  - isNoTypeExpectation
```
public boolean isNoTypeExpectation()
```
    Description copied from interface: ITypeExpectation
    
    Returns true if anything is allowed and no constraints are expected.
    
    Returns:
    
    true if anything is allowed and no constraints are expected.
  - getExpectedType
```
public LightweightTypeReference getExpectedType()
```
    Description copied from interface: ITypeExpectation
    
    Returns the expected type. The expected type may be not too concrete thus ITypeExpectation.getExpectedType() may return null or some sort of unresolved, specialized reference. If null is returned, clients may want to check ITypeExpectation.isNoTypeExpectation() or ITypeExpectation.isVoidTypeAllowed().
    
    Returns:
    
    the expected type. This may be null.
  - copyInto
```
public TypeExpectation copyInto(ITypeReferenceOwner referenceOwner)
```
