__call__

__call__(url: str, registry: ObjectStoreRegistry) -> ManifestStore

Parse the metadata and byte offsets from a given HDF5/NetCDF4 file to produce a VirtualiZarr ManifestStore.

Parameters:

• url (str) –

  The URL of the input HDF5/NetCDF4 file (e.g., "s3://bucket/store.zarr").

• registry (ObjectStoreRegistry) –

  An ObjectStoreRegistry for resolving urls and reading data.

Returns:

• ManifestStore –

  A ManifestStore which provides a Zarr representation of the parsed file.

__init__

__init__(
    group: str | None = None,
    drop_variables: Iterable[str] | None = None,
    reader_factory: ReaderFactory = BlockStoreReader,
)

Instantiate a parser that can be used to virtualize HDF5/NetCDF4 files using the __call__ method.

Parameters:

• group (str | None, default: None ) –

  Name of the group within the HDF5 file to virtualize.

• drop_variables (Iterable[str] | None, default: None ) –

  Variables in the file that will be ignored when creating the ManifestStore (default: None, do not ignore any variables).

• reader_factory (ReaderFactory, default: BlockStoreReader ) –

  A callable that creates a file-like reader from a store and path. Must return an object implementing the ReadableFile protocol. Default is BlockStoreReader.
