IGrammarConstraintProvider.IConstraint (org.eclipse.xtext 2.30.0 API)

All Superinterfaces:

java.lang.Comparable<IGrammarConstraintProvider.IConstraint>

All Known Implementing Classes:

GrammarConstraintProvider.Constraint

Enclosing interface:

IGrammarConstraintProvider
```
public static interface IGrammarConstraintProvider.IConstraint
extends java.lang.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
  - getBody
```
IGrammarConstraintProvider.IConstraintElement getBody()
```
    Returns:
    
    the root of the tree of IGrammarConstraintProvider.IConstraintElement that defines this 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.
  - getName
```
java.lang.String getName()
```
    Returns:
    
    a name that is unique for a grammar and that aims to be human-readable.
  - getSimpleName
```
java.lang.String getSimpleName()
```
  - getType
```
org.eclipse.emf.ecore.EClass getType()
```
    Returns:
    
    This constraint only applies to EObjects of this type.
  - getContexts
```
java.util.List<ISerializationContext> getContexts()
```
  - getNfa
```
org.eclipse.xtext.util.formallang.Nfa<ISemanticSequencerNfaProvider.ISemState> getNfa()
```
