System properties are used to configure these options.This chapter describes the configurable analysis options.</p><p>The analysis options have two main purposes. First, they allow youto inform <span class="application">FindBugs</span> about the meaning of methods in your application,so that it can produce more accurate results, or produce fewerfalse warnings. Second, they allow you to configure the precisionof the analysis performed. Reducing analysis precision can savememory and analysis time, at the expense of missing some real bugs,or producing more false warnings.</p><p>The analysis options are set using the <span><strong class="command">-property</strong></span>command line option.

Specifying these methods allows the null pointer dereference bug detector to avoid reporting false warnings for values which are checked by assertion methods.</td></tr><tr><td align="left">findbugs.de.comment</td><td align="left">true or false</td><td align="left">If true, the DroppedException detector scans source code for empty catch blocks for a comment, and if one is found, does not report a warning.</td></tr><tr><td align="left">findbugs.maskedfields.locals</td><td align="left">true or false</td><td align="left">If true, emit low priority warnings for local variables which obscure fields.

Default is false. Note that enabling this property will very likely cause a large number of false warnings to be produced.)</td></tr><tr><td align="left">findbugs.refcomp.reportAll</td><td align="left">true or false</td><td align="left">If true, all suspicious reference comparisons using the == and != operators are reported.

Default is false.</td></tr><tr><td align="left">findbugs.sf.comment</td><td align="left">true or false</td><td align="left">If true, the SwitchFallthrough detector will only report warnings for cases where the source code does not have a comment containing the words "fall" or "nobreak". (An accurate source path must be used for this feature to work correctly.) This helps find cases where the switch fallthrough is likely to be unintentional.</td></tr></tbody></table></div></div><br class="table-break"></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="filter.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="annotations.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 8.
