public class UnoRuntime extends Object
The methods queryInterface and areSame delegate
calls to the implementing objects and are used instead of casts,
instanceof, ==, and equals.
For historic reasons, this class is not final, and has a
public constructor. These artifacts are considered mistakes,
which might be corrected in a future version of this class, so client code
should not rely on them.

It is guaranteed that every invocation of this method generates a new ID, which is unique within the VM. The quality of “world wide unique” will depend on the actual implementation, you should look at the source to determine if it meets your requirements.
Stringpublic static String generateOid(Object object)
It is guaranteed that subsequent calls to this method with the same Java object will give the same ID.
This method is generally of little use for client code. It should be considered a mistake that this method is published at all.

This method returns null in case the given UNO object
does not support the given UNO interface type (or is itself
null). Otherwise, a reference to a Java object implementing
the Java interface type corresponding to the given UNO interface is
returned. In the latter case, it is unspecified whether the returned
Java object is the same as the given object, or is another facet of that
UNO object.

ANY values for equality.
Two UNO values are equal if and only if they are of the same UNO type t, and they meet the following condition, depending on t:
any1 - a Java value representing a UNO ANY value.any2 - a Java value representing a UNO ANY value.true if and only if the two arguments represent

This is useful for members of parameterized type of instantiated
polymorphic struct types, as null is a valid value there
(and only there, for all types except ANY and interface
types).

no context has been set for the current thread.
The current context is thread local, which means that this method returns the context that was last set for this thread.

The current context is thread local. To support a stacking behaviour,
every function that sets the current context should reset it to the
original value when exiting (for example, within a finally
block).

Mappings are like bridges, except that with mappings one can only map in one direction. Mappings are here for compatibility with the binary UNO API. Mappings are implemented as wrappers around bridges.
