    • Method Detail

      • createIfOptional

        static Optionalish createIfOptional​(javax.lang.model.type.TypeMirror type)
        Returns an instance wrapping the given TypeMirror, or null if it is not any kind of Optional.
        Parameters:
        type - the TypeMirror for the original optional type, for example Optional<String>.

      • isOptional

        static boolean isOptional​(javax.lang.model.type.TypeMirror type)

      • getRawType

        public java.lang.String getRawType()
        Returns a string representing the raw type of this Optional. This will typically be just "Optional", but it might be "OptionalInt" or "java.util.Optional" for example.

      • getEmpty

        public java.lang.String getEmpty()
        Returns a string representing the method call to obtain the empty version of this Optional. This will be something like "Optional.empty()" or possibly "java.util.Optional.empty()". It does not have a final semicolon.

        This method is public so that it can be referenced as p.optional.empty from templates.
