                                                                RestrictionEvaluationException

Turns an ECore expression into a version restriction.

Parameters:

name - the name of the element being processed

expr - the expression to be turned into a version restriction (may be null but then the result will also be null).

translator - the expression translator (may be null but then the result will also be null)

context - the current type context (may be null but then the result will also be null)

handler - an optional message handler (may be null)

Returns:

the related version restriction (may be null)

Throws:

TranslatorException - in case of translation problems

RestrictionEvaluationException - in case of problems while creating the restriction

processConflict

public static ProjectImport processConflict(de.uni_hildesheim.sse.ivml.ConflictStmt conflictStmt)
                                     throws TranslatorException

Processes a conflict statement including import restrictions. In case of errors the respective element is not added to the resulting project. Anyway, no restriction expressions are produced!

Parameters:

conflictStmt - the conflict statement

Returns:

the related IVML model instance

Throws:

TranslatorException - in case of semantic errors

processConflict

public static ProjectImport processConflict(de.uni_hildesheim.sse.ivml.ConflictStmt conflictStmt,

                                            TypeContext context)
                                     throws TranslatorException

Parameters:

conflictStmt - the conflict statement

translator - the expression translator (may be null but then no restriction expressions are produced)

context - the current type context (may be null but then no restriction expressions are produced)

Returns:

the related IVML model instance

Throws:

TranslatorException - in case of semantic errors

                                   throws TranslatorException

Processes an import statement including import restrictions. In case of errors the respective element is not added to the resulting project. Anyway, no restriction expressions are produced!

Parameters:
