Set limit on given unit.

All objects together don't have to exceed that limit.

Reimplemented from HxDefaultDataObjectManager. 

00121 {
00122     if(unit == ROWS_UNIT) _totalRowLimit = value;
00123     else if(unit == COLS_UNIT) _totalColLimit = value;
00124     HxDefaultDataObjectManager::setTotalLimit(unit, value);
00125 }

int HxImageRepManager::getTotalLimit (  HxString    unit )  [virtual]
 

Reimplemented from HxDefaultDataObjectManager. 

00129 {

00133 }

void HxImageRepManager::setObjectLimit (  HxString    unit,
int    value
)  [virtual]
 

Set limit (per object) on given unit.

Any object can exceed that limit.

00115     else if(unit == COLS_UNIT) return _imageColLimit;
00116     else return HxDefaultDataObjectManager::getObjectLimit(unit);
00117 }

int HxImageRepManager::getUsed (  HxString    unit )  [virtual]
 

Reimplemented from HxDefaultDataObjectManager.
