Interface IGrammarConstraintProvider.IConstraint

All Superinterfaces:

Comparable<IGrammarConstraintProvider.IConstraint>

All Known Implementing Classes:

GrammarConstraintProvider.ActionConstraint, GrammarConstraintProvider.Constraint, GrammarConstraintProvider.RuleConstraint

Enclosing interface:

IGrammarConstraintProvider

public static interface IGrammarConstraintProvider.IConstraint
extends Comparable<IGrammarConstraintProvider.IConstraint>

One constraint defines all conditions one semantic object must comply with. A constraint is specific for one EClass and belongs to one or more contexts. The conditions defined by a constraint are represented by a tree of IGrammarConstraintProvider.IConstraintElement. This tree's root can be accessed by getBody().

Method Detail

getAssignments

IGrammarConstraintProvider.IConstraintElement[] getAssignments()

Returns:

a list of all assignments represented by this constraint. IGrammarConstraintProvider.IConstraintElement.getAssignmentID() returns an Assignment's index in this list. The order of the list reflects the order of the assignments in the constraint. Assignments are IGrammarConstraintProvider.IConstraintElements with IGrammarConstraintProvider.IConstraintElement.getType() == ASSIGNED_*

getBody

IGrammarConstraintProvider.IConstraintElement getBody()

Returns:

the root of the tree of IGrammarConstraintProvider.IConstraintElement that defines this constraint.

getElements

IGrammarConstraintProvider.IConstraintElement[] getElements()

Returns:

a list of all elements represented by this constraint. This is a flattened version of the tree returned by getBody(). IGrammarConstraintProvider.IConstraintElement.getElementID() returns an Assignment's index in this list. The order of the list reflects the order of the elements in the constraint.

getFeatures

IGrammarConstraintProvider.IFeatureInfo[] getFeatures()

Returns:

a list of IGrammarConstraintProvider.IFeatureInfo for all EStructuralFeatures from the EClass returned by getType() that have an assignment if this constraint. If there is no assignment for an EStructuralFeature in this constraint, the array's item is null.

getSingleAssignementFeatures

Iterable<IGrammarConstraintProvider.IFeatureInfo> getSingleAssignementFeatures()

getMultiAssignementFeatures

Iterable<IGrammarConstraintProvider.IFeatureInfo> getMultiAssignementFeatures()

getName

String getName()

Returns:

a name that is unique for a grammar and that aims to be human-readable.

getSimpleName

String getSimpleName()

getType

org.eclipse.emf.ecore.EClass getType()

Returns:

This constraint only applies to EObjects of this type.
