anndata.experimental.ReadCallback

protocol anndata.experimental.ReadCallback

typing.Protocol.

Classes that implement this protocol must have the following methods / attributes:

__call__(read_func, elem_name, elem, *, iospec)

Callback used in anndata.experimental.read_dispatched() to customize reading an element from a store.

Parameters:

read_func Read[TypeVar(S_co, bound= Array | Dataset | Group | Group, covariant=True), TypeVar(RWAble, bound= DataFrame | number | str | ndarray | MaskedArray | csr_matrix | csc_matrix | csr_array | csc_array | Dataset | Array | ZappyArray | CSRDataset | CSCDataset | Array | ndarray | spmatrix | Array | dict[str, AxisStorable] | list[AxisStorable] | AnnData | Categorical | ExtensionArray)]

anndata.io.read_elem() function to call to read the current element given the iospec.

elem_name str

The key to read in from the group.

elem Array | Dataset | Group | Group

The element to read from.

iospec IOSpec

Internal AnnData encoding specification for the element.

Return type:

TypeVar(RWAble, bound= DataFrame | number | str | ndarray | MaskedArray | csr_matrix | csc_matrix | csr_array | csc_array | Dataset | Array | ZappyArray | CSRDataset | CSCDataset | Array | ndarray | spmatrix | Array | dict[str, AxisStorable] | list[AxisStorable] | AnnData | Categorical | ExtensionArray)

Returns:

The element read from the store.
