fields.buffers.base.BufferBase.as_core

BufferBase.as_core() → _Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str]

Return the raw backend array object stored in this buffer.

This method provides direct access to the internal array-like object (e.g., numpy.ndarray, unyt.unyt_array, or h5py.Dataset) without any conversion or wrapping. It is useful for advanced users who need to access backend-specific methods or metadata not exposed through the generic buffer interface.

Unlike as_array(), this method returns the native format of the underlying backend, preserving units or lazy behavior if applicable.

Returns:

The unmodified internal array object stored in the buffer.

Return type:

ArrayLike
