Method Details

getContributionId

public String getContributionId(EventHandler contrib)

Description copied from class: ContributionFragmentRegistry

Returns the contribution ID given the contribution object

Specified by:

getContributionId in class ContributionFragmentRegistry<EventHandler>

contributionUpdated

public void contributionUpdated(String id,
 EventHandler handler,
 EventHandler newOrigContrib)

Description copied from class: ContributionFragmentRegistry

Adds or updates a contribution.

If the contribution doesn't yet exists then it will be added, otherwise the value will be updated. If the given value is null the existing contribution must be removed.

The second parameter is the contribution that should be updated when merging, as well as stored and used. This usually represents a clone of the original contribution or a merge of multiple contribution fragments. Modifications on this object at application level will be lost on next method call on the same object id: modifications should be done in the ContributionFragmentRegistry.merge(Object, Object) method.

The last parameter is the new contribution object, unchanged (original) which was neither cloned nor merged. This object should never be modified at application level, because it will be used each time a subsequent merge is done. Also, it never should be stored.

Specified by:

contributionUpdated in class ContributionFragmentRegistry<EventHandler>

Parameters:

id - - the id of the contribution that needs to be updated

handler - the updated contribution object that

newOrigContrib - - the new, unchanged (original) contribution fragment that triggered the update.

contributionRemoved

public void contributionRemoved(String id,
 EventHandler handler)

Description copied from class: ContributionFragmentRegistry
