getDebugFrame

lsstDebug.getDebugFrame(debugDisplay, name)

Attempt to extract a frame for displaying a product called name from the `debugDisplay variable.

Per the above, an instance of Info can return an arbitrary object (or nothing) as its display attribute. It is convenient – though not required – that it be a dictionary mapping data products to frame numbers, as shown in the lsstDebug.Info example. Given such a dictionary, this function extracts and returns the appropriate frame number. If debugDisplay is not a collection, or if name is not found within it, we return None.

Parameters:

debugDisplay : object

The contents of lsstDebug.Info(__name__).display.

name : str

The name of the data product to be displayed.

Returns:

frame : int

A frame number, or None.
