Overview of different classes

Create an actor

The class IActor implements an interface to emulate a function.

>>> import openalea.core as core
>>> a = openalea.core.actor.IActor()

Create a new package

>>> p = core.Package

The package manager

The module openalea.core.pkgmanager contains a class to manage the packages, which is called PackageManager.

>>> pm = pkgmanager.PackageManager()
>>> pm.init(verbose=False)

The PackageManager is a Dictionary of Packages. You can access to its keys using the standard dict methods. If you want to access to a particular Package, use the packageManager instance as a dictionary. r instance:

>>> pm.keys()
>>> pm['openalea.math']

that returns a list of nodes. To access to a particular node, use:

>>> pm['openalea.math']['floor']
<openalea.core.node.NodeFactory object at 0x936906c>

The floor node exists in the openalea.math package. The node floor is managed through a NodeFactory.
