string FieldExt::as_string (   )  const

Returns a string representation of a field.

char * FieldExt::evaluate (  char *  tuple1, char *  tuple2 )  [virtual]

Implements OFunction.

char * FieldExt::evaluate (  char *  tuple  )  [virtual]

Implements OFunction.

char * FieldExt::evaluateAsChar (  char *  tuple, int32 &  return_size, bool  addnull )  [virtual]

char * FieldExt::evaluateAsChar (  char *  tuple, int32 &  return_size )  [virtual]

void FieldExt::evaluateIntoLocation (  char *  tuple, char *  loc )
