CStringList Class

Supports lists of CString objects.

class CStringList : public CObject

Members

The member functions of CStringList are similar to the member functions of class CObList. Because of this similarity, you can use the CObList reference documentation for member function specifics. Wherever you see a CObject pointer as a return value, substitute a CString (not a CString pointer). Wherever you see a CObject pointer as a function parameter, substitute an LPCTSTR.

CObject*& CObList::GetHead() const;

for example, translates to

CString& CStringList::GetHead() const;

and

POSITION AddHead( CObject* <newElement> );

translates to

POSITION AddHead( LPCTSTR <newElement> );

Description

CObList::AddHead

Adds an element (or all the elements in another list) to the head of the list (makes a new head).

CObList::AddTail

Adds an element (or all the elements in another list) to the tail of the list (makes a new tail).

CObList::Find

Gets the position of an element specified by pointer value.

CObList::FindIndex

Gets the position of an element specified by a zero-based index.

CObList::GetAt

Gets the element at a given position.

CObList::GetCount

Returns the number of elements in this list.

CObList::GetHead

Returns the head element of the list (cannot be empty).

CObList::GetHeadPosition

Returns the position of the head element of the list.

CObList::GetNext

Gets the next element for iterating.

CObList::GetPrev

Gets the previous element for iterating.

CObList::GetSize

Returns the number of elements in this list.

CObList::GetTail

Returns the tail element of the list (cannot be empty).

CObList::GetTailPosition

Returns the position of the tail element of the list.

CObList::InsertAfter

Inserts a new element after a given position.

CObList::InsertBefore

Inserts a new element before a given position.

CObList::IsEmpty

Tests for the empty list condition (no elements).

CObList::RemoveAll

Removes all the elements from this list.

CObList::RemoveAt

Removes an element from this list, specified by position.

CObList::RemoveHead

Removes the element from the head of the list.

CObList::RemoveTail

Removes the element from the tail of the list.

CObList::SetAt

Sets the element at a given position.

Remarks

All comparisons are done by value, meaning that the characters in the string are compared instead of the addresses of the strings.

CStringList incorporates the IMPLEMENT_SERIAL macro to support serialization and dumping of its elements. If a list of CString objects is stored to an archive, either with an overloaded insertion operator or with the Serialize member function, each CString element is serialized in turn.

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