Buffer

Fully qualified name: isaacsim::core::includes::Buffer

template<typename T>
class Buffer

Abstract base class for memory buffer management.

Provides a common interface for managing memory buffers, whether they reside in host (CPU) or device (GPU) memory. This class defines the basic operations that all buffer implementations must support.

Note

All derived classes must implement resize(), data(), and size() functions

Template Parameters:

T – The data type stored in the buffer

Subclassed by isaacsim::core::includes::DeviceBufferBase< T >, isaacsim::core::includes::GenericBufferBase< T >, isaacsim::core::includes::HostBufferBase< T >

Public Functions

virtual ~Buffer() = default

Virtual destructor for proper cleanup of derived classes.

virtual void resize(size_t size) = 0

Resizes the buffer to hold the specified number of elements.

Parameters:

size – [in] The new size of the buffer in number of elements

virtual T *data() const = 0

Gets a pointer to the buffer’s data.

Returns:

Pointer to the buffer’s data

virtual size_t size() const = 0

Gets the number of elements in the buffer.

Returns:

Number of elements in the buffer

inline size_t sizeofType() const

Gets the size of a single element in bytes.

Returns:

Size of type T in bytes

inline size_t sizeInBytes() const

Gets the total size of the buffer in bytes.

Returns:

Total size of the buffer in bytes

inline MemoryType type() const

Gets the memory type of the buffer.

Returns:

Memory type (Host or Device)

Protected Attributes

MemoryType m_memoryType

Type of memory where the buffer resides.
