class `render::GpuUniformBufferMember`

template<class T>

Wrapper for a single member in an uniform buffer.

Public

void Set(const GpuBufferMappedScope &mappedRegion, const T &value, u32 arrayIndex = 0, u32 suballocationIndex = 0) const

Sets parameter value directly to mapped memory via a GpuMappedRegion.

mappedRegion: Active mapping containing the mapped memory pointer of the buffer in which to set the value.
value: Value to set.
arrayIndex: Index in the array (if parameter is an array).
suballocationIndex: Index of the sub-allocation in the uniform buffer to set the value for, if the buffer contains multiple sub-allocated buffers. Mapped region is assumed to point to the start of the buffer (i.e. first suballocation).

T Get(const GpuBufferMappedScope &mappedRegion, u32 arrayIndex = 0, u32 suballocationIndex = 0) const

Gets the parameter in the provided uniform buffer.

Caller is responsible for ensuring the uniform buffer contains this parameter.

mappedRegion: Active mapping containing the mapped memory pointer of the buffer from which to get the value.
arrayIndex: Index in the array to get the value for (if the parameter is an array).
suballocationIndex: Index of the sub-allocation in the uniform buffer to get the value for, if the buffer contains multiple sub-allocated buffers. Mapped region is assumed to point to the start of the buffer (i.e. first suballocation).

u32 CalculateParameterOffset(const SPtr<GpuBuffer> &buffer, u32 suballocationIndex, u32 arrayIndex) const

Calculates the byte offset for a parameter accounting for sub-allocations and array indices.

static void WriteTypedToMemory(void *destination, const GpuDataParameterTypeInformation &typeInformation, const void *source)

Writes typed data to memory with proper alignment/padding.

static void ReadTypedFromMemory(const void *source, const GpuDataParameterTypeInformation &typeInformation, void *destination)

Reads typed data to memory with proper alignment/padding.
