Known Direct Subclasses |
RtpStream represents the base class of streams which send and receive network packets with media payloads over Real-time Transport Protocol (RTP).
Using this class requires
INTERNET
permission.

This mode indicates that the stream sends and receives packets at the same time. |
int |
MODE_RECEIVE_ONLY
This mode indicates that the stream only receives packets. |
int |
MODE_SEND_ONLY
This mode indicates that the stream only sends packets. |

int MODE_NORMAL
This mode indicates that the stream sends and receives packets at the same time. This is the initial mode for new streams.
Constant Value: 0 (0x00000000)
int MODE_RECEIVE_ONLY
This mode indicates that the stream only receives packets.
Constant Value: 2 (0x00000002)
int MODE_SEND_ONLY
This mode indicates that the stream only sends packets.
Constant Value: 1 (0x00000001)
void associate (InetAddress address, int port)
Associates with a remote host. This defines the destination of the outgoing packets.
Parameters | |
---|---|
address |
InetAddress :
The network address of the remote host. |
port |
int :
The network port of the remote host. |
Throws | |
---|---|
IllegalArgumentException |
if the address is not supported or the port is invalid. |
IllegalStateException |
if the stream is busy. |

boolean isBusy ()
Returns true
if the stream is busy. In this case most of the
setter methods are disabled. This method is intended to be overridden
by subclasses.
Returns | |

boolean |
void release ()
Releases allocated resources. The stream becomes inoperable after calling this method.
Throws | |
---|---|
IllegalStateException |
if the stream is busy. |

void setMode (int mode)
Changes the current mode. It must be one of MODE_NORMAL
,
MODE_SEND_ONLY
, and MODE_RECEIVE_ONLY
.
Parameters | |
---|---|
mode |
int :
The mode to change to. |
Throws | |
---|---|
IllegalArgumentException |
if the mode is invalid. |
IllegalStateException |
if the stream is busy. |

void finalize ()
Called by the garbage collector on an object when garbage collection
determines that there are no more references to the object.
A subclass overrides the finalize
method to dispose of
system resources or to perform other cleanup.
The general contract of finalize
is that it is invoked
if and when the JavaTM virtual
machine has determined that there is no longer any
means by which this object can be accessed by any thread that has
not yet died, except as a result of an action taken by the
finalization of some other object or class which is ready to be
finalized. The finalize
method may take any action, including
making this object available again to other threads; the usual purpose
of finalize
, however, is to perform cleanup actions before
the object is irrevocably discarded. For example, the finalize method
for an object that represents an input/output connection might perform
explicit I/O transactions to break the connection before the object is
permanently discarded.
The finalize
method of class Object
performs no
special action; it simply returns normally. Subclasses of
Object
may override this definition.
The Java programming language does not guarantee which thread will
invoke the finalize
method for any given object. It is
guaranteed, however, that the thread that invokes finalize will not
be holding any user-visible synchronization locks when finalize is
invoked. If an uncaught exception is thrown by the finalize method,
the exception is ignored and finalization of that object terminates.
After the finalize
method has been invoked for an object, no
further action is taken until the Java virtual machine has again
determined that there is no longer any means by which this object can
be accessed by any thread that has not yet died, including possible
actions by other objects or classes which are ready to be finalized,
at which point the object may be discarded.
The finalize
method is never invoked more than once by a Java
virtual machine for any given object.
Any exception thrown by the finalize
method causes
the finalization of this object to be halted, but is otherwise
ignored.
