| NXEncoding |
| Adopted By: | a private class | |
| Declared In: | remote/transport.h |
| Protocol Description |
| An object that implements the NXEncoding protocol is passed as the portal argument for the encodeUsing: message to distribute an object that adopts the NXTransport protocol. The object implementing the encodeUsing: method should send the portal object messages from the NXEncoding protocol to encode the data required to instantiate a copy of the object on the other end of the connection.
Every method in the NXEncoding protocol has a corresponding method in the NXDecoding protocol that will be used to receive encoded data. See the Distributed Objects introduction for more information. |
| Instance Methods |
| encodeBytes:count: |
| encodeBytes:(const void *)buffer count:(int)count |
| Encodes the buffer (of size count bytes) indicated by buffer. |
| encodeData:ofType: |
| encodeData:(void *)data ofType:(const char *)type |
| Encodes the data structure pointed to by data, whose fields are indicated by the character string type, consisting of the following values: |
| Format Character | Data Type | |
| c | char | |
| s | short | |
| i | int | |
| f | float | |
| d | double | |
| @ | id | |
| * | char * | |
| % | NXAtom | |
| : | SEL | |
| ! | int; corresponding data won't be read or written | |
| {<type>} | struct | |
| [<count><type>] | array |
| encodeMachPort: |
| encodeMachPort:(port_t)port |
| Encodes the Mach port port. |
| encodeObject: |
| encodeObject:anObject |
| Usually encodes a proxy to anObject. The object to be encoded is determined by sending anObject an encodeRemotelyFor:freeAfterEncoding:isBycopy: message, which will, by default, return a proxy to anObject. |
| encodeObjectBycopy: |
| encodeObjectBycopy:anObject |
| Usually encodes anObject, so that a copy will be instantiated on the other end of the connection; the object to be encoded is determined by sending anObject an encodeRemotelyFor:freeAfterEncoding:isBycopy: message. anObject must conform to the NXTransport protocol. |
| encodeVM:count: |
| encodeVM:(const void *)bytes count:(int)count |
| Encodes memory (of count bytes) that was allocated with vm_allocate(). |
