closetag()

void closetag ( std::ostream & file, const std::string & tag ) const

inlineinherited

Print out end of tag marker. Print contents if not empty else print simple close tag.

getattr() [1/5]

bool getattr ( const std::string & n, bool & v, bool erase = true )

inlineinherited

Find an attribute named n and set the bool variable v to true if the corresponding value is "yes". Remove the correspondig attribute from the list if found and erase is true.

Returns

false if no attribute was found.

getattr() [2/5]

bool getattr ( const std::string & n, double & v, bool erase = true )

inlineinherited

Find an attribute named n and set the double variable v to the corresponding value. Remove the correspondig attribute from the list if found and erase is true.

Returns

false if no attribute was found.

getattr() [3/5]

bool getattr ( const std::string & n, int & v, bool erase = true )

inlineinherited

Find an attribute named n and set the long variable v to the corresponding value. Remove the correspondig attribute from the list if found and erase is true.

Returns

false if no attribute was found.

getattr() [4/5]

bool getattr ( const std::string & n, long & v, bool erase = true )

inlineinherited
