|
This package is the root package of the govmomi library.
|
|
|
|
The library is structured as follows:
|
|
|
|
Package vim25
|
|
|
|
The minimal usable functionality is available through the vim25 package.
|
|
It contains subpackages that contain generated types, managed objects, and all
|
|
available methods. The vim25 package is entirely independent of the other
|
|
packages in the govmomi tree -- it has no dependencies on its peers.
|
|
|
|
The vim25 package itself contains a client structure that is
|
|
passed around throughout the entire library. It abstracts a session and its
|
|
immutable state. See the vim25 package for more information.
|
|
|
|
Package session
|
|
|
|
The session package contains an abstraction for the session manager that allows
|
|
a user to login and logout. It also provides access to the current session
|
|
(i.e. to determine if the user is in fact logged in)
|
|
|
|
Package object
|
|
|
|
The object package contains wrappers for a selection of managed objects. The
|
|
constructors of these objects all take a *vim25.Client, which they pass along
|
|
to derived objects, if applicable.
|
|
|
|
Package govc
|
|
|
|
The govc package contains the govc CLI. The code in this tree is not intended
|
|
to be used as a library. Any functionality that govc contains that _could_ be
|
|
used as a library function but isn't, _should_ live in a root level package.
|
|
|
|
Other packages
|
|
|
|
Other packages, such as "event", "guest", or "license", provide wrappers for
|
|
the respective subsystems. They are typically not needed in normal workflows so
|
|
are kept outside the object package.
