Theoretical class Requirements

Classes whose instances will be stored in STL containers must have:

a copy constructor

operator=

If the instances will be sorted or compared then the class must have:

operator==

operator<

Practical class requirements

In practice, it may be necessary to please the compiler gods by defining some functions that are never called. The practical list of requirements is:

a default constructor

a copy constructor

operator=

operator==

operator<

With the current release of CodeWarrior, every user defined type (including pointers to predefined types) requires a special macro to be used inside an STL container:

struct ContainedObject { int a; }
__MSL_FIX_ITERATORS__(ContainedObject);
