| Standard_Size | NAllocated () const |

 Public Member Functions inherited from NCollection_IncAllocator | |
| NCollection_IncAllocator (const size_t theBlockSize=DefaultBlockSize) | |
| Constructor. More... | |
| size_t | GetMemSize () const |
| Diagnostic method, returns the total allocated size. More... | |
| ~NCollection_IncAllocator () | |
| Destructor (calls Clean() internally) More... | |
| void * | Reallocate (void *anAddress, const size_t oldSize, const size_t newSize) |
| Reallocation: it is always allowed but is only efficient with the last allocated item. More... | |
| void | Reset (const Standard_Boolean doReleaseMem=Standard_True) |
| Re-initialize the allocator so that the next Allocate call should start allocating in the very begining as though the allocator is just constructed. Warning: make sure that all previously allocated data are no more used in your code! More... | |

| Public Member Functions inherited from Standard_Transient | |
| Standard_Transient () | |
| Empty constructor. More... | |
| Standard_Transient (const Standard_Transient &) | |
| Copy constructor – does nothing. More... | |
| Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. More... | |
| virtual | ~Standard_Transient () |
| Destructor must be virtual. More... | |
| virtual const Handle_Standard_Type & | DynamicType () const |
| Returns a type information object about this object. More... | |
| Standard_Boolean | IsInstance (const Handle_Standard_Type &theType) const |

| Standard_Boolean | IsKind (const Handle_Standard_Type &theType) const |
| Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
| Standard_Boolean | IsKind (const Standard_CString theTypeName) const |
| Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
| virtual Handle_Standard_Transient | This () const |
| Returns a Handle which references this object. Must never be called to objects created in stack. More... | |

| CommonBaseAllocator This method is designed to have the only one BaseAllocator (to avoid useless copying of collections). However one can use operator new to create more BaseAllocators, but it is injurious. More... | |

Detailed Description
Subclass of Incremental Allocator. It is aware of the total allocated and released memory. Used in NIS_Interactive context as private allocator that manages all memory used by interactive objects.
Constructor & Destructor Documentation
| NIS_Allocator::NIS_Allocator | ( | const size_t | theBlockSize = 24600 | ) |
Constructor.
Member Function Documentation
|
virtual |
Allocate memory with given size. Returns NULL on failure
Reimplemented from NCollection_IncAllocator.
