Summary0008503: FIP 8.17 : Hide the objects to deny unauthorized operations with memory manager
DescriptionThe current Open CASCADE memory manager contains static functions and global
variables that are just for internal usage by memory manager itself. These
objects are accessible for the end user, provoking to use them. The aim of this
work is to provide object-oriented software architecture that will be able to
deny unauthorized operations with the memory manager.
Additional information
and documentation updates		Documentation remark, added by PKV 2005-03-29 09:48:51:

New features:
1.The following set of static functions is considered as general interface
between the user and the memory manager [1]:

* Standard_Address Standard::Allocate (const Standard_Integer aSize);
* Standard_Address Standard::Reallocate (Standard_Address& anAddr, const
Standard_Integer aNewSize);
* void Standard::Free (Standard_Address& anAddr);
* void Standard::Purge ( );
2.The abstract class Standard_MMgrRoot contains the following interface of the
memory manager object:
public:
 Standard_Address Allocate (const Standard_Integer aSize) =0;
 Standard_Address Reallocate (Standard_Address& anAddr, const Standard_Integer
aNewSize) =0;
 void Free (Standard_Address& anAddr) =0;
 void Purge ( )=0;
 ~ Standard_MMgrRoot ( )=0; // destructor
protected:
 void Initialize ( ) =0; // initializes the fields of the object

These methods are pure virtual functions of the abstract class
Standard_MMgrRoot. The classes that inherit from Standard_MMgrRoot contain the
concrete implementation of the methods above.
3.Implementation:
3.1 Standard_MMgrOpt – the class containing implementation of the current memory
manager for the operating parameter MMGT_OPT=1 [1] (so called optimal memory
manager);
3.2 Standard_MMgrRaw - the class containing implementation of the current memory
manager for the operating parameter MMGT_OPT=0 [1] (so called non-optimal memory
manager);
Modified entities:
The following modifications of the sources of the Open CASCADE have been done:
* Methods removed from the class Standard:
- void Standard::StorageManagerInit ( )
- Standard_Address Standard::MAllocate (const Standard_Integer )
- void Standard::MFree (Standard_Address& )
- void Standard::Free (Standard_Address& , const Standard_Integer )
- Standard_Address Standard::Reallocate (Standard_Address& ,
const Standard_Integer ,
const Standard_Integer )
- Standard_Address Standard::MReallocate (Standard_Address& ,
const Standard_Integer )
- Standard_Address Standard::RReallocate (Standard_Address& ,
const Standard_Integer ,
const Standard_Integer )
- Standard_Integer Standard::AllocatedLength (const Standard_Address )
- Standard_Boolean Standard::ReAllocatedLength (const Standard_Address ,
const Standard_Integer )
- void Standard::StorageManagerDump (Standard_OStream& )
- Standard_Boolean Standard::Display (Standard_Ostream& ,
const Standard_CString )
- Standard_Boolean Standard::Display (const Standard_CString )


* Removed classes: StandardCSFDB, Mgt_StorageManager
* Removed files: Standard_Allocate.lxx , StandardCSFDB.cxx
Mgt_StorageManager.cdl/cxx/lxx
* Files modified due to disappearance the methods of the class Standard.
