Enum ConformanceHint

    • Enum Constant Detail

      • PRIMITIVE_WIDENING

        public static final ConformanceHint PRIMITIVE_WIDENING

      • RAWTYPE_CONVERSION

        public static final ConformanceHint RAWTYPE_CONVERSION

      • LAMBDA_RAW_COMPATIBLE

        public static final ConformanceHint LAMBDA_RAW_COMPATIBLE

      • LAMBDA_VOID_COMPATIBLE

        public static final ConformanceHint LAMBDA_VOID_COMPATIBLE

      • LAMBDA_PARAMETER_COMPATIBLE

        public static final ConformanceHint LAMBDA_PARAMETER_COMPATIBLE

      • NO_IMPLICIT_RETURN

        public static final ConformanceHint NO_IMPLICIT_RETURN
        Indicates that the announced type is not an implicit return type. E.g. the type of a return expression is 'void' but this is not the implicit return type of the return expression itself. The return type was computed properly from the children of the return expression.

      • EXPLICIT_VOID_RETURN

        public static final ConformanceHint EXPLICIT_VOID_RETURN
        Used to indicate an explicit void return value

      • PROPAGATED_TYPE

        public static final ConformanceHint PROPAGATED_TYPE
        Indicates that the type of this expression is derived from a child which can provide better conformance information.

      • THROWN_EXCEPTION

        public static final ConformanceHint THROWN_EXCEPTION
        Indicates that the expression will definitely throw an exception.

      • UNKNOWN_TYPE_PARTICIPATED

        public static final ConformanceHint UNKNOWN_TYPE_PARTICIPATED
        Two types are considered compatible if one of the participants is the unknown type. This flag indicates this situation.

      • PREFERRED_LAMBDA_SUGAR

        public static final ConformanceHint PREFERRED_LAMBDA_SUGAR
        A method is overloaded with various function interfaces. The variant with a single-arg lambda is the prefered sugar version.

    • Method Detail

      • values

        public static ConformanceHint[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (ConformanceHint c : ConformanceHint.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ConformanceHint valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
