invoke

public Task invoke(Task task,
                   Properties props,
                   com.infoengine.log.ServiceWriter log)
            throws WebjectServiceException,
                   WTException

This method does not appear in the Rose model. It overrides the invoke method of wt.adapter.WebjectDelegateTemplate to check the name under which the webject delegate is called. If it is called as "Query-Objects", it checks for a MODE parameter. If MODE is specifed as COMPATIBILITY, control is transferred to wt.adapter.QueryObjects. Otherwise, control is passed to the invoke method of the superclass.

Specified by:

invoke in interface WebjectDelegate

Overrides:

invoke in class WebjectDelegateTemplate

Parameters:

task -

props -

log -

Returns:

com.infoengine.object.factory.Task

Throws:

WebjectServiceException

WTException
