Call this method to look up keys or values in the CAtlMap object.
Syntax
bool Lookup(
KINARGTYPE key,
VOUTARGTYPE value
) const;
const CPair* Lookup(
KINARGTYPE key
) const throw( );
CPair* Lookup(
KINARGTYPE key
) throw( );
Parameters
key
Specifies the key that identifies the element to be looked up.value
Variable that receives the looked-up value.
Return Value
The first form of the method returns true if the key is found, otherwise false. The second and third forms return a pointer to a CPair which can be used as a position for calls to CAtlMap::GetNext and so on.
Remarks
Lookup uses a hashing algorithm to quickly find the map element containing a key that exactly matches the given key parameter.
