_get_raw_data(self)

This is determined by walking through the bases until finding one that has at least the same number of bytes as self, plus the heapsize. This may be the immediate .base but is not always. This is used primarily for variable-length array support which needs to be able to find the heap (the raw data may be larger than nbytes + heapsize if it contains a gap or padding).

May return None if no array resembling the "raw data" according to the stated criteria can be found.

Returns the base array of self that "raw data array" that is the array in the format that it was first read from a file before it was sliced or viewed as a different type in any way.

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
