Detailed Description

UObject is the common ICU "boilerplate" class.

UObject inherits UMemory (starting with ICU 2.4), and all other public ICU C++ classes are derived from UObject (starting with ICU 2.2).

UObject contains common virtual functions, in particular a virtual destructor.

The clone() function is not available in UObject because it is not implemented by all ICU classes. Many ICU services provide a clone() function for their class trees, defined on the service's C++ base class (which itself is a subclass of UObject).

Stable:
ICU 2.2

ICU4C "poor man's RTTI", returns a UClassID for the actual ICU class.

The base class implementation returns a dummy value.

Use compiler RTTI rather than ICU's "poor man's RTTI". Since ICU 4.6, new ICU C++ class hierarchies do not implement "poor man's RTTI".

ICU 2.2
