t.p.reflect : module documentation

Return the fully qualified name of a module, class, method or function. Classes and functions need to be module level ones to be correctly qualified.

Returns

(type: str.)

this is more documentation for myself than useful code.

Return full import path of a class.

Return the class or type of object 'obj'. Returns sensible result for oldstyle and newstyle instances and types.

Return a module given its name.

Get a fully named module-global object.

Import the given name as a module, then walk the stack to determine whether the failure was the module not existing, or some code in the module (for example a dependent import) failing. This can be helpful to determine whether any actual application code was run. For example, to distiguish administrative error (entering the wrong module name), from programmer error (writing buggy code in a module that fails to import).

Raises	Exception	if something bad happens. This can be any type of exception, since nobody knows what loading some arbitrary code might do.
	_NoModuleFound	if no module was found.

Retrieve a Python object by its fully qualified name from the global Python module namespace. The first part of the name, that describes a module, will be discovered and imported. Each subsequent part of the name is treated as the name of an attribute of the object specified by all of the name which came before it. For example, the fully-qualified name of this object is 'twisted.python.reflect.namedAny'.

Parameters	name	The name of the object to return. (type: str)
Returns	the Python object identified by 'name'.
Raises	InvalidName	If the name is an empty string, starts or ends with a '.', or is otherwise syntactically incorrect.
	ModuleNotFound	If the name is syntactically correct but the module it specifies cannot be imported because it does not appear to exist.
	ObjectNotFound	If the name is syntactically correct, includes at least one '.', but the module it specifies cannot be imported because it does not appear to exist.
	AttributeError	If an attribute of an object along the way cannot be accessed, or a module along the way is not found.

Helper function for safe_repr and safe_str.

safe_repr(anything) -> string

Returns a string representation of an object, or a string containing a traceback, if that object's __repr__ raised an exception.

safe_str(anything) -> string

Returns a string representation of an object, or a string containing a traceback, if that object's __str__ raised an exception.

allYourBase(classObj, baseClass=None) -> list of all base classes that are subclasses of baseClass, unless it is None, in which case all bases will be added.

A list of method names with a given prefix in a given class.

addMethodNamesToDict(classObj, dict, prefix, baseClass=None) -> dict this goes through 'classObj' (and its bases) and puts method names starting with 'prefix' in 'dict' with a value of 1. if baseClass isn't None, methods will only be added if classObj is-a baseClass

If the class in question has the methods 'prefix_methodname' and 'prefix_methodname2', the resulting dict should look something like: {"methodname": 1, "methodname2": 1}.

A list of methods with a given prefix on a given instance.

accumulateMethods(instance, dict, prefix) I recurse through the bases of instance.__class__, and add methods beginning with 'prefix' to 'dict', in the form of {'methodname':*instance*method_object}.

Accumulate all attributes of a given name in a class hierarchy into a single dictionary.

Assuming all class attributes of this name are dictionaries. If any of the dictionaries being accumulated have the same key, the one highest in the class heirarchy wins. (XXX: If "higest" means "closest to the starting class".)

Ex:

 class Soy:
   properties = {"taste": "bland"}

 class Plant:
   properties = {"colour": "green"}

 class Seaweed(Plant):
   pass

 class Lunch(Soy, Seaweed):
   properties = {"vegan": 1 }

 dct = {}

 accumulateClassDict(Lunch, "properties", dct)

 print dct

{"taste": "bland", "colour": "green", "vegan": 1}

Accumulate all attributes of a given name in a class heirarchy into a single list.

Assuming all class attributes of this name are lists.

An insanely CPU-intensive process for finding stuff.

Convert a name in the filesystem to the name of the Python module it is.

This is agressive about getting a module name back from a file; it will always return a string. Agressive means 'sometimes wrong'; it won't look at the Python path or try to do any error checking: don't use this method unless you already know that the filename you're talking about is a Python module.
