_getfield_is_safe(oldtype, newtype, offset)

As in _view_is_safe, we need to check that memory containing objects is not reinterpreted as a non-object datatype and vice versa.

Parameters

oldtype : data-type

Data type of the original ndarray.

newtype : data-type

Data type of the field being accessed by ndarray.getfield

offset : int

Offset of the field being accessed by ndarray.getfield

Raises

TypeError

If the field access is invalid

Checks safety of getfield for object arrays.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
