This is an even more efficient alternative to StringCompressor in that it writes a single byte from a lookup table and only does compression if the string does not already exist in the table. All string tables must match on all systems - hence you must add all the strings in the same order on all systems. Furthermore, this must be done before sending packets that use this class, since the strings are ordered for fast lookup. Adding after that time would mess up all the indices so don't do it. Don't use this class to write strings which were not previously registered with AddString, since you just waste bandwidth then. Use StringCompressor instead.
StringTable * StringTable::Instance | ( | void | ) | [static] |
static function because only static functions can access static members The RakPeer constructor adds a reference to this class, so don't call this until an instance of RakPeer exists, or unless you call AddReference yourself.
void StringTable::AddString | ( | const char * | str, | |
bool | copyString | |||
) |
Add a string to the string table.
[in] | str | The string to add to the string table |
[in] | copyString | true to make a copy of the passed string (takes more memory), false to not do so (if your string is in static memory). |
void StringTable::EncodeString | ( | const char * | input, | |
int | maxCharsToWrite, | |||
RakNet::BitStream * | output | |||
) |
Writes input to output, compressed. Takes care of the null terminator for you. Relies on the StringCompressor class, which is automatically reference counted in the constructor and destructor in RakPeer. You can call the reference counting functions yourself if you wish too.
[in] | input | Pointer to an ASCII string |
[in] | maxCharsToWrite | The size of input |
[out] | output | The bitstream to write the compressed string to |
bool StringTable::DecodeString | ( | char * | output, | |
int | maxCharsToWrite, | |||
RakNet::BitStream * | input | |||
) |
Writes input to output, uncompressed. Takes care of the null terminator for you. Relies on the StringCompressor class, which is automatically reference counted in the constructor and destructor in RakPeer. You can call the reference counting functions yourself if you wish too.
[out] | output | A block of bytes to receive the output |
[in] | maxCharsToWrite | Size, in bytes, of output . A NULL terminator will always be appended to the output string. If the maxCharsToWrite is not large enough, the string will be truncated. |
[in] | input | The bitstream containing the compressed string |
void StringTable::LogStringNotFound | ( | const char * | strName | ) | [protected] |
Called when you mess up and send a string using this class that was not registered with AddString
[in] | maxCharsToWrite | Size, in bytes, of output . A NULL terminator will always be appended to the output string. If the maxCharsToWrite is not large enough, the string will be truncated. |
