CMapStringToString::PLookup
Looks up the value mapped to a given key.
const CPair* PLookup(
LPCTSTR key
) const;
CPair* PLookup(
LPCTSTR key
);
Parameters
- key
A pointer to the key for the element to be searched for.
Return Value
A pointer to the specified key.
Remarks
Call this method to search for a map element with a key that exactly matches the given key.
Example
CMapStringToString myMap;
CString myStr[4]={_T("One"), _T("Two"), _T("Three"), _T("Four")};
myMap.InitHashTable(257);
// Add 4 elements to the map.
myMap.SetAt(myStr[0], _T("Odd"));
myMap.SetAt(myStr[1], _T("Even"));
myMap.SetAt(myStr[2], _T("Odd"));
myMap.SetAt(myStr[3], _T("Even"));
// Print the element values with odd key values.
CMapStringToString::CPair *pCurVal;
for (int i = 0; i < 4 ; i += 2)
{
pCurVal = myMap.PLookup(myStr[i]);
_tprintf_s(_T("Current key value at %s: %s\n"),
pCurVal->key, pCurVal->value);
}
