| kStatus kHttpServerResponse_AddHeader | ( | kHttpServerResponse | response, |
| const kChar * | name, | ||
| const kChar * | value | ||
| ) |
Adds a header value to the response.
Headers that can be determined from the information provided in other functions (e.g. 'Content-Length', 'Transfer-Encoding', 'Connection') will be generated automatically and should not normally be provided via this function.
If multiple headers with the same field name are provided, each subsequent header value will be added to the previous header values (comma-separated).
Leading headers should be added prior to writing the message body. Trailing headers can be generated by calling this function after writing at least one chunk-encoded body segment.
| response | Response object. |
| name | Header field name. |
| value | Header field value. |
| kStatus kHttpServerResponse_BeginWriteChunk | ( | kHttpServerResponse | response, |
| k64u | length, | ||
| kStream * | stream | ||
| ) |
Begins writing a chunk-encoded message body segment.
Use the stream provided by this function to write the message chunk. Call this function with a length of zero to signify that writing is complete.
Use of this function will automatically add the 'Transfer-Encoding: chunked' header.
| response | Response object. |
| length | Length of the message chunk, in bytes. |
| stream | Receives a reference to a stream object that should be used to write the message chunk. |
| kStatus kHttpServerResponse_BeginWriteContent | ( | kHttpServerResponse | response, |
| k64u | length, | ||
| kStream * | stream | ||
| ) |
Begins writing a simple message body.
Use the stream provided by this function to write the message body.
Use of this function will automatically add the 'Content-Length' header.
| response | Response object. |
| length | Total length of the message body, in bytes. |
| stream | Receives a reference to a stream object that should be used to write the message body. |
| kStatus kHttpServerResponse_SetClosed | ( | kHttpServerResponse | response, |
| kBool | closed | ||
| ) |
Instructs the HTTP server to close this connection when message processing is complete.
This function can only be called prior to writing the message body.
Use of this function will automatically add the 'connection: closed' header.
| response | Response object. |
| closed | kTRUE to close the connection; kFALSE otherwise. |
| kStatus kHttpServerResponse_SetHeader | ( | kHttpServerResponse | response, |
| const kChar * | name, | ||
| const kChar * | value | ||
| ) |
Sets the value of a header in the response.
Headers that can be determined from the information provided in other functions (e.g. 'Content-Length', 'Transfer-Encoding', 'Connection') will be generated automatically and should not normally be provided via this function.
Leading headers should be added prior to writing the message body. Trailing headers can be generated by calling this function after writing at least one chunk-encoded body segment.
| response | Response object. |
| name | Header field name. |
| value | Header field value. |
| kStatus kHttpServerResponse_SetReason | ( | kHttpServerResponse | response, |
| const kChar * | reason | ||
| ) |
Sets the HTTP status description associated with this response.
If a custom description is not provided, a default description based on the status code will be sent.
This function can only be called prior to writing the message body.
| response | Response object. |
| reason | HTTP status description. |
| kStatus kHttpServerResponse_SetStatus | ( | kHttpServerResponse | response, |
| kHttpStatus | status | ||
| ) |
Sets the HTTP status code associated with this response.
By default, status code 200 (OK) is assumed.
This function can only be called prior to writing the message body.
| response | Response object. |
| status | HTTP status code. |
| kStatus kHttpServerResponse_SetVersion | ( | kHttpServerResponse | response, |
| kVersion | version | ||
| ) |
Sets the version associated with this HTTP response.
By default, version 1.1 is assumed.
This function can only be called prior to writing the message body.
| response | Response object. |
| version | Message version. |
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.
| object | Object. |
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.
| object | Receives the constructed object. |
| source | Source object. |
| allocator | Memory allocator (or kNULL for default). |
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.
| object | Object (or kNULL). |
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.
| object | Object (or kNULL). |
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).
| object | Object. |
| other | Object for comparison. |
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).
| object | Object. |
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.
| object | Object. |
| type | Type. |
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.
| object | Object. |

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.
| object | Object. |
| pool | Pool object (or kNULL to clear the pool assignment). |
Increments the reference count associated with this object.
This method is thread-safe.
| object | Object. |
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).
| object | Object. |
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.
| object | Object. |
