-------------------------------------
Resolution: Fixed
> Retrofit WarningListener in a more generic EventListener
> --------------------------------------------------------
>
> Key: SIS-421
> URL: https://issues.apache.org/jira/browse/SIS-421
> Project: Spatial Information Systems
> Issue Type: Improvement
> Components: Storage, Utilities
> Affects Versions: 0.8
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Major
> Fix For: 1.0
>
>
> {{DataStore}} in SIS 1.0-SNAPSHOT (June 2018) have two kind of listeners:
> * The {{org.apache.sis.util.logging}} package defines a {{WarningListener}}
> interface, together with a {{WarningListeners}} helper class.
> * The {{org.apache.sis.storage.event}} package defines a {{ChangeListener}}
> interface, together with {{ChangeEvent}} class. The intent is to have
> different {{ChangeEvent}} subtypes for e.g. structural changes, content
> changes, _etc._
> We should consider renaming the later as {{StoreListener}} and
> {{StoreEvent}}, and define a {{WarningEvent}} class. The old
> {{WarningListener}} could be replaced by this new mechanism. The intent is to
> avoid having two listener mechanism in parallel in data stores.
> It seems that {{WarningListener}} are currently used only in {{DataStore}},
> with the exception of {{org.apache.sis.metadata.sql}} package. So even if
> {{WarningEvent}} become storage-specific, it may not be a big issue.
