  - getNodeType
```
SqmExpressible<T> getNodeType()
```
    The expression's type.
    Can change as a result of calls to applyInferableType(org.hibernate.query.sqm.SqmExpressible<?>)
    
    Specified by:
    
    getNodeType in interface SqmTypedNode<T>
  - applyInferableType
```
@Internal
void applyInferableType(SqmExpressible<?> type)
```
    Used to apply type information based on the expression's usage within the query.
    
    API Note:
    
    The SqmExpressible type parameter is dropped here because the inference could technically cause a change in Java type (i.e. an implicit cast)
