CMapStringToOb::Lookup

Syntax

BOOL Lookup( const char* key, CObject*& rValue ) const;

Parameters

key

The string key that identifies the element to be looked up.

rValue

The returned value from the looked-up element.

Remarks

Lookup uses a hashing algorithm to quickly find the map element with a key that matches exactly (CString value).

Return Value

TRUE if the element was found; otherwise FALSE.

Example

CMapStringToOb map;

CAge* pa;

map.SetAt( "Bart", new CAge( 13 ) );

map.SetAt( "Lisa", new CAge( 11 ) );

map.SetAt( "Homer", new CAge( 36 ) );

map.SetAt( "Marge", new CAge( 35 ) );

ASSERT( map.Lookup( "Lisa", pa ) ); // Is "Lisa" in the map?

ASSERT( *pa == CAge( 11 ) ); // Is she 11?
