Enum Constant Detail

TEXT

public static final MessageType TEXT

A TextMessage to be deserialized to a String.

MAP

public static final MessageType MAP

A MapMessage to be deserialized to a Map.

BYTES

public static final MessageType BYTES

A BytesMessage to be deserialized to a byte array.

STREAM

public static final MessageType STREAM

A StreamMessage. JMS 2.0 only. Cannot deserialize, must be done by the client.

Method Detail

values

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

Returns:

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

valueOf

public static MessageType 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

fromMessage

@NonNull
public static MessageType fromMessage(@Nullable
                                               javax.jms.Message message)

Determine the MessageType corresponding to the given message. Returns UNKNOWN if the message is null or the type is not supported.

Parameters:

message - the Message whose type you would like to infer.

Returns:

the MessageType

fromObject

public static MessageType fromObject(java.lang.Object message)

Determine the MessageType corresponding to the given message. Returns UNKNOWN if the message is null or OBJECT otherwise.

Parameters:

message - the Message whose type you would like to infer.

Returns:

the MessageType
