Constructor & Destructor Documentation

template<typename T>

CE_BufferDevice< T >::CE_BufferDevice ( )

inline

Empty buffer constructor.

Definition at line 28 of file CE_BufferDevice.h.

template<typename T>

CE_BufferDevice< T >::CE_BufferDevice ( exint  size )

inline

Allocated an uninitialized buffer of specified size (if > 0).

Definition at line 31 of file CE_BufferDevice.h.

template<typename T>

CE_BufferDevice< T >::CE_BufferDevice ( cl::Buffer &&  buf, exint  size = -1  )

inline

Initialize from a raw cl::Buffer, which this object now owns. If size is not provided, calc from the buffer size and type. The input cl::Buffer is empty after this call.

Definition at line 42 of file CE_BufferDevice.h.

template<typename T>

CE_BufferDevice< T >::CE_BufferDevice ( const CE_BufferDevice< T > &  b )

delete

No copy constructor.

Member Function Documentation

template<typename T>

template<typename V >

CE_ArrayView<V> CE_BufferDevice< T >::arrayView ( )

inline

Definition at line 78 of file CE_BufferDevice.h.

template<typename T>

template<typename V >

const CE_ArrayView<V> CE_BufferDevice< T >::arrayView ( ) const

inline

Definition at line 94 of file CE_BufferDevice.h.

template<typename T>

const cl::Buffer& CE_BufferDevice< T >::buffer ( ) const

inline

Returns the underlying OpenCL buffer. Note: This is meant for directly passing to OpenCL functions. holding ownership over long times.

Definition at line 156 of file CE_BufferDevice.h.

template<typename T>

void CE_BufferDevice< T >::copyFrom	(	const CE_BufferDevice< T > &	b,
		exint	len = -1
	)

Copy from the input buffer. If len >= 0, only len elements are copied. NOTE: This object must already be initialized to a buffer of sufficient size.

Definition at line 272 of file CE_BufferDevice.h.

template<typename T >

SYS_FORCE_INLINE void CE_BufferDevice< T >::init

(

exint

size

)

Initialize to given size. NOTE- values are undefined.

Definition at line 196 of file CE_BufferDevice.h.

template<typename T>

void CE_BufferDevice< T >::initFromArray	(	const UT_Array< T > &	src,
		exint	len = -1,
		bool	block = true
	)

Initialize from a UT_Array. If len >= 0, only len elements are copied.

Definition at line 203 of file CE_BufferDevice.h.

template<typename T>

void CE_BufferDevice< T >::initFromData	(	const T *	data,
		exint	nelem,
		bool	block = true
	)

Initialize from raw data block of T elements of length nelem.

Definition at line 240 of file CE_BufferDevice.h.

template<typename T>

bool CE_BufferDevice< T >::isEmpty ( ) const

inline

Returns true iff there are no occupied elements in the buffer.

Definition at line 151 of file CE_BufferDevice.h.

template<typename T>

void CE_BufferDevice< T >::matchAndCopyToArray	(	UT_Array< T > &	dst,
		exint	len = -1,
		bool	block = true
	)		const

Resize the provided UT_Array to fit and copy this vector's data there. If len >= 0 then only len elements are copied.

Definition at line 221 of file CE_BufferDevice.h.

template<typename T>

cl::Buffer CE_BufferDevice< T >::release ( )

inline

Release and return the underlying buffer without deleting, after which this object is empty (similar to unique_ptr).

Definition at line 101 of file CE_BufferDevice.h.

template<typename T>

void CE_BufferDevice< T >::reset ( cl::Buffer &&  buf, exint  size = -1  )

inline

Reset to own the provided raw cl::Buffer. If size is not provided, calc from the buffer size and type. The input cl::Buffer is empty after this call.

Definition at line 112 of file CE_BufferDevice.h.

template<typename T>

exint CE_BufferDevice< T >::size ( ) const

inline

Returns the buffer length.

Definition at line 148 of file CE_BufferDevice.h.
