1) Reduce the number of calls to malloc by grouping requests to larger blocks. To achieve this goal, the following ways are used:
- Containers of types sequence, list and map are initialized with an instance of NCollection_IncAllocator, at this taking care of the time of life of allocated objects, so that not to occupy huge amount of memory.
- Allocation of several arrays having the same and short life time is changed so that to allocate a buffer array of necessary size and to place arrays in this buffer.
2) In BRepMesh_FastDiscretFace, optimize the function filterParameters so that to avoid excess memory allocations.
3) In NCollection_CellFilter, change declaration of the method Reset to accept array by reference rather than by value.
4) Add Allocator() method in map, sequence and vector collection classes by analogy with list collection.
5) Correct the size of block for IncAllocator for x64 platform. In order free-ed block to be returned to the system its size should be at least 1024K on x64 and 512K on x86. This allows to retain free virtual space almost to the state before algorithm run.
6) Decrease amount of memory zeroed by calloc. For that, reduce theIncrement parameter of the embedded vectors of the classes NCollection_UBTreeFiller and BRepMesh_VertexInspector to default value 256.
7) Avoid computing bounding box when not necessary (if no relative deflection is used)
8) Cycles by wires of face using TopExp_Explorer are converted to use TopoDS_Iterator instead.
9) BRepMesh_FastDiscret::Add optimized to avoid storing sequences of faces and edges
10) The tests "mesh standard_* W7" are corrected to accept the new behavior. Earlier the following error took place:
Not connected mesh inside face 9
{12 13}
Now this error was replaced with another one:
free nodes (in pairs: face / node):
{9 12}
Actually it is not a regression, rather improvement, if we look at the snapshot.
11) Change other test cases to their actual state.
Destructors of collection classes from NCollection and math_Function are made virtual to allow safe destruction by pointer to base class.
Destructors of classes HatchGen_IntersectionPoint, IntCurveSurface_Intersection, Intf_Interference, IntRes2d_Intersection are made protected to avoid possibility of destructing by pointer to corresponding base class.
New features:
1. class NCollection_BaseVector
method:
void SetIncrement(const Standard_Integer aIncrement)
has been added.
The method allows to set the size of increment dynamically
[ not in constructor ].
2 class BOPCol_Array1
has been removed.

have been modified to take into account New features: 1 and 2
2. class BOPTest_Chronometer
has been modified to use the driver of the type
OSD_Timer instead OSD_Chronometer
NCollection classes amended to be compatible with TCollection equivalents:
- List and Maps: copy constructor is used for placement of new items in collection instead of assignment operator, thus default constructor is not necessary any more for the item class
- Constructors with additional argument of element type added in array classes operated by Handle, defined by NCollection_DefineHArray*.hxx, allowing to initialize array immediately by specified value
- Non-const methods First() and Last() are added in List class, and method Value() in TListIterator class
- Method Append() accepting Handle(HSequence) provided in NCollection_DefineHSequence.hxx
- Default implementation of global function IsEqual() is provided as template (using operator ==)
Code using lists and maps of sequences is refactored to operate sequence by Handle (since Sequence does not to have public copy constructor).
In addition, error checking code is simplified to use macros _Raise_if instead of custom #ifdefs with the same meaning.
Comments within declaration of instances of generic classes in CDL removed.
Fixed bug in copy constructor of NCollection_BaseVector leading to corrupt data if original vector is empty; simplistic test command for vectors is added.
NCollection_BaseCollection class, relevant header files, and macro DEFINE_BASECOLLECTION removed.
Hence methods Assign() from other compatible (via inheritance of BaseCollection) collections are not available any more, as well as base Iterator class.
All methods of Iterator classes are made non-virtual, allowing their inline expansion for better performance.
OCCT-specific operators new and delete added to collection classes and removed from iterator classes.
STL-compatible iterators returned methods begin() and end() are provided in collection classes from NCollection package.
NCollection_Array1::Iterator is redesigned to use pointer instead of index.
Iterators of Sequence, Array, and Vector are extended by new methods to iterate backwards.
Use of SortTools_QuickSortOfReal is replaced by std::sort() in a few places (where possible).
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
