Description
The CStringArray class supports arrays of CString objects.
The member functions of CStringArray are similar to the member functions
of class ◄CObArray►. Because of this similarity, you can use the
CObArray reference documentation for member function specifics. Wherever
you see a CObject pointer as a return value, substitute a CString.
Wherever you see a CObject pointer as a function parameter, substitute a
const pointer to char.
CObject* CObArray::GetAt( int <nIndex> ) const;
for example, translates to
CString CStringArray::GetAt( int <nIndex> ) const;
and
void SetAt( int <nIndex>, CObject* <newElement> )
translates to
void SetAt( int <nIndex>, const char* <newElement> )
CStringArray incorporates the IMPLEMENT_SERIAL macro to support
serialization and dumping of its elements. If an array of CStrings is
stored to an archive, either with the overloaded insertion operator or
with the Serialize member function, each element is, in turn,
serialized.
If you need a dump of individual string elements in the array, you must
set the depth of the dump context to 1 or greater.
When a CString array is deleted, or when its elements are removed,
string memory is freed as appropriate.

Public Members
Construction/Destruction
◄CStringArray► Constructs an empty array for CString objects.
◄~CStringArray► Destroys a CStringArray object.
Bounds
◄GetSize► Gets number of elements in this array.
◄GetUpperBound► Returns the largest valid index.
◄SetSize► Sets the number of elements to be contained in this
array.
Operations
◄FreeExtra► Frees all unused memory above the current upper bound.
◄RemoveAll► Removes all the elements from this array.
Element Access
◄GetAt► Returns the value at a given index.
◄SetAt► Sets the value for a given index; array not allowed to
grow.
◄ElementAt► Returns a temporary reference to the element pointer
within the array.
Growing the Array
◄SetAtGrow► Sets the value for a given index, growing the array if
necessary.
◄Add► Adds an element to the end of the array; grows the array
if necessary.
Insertion/Removal
◄InsertAt► Inserts an element (or all the elements in another array)
at a specified index.
◄RemoveAt► Removes an element at a specific index.
Operators
◄operator []► Sets or gets the element at the specified index.
