lsstDebug.Info Class Reference

 _modname
 

Detailed Description

An object cognisant of debugging parameters appropriate for module
``modname``.

Any request for a value will return False unless that value has
been set, either in the module or as an attribute of this object.

E.g.

.. code-block:: python

    import lsstDebug

    display = lsstDebug.Info(__name__).display

will set display to `False`, unless display has been set with

.. code-block:: python

    lsstDebug.Info(__name__).display = True

Why is this interesting?  Because you can replace `lsstDebug.Info` with
your own version, e.g.

.. code-block:: python

    import lsstDebug

    def DebugInfo(name):
        # N.b. lsstDebug.Info(name) would call us recursively
        di = lsstDebug.getInfo(name)
        if name == "foo":
            di.display = dict(repair=1, background=2, calibrate=3)

        return di

    lsstDebug.Info = DebugInfo

Parameters
----------
modname : `str`
    Module name.

Raises
------
KeyError
    Raised if ``modname`` is not loaded.
