</div><h2>Metadata Loading Errors</h2>
|
|
|
|
<p />The routines in this section are used to cope with errors
|
|
during metadata loading. Errors in metadata handling can
|
|
happen for many reason, and these include (this is not an
|
|
exhaustive list).
|
|
|
|
<ul>
|
|
<li>An assembly referenced is missing.
|
|
<li>Fields referenced are missing.
|
|
<li>Methods referenced are missing.
|
|
</li></li></li></ul>
|
|
|
|
<p />The <tt>mono_loader_set_*</tt> routines are invoked during
|
|
metadata loading to flag that an error has happened. The
|
|
class loading errros are flagged in a per-thread basis.
|
|
|
|
<p />In various spots in the runtime the
|
|
<tt>mono_loader_get_last_error</tt> routine is called to check
|
|
if there was a problem, and then errors are propagated upwards
|
|
on the stack until we reach a point where an exception can be
|
|
raised and no runtime locks are held.
|
|
|
|
<p />The <tt>mono_loader_error_prepare_exception</tt> takes a
|
|
<tt>MonoLoaderError</tt> structure (the value returned from
|
|
<tt>mono_loader_get_last_error</tt>), turns that into an
|
|
exception and clears the error condition from the current
|
|
thread.
