CMapStringToString Class 

Supports maps of CString objects keyed by CString objects.


class CMapStringToString : public CObject

The member functions of CMapStringToString are similar to the member functions of class CMapStringToOb. Because of this similarity, you can use the CMapStringToOb reference documentation for member function specifics. Wherever you see a CObject pointer as a return value or "output" function parameter, substitute a pointer to char. Wherever you see a CObject pointer as an "input" function parameter, substitute a pointer to char.

BOOL CMapStringToOb::Lookup( const char* <key>,
                             CObject*& <rValue> ) const;

for example, translates to

BOOL CMapStringToString::Lookup( LPCTSTR <key>,
                                 CString& <rValue> ) const;

CMapStringToString incorporates the IMPLEMENT_SERIAL macro to support serialization and dumping of its elements. Each element is serialized in turn if a map is stored to an archive, either with the overloaded insertion (<<) operator or with the Serialize member function.

If you need a dump of individual CString-CString elements, you must set the depth of the dump context to 1 or greater.

When a CMapStringToString object is deleted, or when its elements are removed, the CString objects are removed as appropriate.

For more information on CMapStringToString, see the article Collections.
