## Member Function Documentation

static LogString decode | ( | const char * | v | ) | `[static]`

| Returns a LogString given a string literal in the ASCII charset. Used to implement the LOG4CXX_STR macro for EBCDIC and UNICHAR.

static logchar decode | ( | char | v | ) | `[static]`

| Returns a logchar value given a character literal in the ASCII charset. Used to implement the LOG4CXX_STR macro for EBCDIC and UNICHAR.

static void decode | ( | const CFStringRef & | src,
