Marker Handlers

Identifier:

com.ibm.xtools.emf.validation.core.markerHandlers

Since:

7.0.5

Description:

The marker handler extension point allows the contribution of an implementation which handles the creation and cleaning of markers for a given constraint and marker pair.

For constraint and marker pairs who do not have an associated marker handler, the default handling provided by the IValidationPresenter is used.
