<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">SizeExpression's toString method outputs misleading results.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The toString implementation assumes that the implementation has the computed size on the LHS whereas toSqlString (and accordingly the op that is passed by the Restrictions.sizeXX methods) is implemented with the computed size on the RHS.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">This leads to confusing results for users when printing out criterion.toString values, as they appear to be saying roughly the opposite of what they are being asked to do.</p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">As a user I would expect the following test to pass:</p>
<div class="code panel" style="border-width: 1px;; border: 1px solid #ccc; background: #f5f5f5; font-size: 12px; line-height: 1.333; font-family: monospace; border: 1px solid #ccc; -moz-border-radius: 3px 3px 3px 3px; border-radius: 3px 3px 3px 3px; margin: 9px 0">
<div class="codeContent panelContent" style="padding: 9px 12px">
<pre class="code-java" style="margin: 10px 0 0 0; max-height: 30em; overflow: auto; white-space: pre-wrap; word-wrap: normal">
assertEquals(<span class="code-quote" style="color: #009100">"prop.size>=1"</span>, Restrictions.sizeGe(<span class="code-quote" style="color: #009100">"prop"</span>, 1).toString());
</pre>
</div>
</div>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">However it fails with:</p>
<div class="code panel" style="border-width: 1px;; border: 1px solid #ccc; background: #f5f5f5; font-size: 12px; line-height: 1.333; font-family: monospace; border: 1px solid #ccc; -moz-border-radius: 3px 3px 3px 3px; border-radius: 3px 3px 3px 3px; margin: 9px 0">
<div class="codeContent panelContent" style="padding: 9px 12px">
<pre class="code-java" style="margin: 10px 0 0 0; max-height: 30em; overflow: auto; white-space: pre-wrap; word-wrap: normal">
org.junit.ComparisonFailure:
Expected :prop.size>=1
Actual :prop.size<=1
</pre>
</div>
</div>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The lowest impact change would be to alter toString to emit the same order as toSqlString, so the following test would pass:</p>
