Method Details

appendChangeNoticeCondition

protected abstract void appendChangeNoticeCondition(QuerySpec querySpec,
 int changeIdx)
                                             throws QueryException

Appends the condition that determines whether a change notice is pending. By default, the change notice is pending if the life cycle state matches a state defined in the property wt.change2.pendingOrderStates from wt.properties. The current implementation would append the following condition phrase to the specified query spec, where A0 is the changeIdx(the table index for the change Item):

 A0.statestate = 'IMPLEMENTATION'
 

A custom event handler should implement this method to define the conditions that make a change notice pending.

Supported API: true

Overrides:

appendChangeNoticeCondition in class ChangeStatusEventHandler

Parameters:

querySpec - - query spec to which the condition need to be appended

changeIdx - - table index for the change notice

Throws:

WTException

QueryException

appendChangeRequestCondition

protected abstract void appendChangeRequestCondition(QuerySpec querySpec,
 int changeIdx)
                                              throws QueryException

Appends the condition that determines whether a change request is pending. By default, the change request is pending if the life cycle state matches a state defined in the property wt.change2.pendingRequestStates from wt.properties. The current implementation would append the following condition phrase to the specified query spec, where A0 is the changeIdx(the table index for the change Item):

 A0.statestate = 'IMPLEMENTATION'
 

A custom event handler should implement this method to define the conditions that make a change request pending.

Supported API: true

Parameters:

querySpec - - query spec to which the condition need to be appended

changeIdx - - table index for the change request

Throws:
