This value is referred to as the member key. The key value may be determined either by the member value itself, which defines a Set, or by external association with the member when the member is first added, which defines a Map. The KeyedCollection type inherits all standard behavior of Collection. The KeyedCollection type is not itself creatable; it only serves as a common supertype for Set and Map collection types. The keyed collection type establishes the common behavior shared by both Set and Map. Standard options are provided to declare ordering of members in the collection.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== 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> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/collections/KeyedCollection.html#at(java.lang.Object)">at</A></B>(java.lang.Object aKey)</CODE><BR> The at: message returns the existing member of the collection which matches the key value passed as its argument, or nil if there is no key value in the collection which matches.</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="../../swarm/collections/KeyedCollection.html#containsKey(java.lang.Object)">containsKey</A></B>(java.lang.Object aKey)</CODE><BR> The containsKey: message returns true if the key value passed as its argument is contained in the collection, and false otherwise.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/collections/KeyedCollection.html#createIndex$fromMember(swarm.defobj.Zone, java.lang.Object)">createIndex$fromMember</A></B>(<A HREF="../../swarm/defobj/Zone.html">Zone</A> aZone, java.lang.Object anObject)</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../swarm/collections/KeyedCollection.html#removeKey(java.lang.Object)">removeKey</A></B>(java.lang.Object aKey)</CODE><BR> The removeKey: message removes a member matching a key value from the collection, and returns the member just removed.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_swarm.collections.Collection"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface swarm.collections.<A HREF="../../swarm/collections/Collection.html">Collection</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/collections/Collection.html#allSameClass()">allSameClass</A>, <A HREF="../../swarm/collections/Collection.html#begin(swarm.defobj.Zone)">begin</A>, <A HREF="../../swarm/collections/Collection.html#beginPermuted(swarm.defobj.Zone)">beginPermuted</A>, <A HREF="../../swarm/collections/Collection.html#contains(java.lang.Object)">contains</A>, <A HREF="../../swarm/collections/Collection.html#copy(swarm.defobj.Zone)">copy</A>, <A HREF="../../swarm/collections/Collection.html#deleteAll()">deleteAll</A>, <A HREF="../../swarm/collections/Collection.html#getCount()">getCount</A>, <A HREF="../../swarm/collections/Collection.html#getReplaceOnly()">getReplaceOnly</A>, <A HREF="../../swarm/collections/Collection.html#remove(java.lang.Object)">remove</A>, <A HREF="../../swarm/collections/Collection.html#removeAll()">removeAll</A></CODE></TD></TR></TABLE> <A NAME="methods_inherited_from_class_swarm.collections.ForEachKey"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface swarm.collections.<A HREF="../../swarm/collections/ForEachKey.html">ForEachKey</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/collections/ForEachKey.html#forEachKey(swarm.Selector)">forEachKey</A>, <A HREF="../../swarm/collections/ForEachKey.html#forEachKey(swarm.Selector, java.lang.Object)">forEachKey</A>, <A HREF="../../swarm/collections/ForEachKey.html#forEachKey(swarm.Selector, java.lang.Object, java.lang.Object)">forEachKey</A>, <A HREF="../../swarm/collections/ForEachKey.html#forEachKey(swarm.Selector, java.lang.Object, java.lang.Object, java.lang.Object)">forEachKey</A></CODE></TD></TR></TABLE> <A NAME="methods_inherited_from_class_swarm.defobj.Drop"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface swarm.defobj.<A HREF="../../swarm/defobj/Drop.html">Drop</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../swarm/defobj/Drop.html#drop()">drop</A></CODE></TD></TR></TABLE> <A NAME="methods_inherited_from_class_swarm.collections.Offsets"><!-- --></A>⌨️ 快捷键说明
