Detailed Description

A class representing a single row or element of a table in a DBStore.

This class holds the data of a row in a table.

Definition at line 219 of file common.h.

Constructor & Destructor Documentation

DataElem::DataElem (  DBStore *  c  ) 
 

Constructs a DataElem. This function needs a container because the size, types of keys and primary key are all defined by the containing database

Definition at line 1046 of file common.cpp.

References contained, DBStore::getNumFields(), QPtrCollection::setAutoDelete(), size, TRUE, and values.

DataElem::~DataElem (   ) 
 

Destroys a DataElem and frees memory used by the DataElem

Definition at line 1057 of file common.cpp.

Member Function Documentation

bool DataElem::closer (  DataElem *  d1,
DataElem *  d2,
TVVariant  target,
int  column
)  [static]
 

Determins which of the first to parameters are closer to the third, target parameter.

Returns:
  • TRUE if the first element is a closer match to the target than the second element
  • FALSE if the first element is not a closer match to the target than the second element
