<hr><a name="_details"></a><h2>Detailed Description</h2>
<a class="el" href="classUObject.html">UObject</a> is the common ICU "boilerplate" class.
<p>
<a class="el" href="classUObject.html">UObject</a> inherits <a class="el" href="classUMemory.html">UMemory</a> (starting with ICU 2.4), and all other public ICU C++ classes are derived from <a class="el" href="classUObject.html">UObject</a> (starting with ICU 2.2).<p>
<a class="el" href="classUObject.html">UObject</a> contains common virtual functions like for ICU's "poor man's RTTI". It does not contain default implementations of virtual methods like getDynamicClassID to allow derived classes such as <a class="el" href="classFormat.html">Format</a> to declare these as pure virtual.<p>
The clone() function is not available in <a class="el" href="classUObject.html">UObject</a> 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, and all subclasses within that service class tree return a pointer to the service base class (which itself is a subclass of <a class="el" href="classUObject.html">UObject</a>). This is because some compilers do not support covariant (same-as-this) return types; cast to the appropriate subclass if necessary.<p>
