Examples of org.eclipse.core.databinding.AggregateValidationStatus

org.eclipse.core.databinding.AggregateValidationStatus
This class can be used to aggregate status values from a data binding context into a single status value. Instances of this class can be used as an observable value with a value type of {@link IStatus}, or the static methods can be called directly if an aggregated status result is only needed once. @since 1.0
