CopyFromTempBuffer()

static void rtctk::componentFramework::detail::UserTypeHandler< T >::CopyFromTempBuffer ( BufferType & buffer, const std::shared_ptr< TempBufferType > & temp_buffer, size_t offset, size_t count )

staticdelete

Copy data from the temporary buffer into the original buffer.

This method must only be implemented if USES_TEMP_BUFFER is true, i.e for types that require temporary buffers.

Note

The buffers are treated as flat arrays.

Parameters

[out]	buffer	The buffer object to copy the data into.
[in]	temp_buffer	The temporary buffer object from which to copy the data.
[in]	offset	The index of the first element in buffer that will be written to.
[in]	count	The number of elements to copy.

CopyToTempBuffer()

static void rtctk::componentFramework::detail::UserTypeHandler< T >::CopyToTempBuffer ( const BufferType & buffer, std::shared_ptr< TempBufferType > & temp_buffer, size_t offset, size_t count )

staticdelete

Copy data from the original buffer into the temporary buffer.

This method must only be implemented if USES_TEMP_BUFFER is true, i.e for types that require temporary buffers.

Note

The buffers are treated as flat arrays.

Parameters

[in]	buffer	The buffer object from which to copy the data.
[out]	temp_buffer	The temporary buffer object to copy data into.
[in]	offset	The index of the first element in buffer to start copying.
[in]	count	The number of elements to copy.

GetShape() [1/2]

static RtcVectorUInt64 rtctk::componentFramework::detail::UserTypeHandler< T >::GetShape ( const BufferType & buffer )

inlinestatic

Returns the shape of a buffer object.

Parameters

[in]

buffer

The buffer object for which the shape is calculated.

Returns

A list of unsigned integers indicating the number of elements for each dimension. The size of the list must equal the number of dimensions, i.e. the rank. For example, a scalar will have zero entries, a vector one entry, a matrix two.

GetShape() [2/2]

template<typename T, std::size_t N, std::size_t M>

static RtcVectorUInt64 rtctk::componentFramework::detail::UserTypeHandler< std::array< std::array< T, M >, N > >::GetShape ( const BufferType & buffer )

inlinestatic

MakeSpan() [1/4]

static gsl::span< ElementType > rtctk::componentFramework::detail::UserTypeHandler< T >::MakeSpan ( BufferType & buffer )

inlinestatic

Creates a span from a buffer object.

Parameters

[in]

buffer

The buffer object from which to create the span.

Returns

A span object accessing the buffer object's underlying elements.

MakeSpan() [2/4]

template<typename T, std::size_t N, std::size_t M>

static gsl::span< ElementType > rtctk::componentFramework::detail::UserTypeHandler< std::array< std::array< T, M >, N > >::MakeSpan ( BufferType & buffer )

inlinestatic

MakeSpan() [3/4]

static gsl::span< const ElementType > rtctk::componentFramework::detail::UserTypeHandler< T >::MakeSpan ( const BufferType & buffer )

inlinestatic

Creates a span from a read-only buffer object.

Parameters

[in]

buffer

The buffer object from which to create the span.

Returns

A span object accessing the buffer object's underlying elements.

MakeSpan() [4/4]

template<typename T, std::size_t N, std::size_t M>

static gsl::span< const ElementType > rtctk::componentFramework::detail::UserTypeHandler< std::array< std::array< T, M >, N > >::MakeSpan ( const BufferType & buffer )

inlinestatic

ResizeBuffer() [1/2]

static bool rtctk::componentFramework::detail::UserTypeHandler< T >::ResizeBuffer ( BufferType & buffer, const RtcVectorUInt64 & shape )

inlinestatic

Tries to resize the buffer to the given shape.

If possible, the buffer should be resized to contain enough space to hold the total number of elements indicated by the shape. If it is not possible to resize to the space required, then no resize should occur and false should be returned. In the case the buffer is already the correct size, resizing can be skipped and true returned, to indicate the buffer is OK.

Parameters

[in,out]	buffer	The buffer object to be resized.
[in]	shape	The shape the buffer should be resized to.

Returns

true if the buffer size is correct or could be resized, and false otherwise.

ResizeBuffer() [2/2]

template<typename T, std::size_t N, std::size_t M>

static bool rtctk::componentFramework::detail::UserTypeHandler< std::array< std::array< T, M >, N > >::ResizeBuffer ( BufferType & buffer, const RtcVectorUInt64 & shape )
