DESCRIPTION
The QStrList class provides a doubly-linked list of char*.
If you want a string list of QStrings use QStringList.
This class is a QPtrList<char> instance (a list of char*).
QStrList can make deep or shallow copies of the strings that are
inserted.
A deep copy means that memory is allocated for the string and then the
string data is copied into that memory. A shallow copy is just a copy
of the pointer value and not of the string data itself.
The disadvantage of shallow copies is that because a pointer can be
deleted only once, the program must put all strings in a central place
and know when it is safe to delete them (i.e. when the strings are no
longer referenced by other parts of the program). This can make the
program more complex. The advantage of shallow copies is that they
consume far less memory than deep copies. It is also much faster to
copy a pointer (typically 4 or 8 bytes) than to copy string data.
A QStrList that operates on deep copies will, by default, turn on auto-
deletion (see setAutoDelete()). Thus, by default QStrList will
deallocate any string copies it allocates.
The virtual compareItems() function is reimplemented and does a case-
sensitive string comparison. The inSort() function will insert strings
in sorted order. In general it is fastest to insert the strings as they
come and sort() at the end; inSort() is useful when you just have to
add a few extra strings to an already sorted list.
The QStrListIterator class is an iterator for QStrList.
See also Collection Classes, Text Related Classes, and Non-GUI Classes.
MEMBER FUNCTION DOCUMENTATIONQStrList::QStrList ( bool deepCopies = TRUE )
Constructs an empty list of strings. Will make deep copies of all
inserted strings if deepCopies is TRUE, or use shallow copies if
deepCopies is FALSE.
QStrList::QStrList ( const QStrList & list )
Constructs a copy of list.
If list has deep copies, this list will also get deep copies. Only the
pointers are copied (shallow copy) if the other list does not use deep
copies.
QStrList::~QStrList ()
Destroys the list. All strings are removed.
QStrList & QStrList::operator= ( const QStrList & list )
Assigns list to this list and returns a reference to this list.
If list has deep copies, this list will also get deep copies. Only the
pointers are copied (shallow copy) if the other list does not use deep
copies.
