Rx::Interop::Runtime30::IMemory2DAccess Class Reference

Detailed Description

Interface for 2D memory read operations.

Inherited by Rx::Interop::Runtime30::IMemory2D.

Public Member Functions
virtual size_t	GetElementSize () const =0
	Gets the element size. The memory block is made up of blocks of the given number of bytes. The function Length() returns the number of elements in the memory block, where each element is of the size given in GetElementSize(). For example, an array of 10 doubles has element size 8 and length 10. More...
virtual const void *	GetPointer () const =0
	Gets the pointer to memory. More...
virtual void	GetSize (size_t &nRows, size_t &nCols) const =0
	Gets the number of elements in the memory block. The total number of bytes allocated by the memory block is given by the nRows times nCols times the element size. More...
virtual bool	IsValid () const =0
	Query if this object is valid. This function returns also true if the object itself is valid but the memory block has size zero. More...

GetElementSize()

virtual size_t Rx::Interop::Runtime30::IMemory2DAccess::GetElementSize ( ) const

pure virtual

Gets the element size. The memory block is made up of blocks of the given number of bytes. The function Length() returns the number of elements in the memory block, where each element is of the size given in GetElementSize(). For example, an array of 10 doubles has element size 8 and length 10.

Returns

The element size in bytes.

Implemented in Rx::CRxArray2DBase< TValue >, Rx::CRxArray2DDouble, and Rx::CRxArray2DInt.

GetPointer()

virtual const void* Rx::Interop::Runtime30::IMemory2DAccess::GetPointer ( ) const

pure virtual

Gets the pointer to memory.

Returns

The pointer to memory.

Implemented in Rx::CRxArray2DBase< TValue >, Rx::CRxArray2DDouble, and Rx::CRxArray2DInt.

GetSize()

virtual void Rx::Interop::Runtime30::IMemory2DAccess::GetSize ( size_t &  nRows, size_t &  nCols  ) const

pure virtual

Gets the number of elements in the memory block. The total number of bytes allocated by the memory block is given by the nRows times nCols times the element size.

Parameters

nRows	[out] The number of rows.
nCols	[out] The number of columns.

Implemented in Rx::CRxArray2DBase< TValue >, Rx::CRxArray2DDouble, and Rx::CRxArray2DInt.

IsValid()

virtual bool Rx::Interop::Runtime30::IMemory2DAccess::IsValid ( ) const

pure virtual

Query if this object is valid. This function returns also true if the object itself is valid but the memory block has size zero.

Returns

True if valid, false if not.

Implemented in Rx::CRxArray2DBase< TValue >, Rx::CRxArray2DDouble, and Rx::CRxArray2DInt.
