CMapStringToString Class
Supports maps of CString objects keyed by CString objects.
class CMapStringToString : public CObject
Members
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;

Public Methods
Name |
Description |
|---|---|
Returns the number of elements in this map. |
|
Determines the current number of elements in the hash table. |
|
Gets the next element for iterating. |
|
Returns the number of elements in this map. |
|
Returns the position of the first element. |
|
Calculates the hash value of a specified key. |
|
Initializes the hash table. |
|
Tests for the empty-map condition (no elements). |
|
Looks up a void pointer based on the void pointer key. The pointer value, not the entity it points to, is used for the key comparison. |
|
Returns a reference to the key associated with the specified key value. |
|
Gets a pointer to the first CString in the map. |
|
Gets a pointer to the next CString for iterating. |
|
Returns a pointer to a CString whose value matches the specified value. |
|
Removes all the elements from this map. |
|
Removes an element specified by a key. |
|
Inserts an element into the map; replaces an existing element if a matching key is found. |
Public Operators
Name |
Description |
|---|---|
Inserts an element into the map — operator substitution for SetAt. |
Remarks
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.
