Public Member Functions | |
NCollection_Buffer (const Handle< NCollection_BaseAllocator > &theAlloc, const Standard_Size theSize=0, Standard_Byte *theData=NULL) | |
Default constructor. When theData is NULL but theSize is not 0 than buffer of specified size will be allocated. More... | |
~NCollection_Buffer () | |
Destructor. More... | |
const Standard_Byte * | Data () const |
Standard_Byte * | ChangeData () |
bool | IsEmpty () const |
Standard_Size | Size () const |
Return buffer length in bytes. More... | |
const Handle< NCollection_BaseAllocator > & | Allocator () const |
void | SetAllocator (const Handle< NCollection_BaseAllocator > &theAlloc) |
Assign new buffer allocator with de-allocation of buffer. More... | |
bool | Allocate (const Standard_Size theSize) |
Allocate the buffer. More... | |
void | Free () |
De-allocate buffer. More... | |
![]() | |
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 void | Delete () const |
Memory deallocator for transient classes. More... | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
Returns a type descriptor about this object. More... | |
Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
Returns a true value if this is an instance of Type. More... | |
Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
Returns a true value if this is an instance of TypeName. More... | |
Standard_Boolean | IsKind (const opencascade::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... | |
Standard_Transient * | This () const |
Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. More... | |
Standard_Integer | GetRefCount () const |
Get the reference counter of this object. More... | |
void | IncrementRefCounter () const |
Increments the reference counter of this object. More... | |
Standard_Integer | DecrementRefCounter () const |
Decrements the reference counter of this object; returns the decremented value. More... | |

typedef void | base_type |
Returns a type descriptor about this object. More... | |
![]() | |
static const char * | get_type_name () |
Returns a type descriptor about this object. More... | |
static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
Returns type descriptor of Standard_Transient class. More... | |
