Enum Constant Detail

NOT_SUPPORTED

public static final MessageBodyOperator.PredicateResult NOT_SUPPORTED

Requested type not supported.

COMPATIBLE

public static final MessageBodyOperator.PredicateResult COMPATIBLE

Requested type is compatible with this operator, but it is not exact match.

SUPPORTED

public static final MessageBodyOperator.PredicateResult SUPPORTED

Requested type is supported by that specific operator.

Method Detail

values

public static MessageBodyOperator.PredicateResult[] 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 (MessageBodyOperator.PredicateResult c : MessageBodyOperator.PredicateResult.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MessageBodyOperator.PredicateResult valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

supports

public static MessageBodyOperator.PredicateResult supports(Class<?> expected,
                                                           GenericType<?> actual)

Whether handled class is supported. Method Class.isAssignableFrom(Class) is invoked to verify if class under expected parameter is supported by by the class under actual parameter.

Parameters:

expected - expected type

actual - actual type

Returns:

if supported or not
