Member Function Documentation

kAlloc kObject_Alloc ( kObject  object)
inherited

Gets the memory allocator associated with this object.

Most objects are constructed with an allocator, which is used to allocate the memory required by the object. Objects retain a reference to this allocator to enable further allocations and to free memory when the object is destroyed.

Parameters
objectObject.
Returns
Memory allocator.
See also
kAlloc, kObject_Alloc_
kStatus kObject_Clone ( kObject object,
kObject  source,
kAlloc  allocator 
)
inherited

Constructs a new object by copying an existing object, including any aggregated child elements.

If the source object is an object collection (e.g. kArrayList<kString>), any aggregated child objects are also cloned. In this case, the kObject_Dispose method can be used to free the cloned collection and its associated elements.

This method will fail if the source object (or an aggregated child element) does not support cloning.

Parameters
objectReceives the constructed object.
sourceSource object.
allocatorMemory allocator (or kNULL for default).
Returns
Operation status.
See also
kObject_Dispose
kStatus kObject_Destroy ( kObject  object)
inherited

Destroys the object.

The kObject_Destroy method destroys the object itself and any resources that are owned by the object. See Object Destruction for more information.

When an object is destroyed (or disposed), its reference count is decremented. The object is only truly destroyed when the reference count reaches zero. See Reference Counting for more information.

Parameters
objectObject (or kNULL).
Returns
Operation status.
See also
Object Destruction, Reference Counting
kStatus kObject_Dispose ( kObject  object)
inherited

Destroys the object and any aggregated child elements.

The kObject_Dispose method destroys the object itself, any resources that are owned by the object, and if the object represents a collection of objects, any child objects in the collection. See Object Destruction for more information.

When an object is destroyed (or disposed), its reference count is decremented. The object is only truly destroyed when the reference count reaches zero. See Reference Counting for more information.

Parameters
objectObject (or kNULL).
Returns
Operation status.

Object Destruction, Reference Counting
kBool kObject_Equals ( kObject  object,
kObject  other 
)
inherited

Determines whether the object is equal to another object.

By default, objects are compared by reference; objects are considered equal if the given handles refer to the same object instance. However, some classes override the Equals method to provide a more meaningful comparison (e.g. kString).

Parameters
objectObject.
otherObject for comparison.
Returns
kTRUE if the objects are equal.
kSize kObject_HashCode ( kObject  object)
inherited

Gets a hash code representing the state of this object.

By default, objects return a hash code based on the object handle value. However, some classes override the HashCode method to provide a more useful hash (e.g. kString).

Parameters
objectObject.
Returns
Hash code.
kBool kObject_Is ( kObject  object,
kType  type 
)
inherited

Determines whether this object is an instance of the specified type.

This function compares the type of this object with the given type. An object is considered to be an instance of a given type if a) the type represents a class and this object inherits from (or instantiates) that class, or b) the type represents an interface and this object implements the interface.

Parameters
objectObject.
typeType.
Returns
kTRUE if the object is of the specified type; otherwise kFALSE.
See also
kObject_Is_, kType_Is
kBool kObject_IsShared ( kObject  object)
inherited

Reports whether the object is currently shared (reference count greater than one).

Objects are initialized with a reference count of one. The kObject_Share method can be used to increment the reference count. The kObject_Destroy and kObject_Dispose methods decrease the reference count, and when the reference count reaches zero, the object is actually destroyed/disposed.

This method can be used to determine if the reference count of an object is currently greater than one.

This method is thread-safe.

Parameters
objectObject.
Returns
kTRUE if the object is shared; kFALSE otherwise.
See also
Reference Counting, kObject_Share
kStatus kObject_SetPool ( kObject  object,
kObjectPool  pool 
)
inherited

Sets the object pool associated with this object.

Object pools can be used to implement custom lifecycle management. If an object has an assigned pool, then the kObjectPool_Reclaim method will be called just prior to destruction, to provide an opportunity for the object to be reclaimed.

Parameters
objectObject.
poolPool object (or kNULL to clear the pool assignment).
Returns
Operation status.
kStatus kObject_Share ( kObject  object)
inherited

Increments the reference count associated with this object.

This method is thread-safe.

Parameters
objectObject.
Returns
Operation status.
See also
reference-counting
kSize kObject_Size ( kObject  object)
inherited

Estimates the memory consumed by this object, including any aggregated child elements.

This method can be optionally overridden by kObject-derived classes to report the amount of memory consumed by an object. The default implementation reports only the size of the class instance (additional allocations performed by the class are excluded).

Parameters
objectObject.
Returns
Object size, in bytes.
kType kObject_Type ( kObject  object)
inherited

Returns the type of the object.

Each object is an instance of a specific class type. The type handle returned by this function can be used to learn about the class.

Parameters
objectObject.
Returns
Type.

kType, kObject_Type_
kStatus kTcpServer_Accept ( kTcpServer  server,
k64u  timeout,
kTcpClient client,
kAlloc  allocator 
)

Blocks until an incoming connection is established, or the specified timeout interval elapses.

The returned connection object can be kNULL if the connection was closed by the remote client before being accepted.

Parameters
serverA kTcpServer object in the listening state.
timeoutThe timeout interval.
clientReturns a kTcpClient object representing the newly-established connection, or kNULL.
allocatorMemory allocator (or kNULL for default).
Returns
Operation status.
kStatus kTcpServer_Construct ( kTcpServer server,
kIpVersion  ipVersion,
kAlloc  allocator 
)

Constructs a kTcpServer object.

Parameters
serverDestination for the constructed object handle.
ipVersionInternet Protocol version.
allocatorMemory allocator (or kNULL for default).
Returns
Operation status.
kStatus kTcpServer_EnableReuseAddress ( kTcpServer  server,
kBool  reuse 
)

Enables or disables reuse of a local end point within a short period of time.

The option is typically used to allow a server to rebind to a local end point while a previous socket with the same local end point is in the TIME_WAIT state. This can be useful when a server must be stopped and started within a brief interval, but there is a small risk that packets with identical source/destination information could be misdirected to the new socket.

Parameters
serverkTcpServer object.
reusekTRUE to enable reuse of IP addresses; kFALSE otherwise.
Returns
Operation status.
kStatus kTcpServer_Listen ( kTcpServer  server,
kIpAddress  address,
k32u  port,
kSize  backlog 
)

Places the server into the listening state, to monitor for incoming connection requests.

The server can be placed in the listening state only once per kTcpServer object. After the server is shut down, the kTcpServer object cannot be used to listen again on another port.

Parameters
serverkTcpServer object.
addressA local IP address to which the server should bind, or kIpAddress_Any().
portA local port number to which the server should bind, or kIP_PORT_ANY.
backlogThe maximum number of pending connection requests to enqueue.
Returns
Operation status.
kStatus kTcpServer_LocalEndPoint ( kTcpServer  server,
kIpEndPoint endPoint 
)

Returns the local end point for a listening server.

Parameters
serverkTcpServer object.
endPointLocal end point.
Returns
Operation status.
kStatus kTcpServer_SetReadBuffers ( kTcpServer  server,
kSSize  socketSize,
kSSize  clientSize 
)

Sets the size of read buffers for accepted client sockets.

Socket buffers decouple the sender and receiver, so that the sender does not need to block while waiting for the receiver to receive all bytes. Client buffers improve the efficiency of the client when performing several small read operations.

Parameters
serverkTcpServer object.
socketSizeSize of the read buffer maintained by the underlying socket (-1 to leave unchanged).
clientSizeSize of the read buffer maintained by the client object (-1 to leave unchanged).
Returns
Operation status.
kStatus kTcpServer_SetWriteBuffers ( kTcpServer  server,
kSSize  socketSize,
kSSize  clientSize 
)

Sets the size of write buffers for accepted client sockets.

Socket buffers decouple the sender and receiver, so that the sender does not need to block while waiting for the receiver to receive all bytes. Client buffers improve the efficiency of the client when performing several small write operations.

By default, the client buffer size is zero and the socket buffer size is determined by the underlying operating system.

Parameters
serverkTcpServer object.
socketSizeSize of the write buffer maintained by the underlying socket (-1 to leave unchanged).
clientSizeSize of the write buffer maintained by the client object (-1 to leave unchanged).
Returns
Operation status.
kSocket kTcpServer_Socket ( kTcpServer  server)

Returns the underlying socket object.

Parameters
serverkTcpServer object.
Returns
Underlying socket object.
