bool SWBasicFilter::handleEscapeString ( SWBuf &  buf, const char *  escString, BasicFilterUserData *  userData  )

protectedvirtualinherited

This function is called for every escape sequence encountered in the input text.

Parameters

buf	the output buffer
escString	the escape sequence (e.g. "amp" for &)
userData	user storage space for data transient to 1 full buffer parse

Returns

false if was not handled and should be handled in

subclasses should return true if they handled the esc seq, or false if they did not.

Definition at line 286 of file swbasicfilter.cpp.

                                                                                                       {

bool SWBasicFilter::handleNumericEscapeString ( SWBuf &  buf, const char *  escString  )

protectedvirtualinherited

This function is called for all numeric escape sequences. If passThrough

Parameters

buf	the output buffer
escString	the escape sequence (e.g. "#235" for &235;)

Returns

subclasses should return true if they handled the esc seq, or false if they did not.

Definition at line 244 of file swbasicfilter.cpp.

                                                                               {

    return false;
}

bool ThMLCGI::handleToken ( SWBuf &  buf, const char *  token, BasicFilterUserData *  userData  )

protectedvirtual

This function is called for every token encountered in the input text.

Parameters

buf	the output buffer
token	the token (e.g. "p align='left'"
userData	user storage space for data transient to 1 full buffer parse

Returns

subclasses should return true if they handled the token, or false if they did not.
