Implicitly shared classes are + both safe and efficient when passed as arguments, because only a + pointer to the data is passed around, and the data is copied only + if and when a function writes to it, i.e., \e {copy-on-write}. + + \tableofcontents + + \section1 Overview + + A shared class consists of a pointer to a shared data block that + contains a reference count and the data. + + When a shared object is created, it sets the reference count to 1. The + reference count is incremented whenever a new object references the + shared data, and decremented when the object dereferences the shared + data. The shared data is deleted when the reference count becomes + zero. + + \keyword deep copy + \keyword shallow copy + + When dealing with shared objects, there are two ways of copying an + object. We usually speak about \e deep and \e shallow copies. A deep + copy implies duplicating an object. A shallow copy is a reference + copy, i.e. just a pointer to a shared data block. Making a deep copy + can be expensive in terms of memory and CPU. Making a shallow copy is + very fast, because it only involves setting a pointer and incrementing + the reference count. + + Object assignment (with operator=()) for implicitly shared objects is + implemented using shallow copies. + + The benefit of sharing is that a program does not need to duplicate + data unnecessarily, which results in lower memory use and less copying + of data. Objects can easily be assigned, sent as function arguments, + and returned from functions. + + Implicit sharing takes place behind the scenes; the programmer + does not need to worry about it. Even in multithreaded + applications, implicit sharing takes place, as explained in + \l{Thread-Support in Qt Modules#Threads and Implicitly Shared Classes} + {Threads and Implicitly Shared Classes}. + + When implementing your own implicitly shared classes, use the + QSharedData and QSharedDataPointer classes. + + \section1 Implicit Sharing in Detail + + Implicit sharing automatically detaches the object from a shared + block if the object is about to change and the reference count is + greater than one. (This is often called \e {copy-on-write} or + \e {value semantics}.) + + An implicitly shared class has total control of its internal data. In + any member functions that modify its data, it automatically detaches + before modifying the data. + + The QPen class, which uses implicit sharing, detaches from the shared + data in all member functions that change the internal data. + + Code fragment: + \snippet doc/src/snippets/code/doc_src_groups.cpp 0 + + + \section1 List of Classes + + The classes listed below automatically detach from common data if + an object is about to be changed. The programmer will not even + notice that the objects are shared. Thus you should treat + separate instances of them as separate objects. They will always + behave as separate objects but with the added benefit of sharing + data whenever possible. For this reason, you can pass instances + of these classes as arguments to functions by value without + concern for the copying overhead. + + Example: + \snippet doc/src/snippets/code/doc_src_groups.cpp 1 + + In this example, \c p1 and \c p2 share data until QPainter::begin() + is called for \c p2, because painting a pixmap will modify it. + + \warning Do not
