Enum Client.ConnectionType
java.lang.Object
java.lang.Enum<Client.ConnectionType>
com.bea.httppubsub.Client.ConnectionType
- All Implemented Interfaces:
- Serializable, Comparable<Client.ConnectionType>
- Enclosing interface:
- Client
public static enum Client.ConnectionType
- extends Enum<Client.ConnectionType>
The connection type specifies the type of transport the client requires
for communication. Different transport types described below are
distinguished primarily by how they wrap messages for delivery over HTTP
and the sequence and content of the HTTP connections initiated by clients.
-
long-polling messages are sent to the server as the message
parameter of an application/x-www-form-urlencoded encoded POST request.
Messages are sent to the client as unencapsulated body content of a POST
response.
-
callback-polling messages are sent to the server as the message
parameter of an url encoded GET request. Responses are sent wrapped in a
JavaScript callback in order to facilitate delivery. As specified by the
JSON-P pseudo-protocol, the name of the callback to be triggered is passed
to the server via the "callback" GET parameter.
-
iframe OPTIONAL transport using the document content of a hidden
iframe element.
-
flash OPTIONAL transport using the capabilities of a flush browser
plugin.

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