Singleton Class

Singleton classes represent a UNO singleton.

Static

Singleton classes in ooo.lo and ooo.csslo namespaces are static abstract classes. As of version 2.0.0 the ooo.csslo namespace is deprecated. Use the ooo.lo namespace instead.

Singleton classes in ooo.lo and ooo.csslo namespaces are the same classes. As of version 2.0.0 the ooo.cssdyn namespace is deprecated. Use the ooo.dyn namespace instead.

Example:

from ooo.lo.beans.the_introspection import theIntrospection as LotheIntrospection
from ooo.csslo.beans import theIntrospection as CsstheIntrospection
same = LotheIntrospection is CsstheIntrospection
assert same == True

Dynamic

Singleton classes in ooo.dyn and ooo.cssdyn namespaces are dynamic classes and are changed during runtime.

Example dynamic:

from ooo.cssdyn.beans import theIntrospection
singleton = theIntrospection()
assert type(singleton).__name__ == "pyuno"
im_name = "com.sun.star.comp.stoc.Introspection"
assert singleton.getImplementationName() == im_name

Singleton classes in ooo.dyn and ooo.cssdyn namespaces are dynamic classes and are changed during runtime

Note

Dynamic singleton classes have a dynamic constructor.

This means ooo.cssdyn.beans.theIntrospection is a function at runtime

whereas singleton = theIntrospection() is an instance of a UNO class.
