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
theSizebytes to allocate
theAlignalignment 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
thePtrAlignedthe 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
thePtrAlignedthe 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.
