The verification should conform with a certain pass as described in The Java Virtual Machine Specification, 2nd edition. This book describes four passes. Pass one means loading the class and verifying a few static constraints. Pass two actually verifies some other constraints that could enforce loading in referenced class files. Pass three is the first pass that actually checks constraints in the code array of a method in the class file; it has two parts with the first verifying static constraints and the second part verifying structural constraints (where a data flow analysis is used for). The fourth pass, finally, performs checks that can only be done at run-time. JustIce does not have a run-time pass, but certain constraints that are usually delayed until run-time for performance reasons are also checked during the second part of pass three. PassVerifier instances perform caching. That means, if you really want a new verification run of a certain pass you must use a new instance of a given PassVerifier.<P><DL><DT><B>Version: </B><DD>$Id: PassVerifier.java,v 1.1.1.1 2001/10/29 20:00:31 jvanzyl Exp $</DD><DT><B>Author: </B><DD><A HREF="http://www.inf.fu-berlin.de/~ehaase"/>Enver Haase</A></DD><DT><B>See Also: </B><DD><A HREF="../../../../org/apache/bcel/verifier/Verifier.html"><CODE>Verifier</CODE></A>, <A HREF="../../../../org/apache/bcel/verifier/PassVerifier.html#verify()"><CODE>verify()</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../../org/apache/bcel/verifier/PassVerifier.html#PassVerifier()">PassVerifier</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/apache/bcel/verifier/PassVerifier.html#addMessage(java.lang.String)">addMessage</A></B>(java.lang.String message)</CODE><BR> This method adds a (warning) message to the message pool of this PassVerifier.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>abstract <A HREF="../../../../org/apache/bcel/verifier/VerificationResult.html">VerificationResult</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/apache/bcel/verifier/PassVerifier.html#do_verify()">do_verify</A></B>()</CODE><BR> Does the real verification work, uncached.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/apache/bcel/verifier/PassVerifier.html#getMessages()">getMessages</A></B>()</CODE><BR> Returns the (warning) messages that this PassVerifier accumulated during its do_verify()ing work.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../../org/apache/bcel/verifier/VerificationResult.html">VerificationResult</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../org/apache/bcel/verifier/PassVerifier.html#verify()">verify</A></B>()</CODE><BR> This method runs a verification pass conforming to the Java Virtual Machine Specification, 2nd edition, on a class file.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.lang.Object"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.lang.Object</B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE>clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait</CODE></TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><A NAME="constructor_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Constructor Detail</B></FONT></TD></TR></TABLE><A NAME="PassVerifier()"><!-- --></A><H3>PassVerifier</H3><PRE>public <B>PassVerifier</B>()</PRE><DL></DL><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="verify()"><!-- --></A><H3>verify</H3><PRE>public <A HREF="../../../../org/apache/bcel/verifier/VerificationResult.html">VerificationResult</A> <B>verify</B>()</PRE><DL><DD>This method runs a verification pass conforming to the Java Virtual Machine Specification, 2nd edition, on a class file.
