HostBufferBase

Fully qualified name: isaacsim::core::includes::HostBufferBase

template<typename T>
class HostBufferBase : public isaacsim::core::includes::Buffer<T>

Host (CPU) memory buffer implementation.

Manages a buffer of memory allocated in host RAM using std::vector. Provides a simple wrapper around std::vector with the Buffer interface.

Template Parameters:

T – The data type stored in the buffer

Public Functions

inline HostBufferBase(size_t size = 0)

Constructs a new host buffer.

Parameters:

size – [in] Initial size of the buffer in elements (default: 0)

inline virtual void resize(size_t size)

Resizes the host buffer.

Parameters:

size – [in] New size in number of elements

inline virtual void resize(size_t size, const T &val)

Resizes the host buffer and initializes new elements.

Parameters:

• size – [in] New size in number of elements

• val – [in] Value to initialize new elements with

inline virtual T *data() const

Gets a pointer to the host memory.

Returns:

Raw pointer to the host memory

inline virtual size_t size() const

Gets the current size of 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)

Public Members

std::vector<T> m_buffer

Underlying vector storing the data.

Protected Attributes

MemoryType m_memoryType

Type of memory where the buffer resides.
