CMap::PLookup
Finds the value mapped to a given key.
const CPair* PLookup(
ARG_KEY key
) const;
CPair* PLookup(
ARG_KEY key
);
Parameters
- key
Key for the element to be searched for.
Return Value
A pointer to a key structure; see CMap::CPair.
Remarks
Call this method to search for a map element with a key that exactly matches the given key.
Example
typedef CMap<int, int, CPoint, CPoint> CMyMap;
CMyMap myMap;
myMap.InitHashTable(257);
// Add 10 elements to the map.
for (int i = 0; i <= 10; i++)
myMap[i] = CPoint(i, i);
// Print the element values with even key values.
CMyMap::CPair *pCurVal;
for (int i = 0; i <= myMap.GetCount() ; i += 2)
{
pCurVal = myMap.PLookup(i);
_tprintf_s(_T("Current key value at %d: %d,%d\n"),
pCurVal->key, pCurVal->value.x, pCurVal->value.y);
}
