Member Function Documentation

void lout::misc::StringBuffer::append ( const char *  str )

inline

Append a NUL-terminated string to the buffer, with copying.

A copy is kept in the buffer, so the caller does not have to care about memory management.

void lout::misc::StringBuffer::appendNoCopy

(

char *

str

)

Append a NUL-terminated string to the buffer, without copying.

No copy is made, so this method should only be used in cases, where the string would otherwise be freed again. (This method may then save some CPU cycles.)

void lout::misc::StringBuffer::clear

(

)

Remove all strings appended to the string buffer.

Referenced by ~StringBuffer().

const char * lout::misc::StringBuffer::getChars

(

)

Return a NUL-terminated strings containing all appended strings.

The caller does not have to free the string, this is done in misc::StringBuffer::~StringBuffer.
