Method Detail

isTransient

public boolean isTransient(org.eclipse.emf.ecore.EObject owner,
                           org.eclipse.emf.ecore.EStructuralFeature feature,
                           int index)

Description copied from interface: ITransientValueService

Decides whether a value should be serialized. If !feature.isMany() or !isMixedList(feature), this method is only called once for each feature. In this case, index is < 0. If feature.isMany() and isMixedList(feature), this method is called for each of the feature's values. Attention: Values marked transient are only not serialized when they are optional in the grammar. Example: Rule1: transientF=INT normalF=INT; In this case, the grammar requires to serialize transientF to produce a valid DSL-script. Attention: Think of how many times the serializer calls this method and supply a fast implementation. The serializer tries to avoid multiple calls to this method using the same parameters, but depending on the grammar and the model, it may happen.

Parameters:

owner - The EObject holding the feature's value

feature - the to-be-checked feature

index - the index in the list for multi value features

Returns:

true, if the feature's value(s) should NOT be serialized
