A nasty bug came about with releasing, as allLocks put locks into a new collection, and the iterator just removed them from that set instead of from the storage. This is now fixed, but the loop to do it is really damn complex. I'm not sure of the solution, but there should be something that is less confusing.</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/Map.html" title="class or interface in java.util">Map</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/InProcessLockingManager.html#lockTables">lockTables</A></B></CODE><BR> lockTable access by typeName stores Transactions or MemoryLocks</TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><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/geotools/data/InProcessLockingManager.html#InProcessLockingManager()">InProcessLockingManager</A></B>()</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><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>protected <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/util/Set.html" title="class or interface in java.util">Set</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/InProcessLockingManager.html#allLocks()">allLocks</A></B>()</CODE><BR> Set of all locks.</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/geotools/data/InProcessLockingManager.html#assertAccess(java.lang.String, java.lang.String, org.geotools.data.Transaction)">assertAccess</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> typeName, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> featureID, <A HREF="../../../org/geotools/data/Transaction.html" title="interface in org.geotools.data">Transaction</A> transaction)</CODE><BR> Checks mutability of featureID for this transaction. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../org/geotools/data/FeatureWriter.html" title="interface in org.geotools.data">FeatureWriter</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/InProcessLockingManager.html#checkedWriter(org.geotools.data.FeatureWriter, org.geotools.data.Transaction)">checkedWriter</A></B>(<A HREF="../../../org/geotools/data/FeatureWriter.html" title="interface in org.geotools.data">FeatureWriter</A> writer, <A HREF="../../../org/geotools/data/Transaction.html" title="interface in org.geotools.data">Transaction</A> transaction)</CODE><BR> Provides a wrapper on the provided writer that checks locks.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected InProcessLockingManager.Lock</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/InProcessLockingManager.html#createLock(org.geotools.data.Transaction, org.geotools.data.FeatureLock)">createLock</A></B>(<A HREF="../../../org/geotools/data/Transaction.html" title="interface in org.geotools.data">Transaction</A> transaction, <A HREF="../../../org/geotools/data/FeatureLock.html" title="interface in org.geotools.data">FeatureLock</A> featureLock)</CODE><BR> Creates the right sort of In-Process Lock.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../org/geotools/data/InProcessLockingManager.html#exists(java.lang.String)">exists</A></B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> authID)</CODE><BR> Implment lockExists. </TD></TR>⌨️ 快捷键说明
