Method Detail

idleToBusy

void idleToBusy(java.lang.Object resource)

Is invoked on state transition from 'idle' to 'busy'.

You can code here some specific behavior.

Is invoked on state transition from 'busy' to 'idle'.

You can code here some specific behavior.

java.lang.Object toCreate(java.lang.String instanceId)
                          throws XmlBlasterException

Is invoked when a new resource is needed.

You need to create a new resource instance (e.g. a JDBC connection) and return it.

Returns:

A new Resource which will be managed

Throws:

XmlBlasterException

toErased

void toErased(java.lang.Object resource)
