Slices

Slice management from annnet.core._Slices.

Use G.slices and the AnnNet slice methods for slice workflows. Direct imports from underscore modules follow the internal API policy.

annnet.core._Slices.SliceManager

Namespace for all slice operations, exposed as G.slices.

State (_slices, _current_slice, _default_slice, slice_edge_weights) lives on AnnNet because it is accessed pervasively in core graph methods; this class is the user-facing API surface over that state.

Functions

add

add(slice_id, **attributes)

Create a new empty slice.

Parameters:

Name	Type	Description	Default
slice_id	str		required

Raises:

Type	Description
ValueError	If attempting to remove the internal default slice.
KeyError	If the slice does not exist.

add_edge_to_slice

add_edge_to_slice(lid, eid)

Attach an existing edge to a slice (no weight changes).

Parameters:

Name	Type	Description	Default
lid	str		required
eid	str		required

Raises:

Type	Description
KeyError	If the slice or edge does not exist.

add_edges

add_edges(slice_id, edge_ids)

Attach many existing edges to a slice and include their incident vertices.

get_slices_dict

get_slices_dict(include_default=True)

Return the raw slice_id → SliceRecord mapping (distinct from list).

list

list(include_default=True)

Slice IDs as a list.

add_vertex_to_slice

add_vertex_to_slice(lid, vid)

Attach an existing vertex to a slice.

Raises:

Type	Description
