Method Details
- invariant
  
  public static FunctionReturnTypeResolver invariant(BasicType<?> invariantType)
  
  A resolver that defines an invariant result type. E.g. `substring` always returns a String. Note however that to account for attribute converters and such, this resolver allows the context-implied expression type to be the return type so long as the Java types are compatible.
