template<typename ElementType >

static ElementType* mitk::MemoryUtilities::AllocateElements	(	vcl_size_t	numberOfElements,
		bool	noThrow = `false`
	)

inlinestatic

Allocates an array of a given number of elements. Each element has a size of sizeof(ElementType). The function returns NULL, if the array could not be allocated.

Parameters

numberOfElements	the number of elements of the array
noThrow	if set to false, an exception is thrown if memory allocation fails. If set to true, a itk::MemoryAllocationError is thrown

Returns: a pointer to the allocated array. If noThrow == true, NULL is returned if memory allocation failed.

template<typename ElementType >

static void mitk::MemoryUtilities::DeleteElements ( ElementType * elements )

inlinestatic

Deletes an array of elements previously allocated by AllocateElements.

Parameters

elements the array to delete. Not that NULL is an accepted value.

vcl_size_t mitk::MemoryUtilities::GetProcessMemoryUsage ( )

static

Returns the memory usage of the current process in bytes. On linux, this refers to the virtual memory allocated by the process (the VIRT column in top). On windows, this refery to the size in bytes of the working set pages (the "Speicherauslastung" column in the task manager).
