activity - the slee activity object this feature is related to (may be null)

aci - the activity context interface of the slee activity this feature is related to

featureParameters - parameters supplied in the run feature statement that caused this feature to be executed

abortFeature

public void abortFeature()

The feature should abandon execution and clear up any resources. This method should be overridden by features that need to implement shutdown behaviour and clean up allocated resources.

Specified by:

abortFeature in interface SentinelFeature

getSessionState

protected final SessionStateType getSessionState()

Returns:

the session state I have access to

getFacilities

protected final Facilities getFacilities()

Returns:

the object I use for access to common SLEE facilities

getTracer

protected final javax.slee.facilities.Tracer getTracer()

Returns:

the tracer I use for writing trace messages

getCaller

protected final EndpointType getCaller()

Returns:

the endpoint interface I use to interact with the sentinel core
