<h2>Detailed Description</h2>

<p>\class ErrorCache error.h Soprano/Error/ErrorCache
</p>
<p>
Core class of %Soprano's exception system.
</p>
<p>
The ErrorCache caches Error instances for different threads.
Each thread has its own last error. This mechanism tries to
replace the missing exceptions for methods that do not return
an error code or another value that can state the success of the
method's operation.
