When instantiating a FITS diff object, the first two arguments are always the two objects to diff (two FITS files, two FITS headers, etc.). Instantiating a _BaseDiff
also causes the diff itself to be executed. The returned _BaseDiff
instance has a number of attribute that describe the results of the diff operation.
The most basic attribute, present on all _BaseDiff
instances, is .identical
which is :None:None:`True` if the two objects being compared are identical according to the diff method for objects of that type.
Base class for all FITS diff objects.
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
