Detailed Description

The package Standard provides global memory allocator and other basic services used by other OCCT components.

Member Function Documentation

Allocate()

static Standard_Address Standard::Allocate ( const Standard_Size  aSize )

static

Allocates memory blocks aSize - bytes to allocate.

AllocateAligned()

static Standard_Address Standard::AllocateAligned ( const Standard_Size  theSize, const Standard_Size  theAlign  )

static

Allocates aligned memory blocks. Should be used with CPU instructions which require specific alignment. For example: SSE requires 16 bytes, AVX requires 32 bytes.

Parameters

theSize	bytes to allocate
theAlign	alignment in bytes

Free() [1/2]

static void Standard::Free ( const Standard_Address  thePtr )

static

Deallocates memory blocks.

Parameters

thePtr

- previously allocated memory block to be freed

Free() [2/2]

template<typename T >

static void Standard::Free ( T *&  thePtr )

inlinestatic

Template version of function Free(), nullifies the argument pointer.

Parameters

thePtr

- previously allocated memory block to be freed

FreeAligned() [1/2]

static void Standard::FreeAligned ( const Standard_Address  thePtrAligned )

static

Deallocates memory blocks.

Parameters

thePtrAligned

the memory block previously allocated with AllocateAligned()

FreeAligned() [2/2]

template<typename T >

static void Standard::FreeAligned ( T *&  thePtrAligned )

inlinestatic

Template version of function FreeAligned(), nullifies the argument pointer.

Parameters

thePtrAligned

the memory block previously allocated with AllocateAligned()

Purge()

static Standard_Integer Standard::Purge ( )

static

Deallocates the storage retained on the free list and clears the list. Returns non-zero if some memory has been actually freed.

Reallocate()

static Standard_Address Standard::Reallocate ( const Standard_Address  aStorage, const Standard_Size  aNewSize  )

static

Reallocates memory blocks aStorage - previously allocated memory block aNewSize - new size in bytes.
