A StreamMessage object is used to send a stream of primitive types in the .NET programming language. It is filled and read sequentially. It inherits from the Message interface and adds a stream message body. The primitive types can be read or written explicitly using methods for each type. They may also be read or written generically as objects. For instance, a call to IStreamMessage.WriteInt32(6) is equivalent to StreamMessage.WriteObject( (Int32)6 ). Both forms are provided, because the explicit form is convenient for static programming, and the object form is needed when types are not known at compile time. When the message is first created, and when ClearBody is called, the body of the message is in write-only mode. After the first call to reset has been made, the message body is in read-only mode. After a message has been sent, the client that sent it can retain and modify it without affecting the message that has been sent. The same message object can be sent multiple times. When a message has been received, the provider has called reset so that the message body is in read-only mode for the client. If ClearBody is called on a message in read-only mode, the message body is cleared and the message body is in write-only mode. If a client attempts to read a message in write-only mode, a MessageNotReadableException is thrown. If a client attempts to write a message in read-only mode, a MessageNotWriteableException is thrown. IStreamMessage objects support the following conversion table. The marked cases must be supported. The unmarked cases must throw a NMSException. The String-to-primitive conversions may throw a runtime exception if the primitive's valueOf() method does not accept it as a valid String representation of the primitive. A value written as the row type can be read as the column type. | | boolean byte short char int long float double String byte[] |---------------------------------------------------------------------- |boolean | X X |byte | X X X X X |short | X X X X |char | X X |int | X X X |long | X X |float | X X X |double | X X |String | X X X X X X X X |byte[] | X |----------------------------------------------------------------------
