FastObj Class Reference

Detailed Description

Fast object with global pool.

The FastObj class uses global pool. So, the FastObj class may be used with polymorphic classes in contrast to FastObjT class. Any allocation/deallocation operations use mem_get_sized() and mem_put_sized() functions.

To use fast memory management your class should be derived from the FastObj class. See the example below.

    class MyClass: public omni::pool::FastObj {
      // ...
    };

    class Test: public MyClass {
      // ...
    };

    void f()
    {
      MyClass *p1 = new MyClass(); // mem_get_sized() used
      // ...
      delete p1; // mem_put_sized() used

      Test *p2 = new Test(); // mem_get_sized() used
      // ...
      delete p2; // mem_put_sized() used
    }

Member Function Documentation

void * operator new

(

size_t

buf_size

)

[static]

The memory allocation.

This operator allocates the buf_size bytes memory block using mem_get_sized() function.

Exceptions:

std::bad_alloc

If no memory is available.

Parameters:

[in]

buf_size

The memory block size.

Returns:

The memory block.

void * operator new	(	size_t	buf_size,
		const std::nothrow_t &
	)			[static]

The memory allocation.

This operator allocates the buf_size bytes memory block using mem_get_sized() function.

If there is no available memory, then this operator will return null pointer.

Parameters:

[in]

buf_size

The memory block size.

Returns:

The memory block or null.

void * operator new	(	size_t	buf_size,
		void *	p
	)			[static]

Placement new operator.

This operator is used only for correct overloading of other new operators. It uses global placement new operator.

Parameters:

[in]	buf_size	The memory block size.
[in]	p	The memory block.

Returns:

The memory block.

void operator delete

(

void *

buf

)

[static]

The memory deallocation.

This operator deallocates the buf memory block using mem_put_sized() function.

Parameters:

[in]

buf

The memory block.

void operator delete	(	void *	buf,
		const std::nothrow_t &
	)			[static]

The memory deallocation.

This operator deallocates the buf memory block using mem_put_sized() function.

Parameters:

[in]

buf

The memory block.

void operator delete	(	void *	buf,
		void *	p
	)			[static]

Placement delete operator?

This operator is used only for correct overloading of other delete operators. It uses global placement delete operator.

Parameters:

[in]	buf	The memory block?
[in]	p	The memory block?
