<p>The RelinkingTool allows the user to reconnect an existing <a href="Link.html">Link</a>
if the <a href="Link.html#relinkableTo">Link.relinkableTo</a> and/or <a href="Link.html#relinkableFrom">Link.relinkableFrom</a> properties are true.</p>
<p class="boxread">
For a general discussion of validation, see <a href="../../intro/validation.html">Introduction to Validation</a>.
<p>By default an instance of this tool is installed as a mouse-down tool in the
<a href="Diagram.html#toolManager">Diagram.toolManager</a> as the <a href="ToolManager.html#relinkingTool">ToolManager.relinkingTool</a>.</p>
<p>This tool makes use of two <a href="Adornment.html">Adornment</a>s,
each including a relink handle (potentially one for each end of the link),
shown when a link is selected.</p>
<p>This tool conducts a transaction while the tool is active.
A successful relinking will result in a "LinkRelinked" <a href="DiagramEvent.html">DiagramEvent</a> and a "Relinking" transaction.</p>
<p>If you want to programmatically start a new user's relinking of a <a href="Link.html">Link</a>,
you can set the <a href="RelinkingTool.html#handle">handle</a> property to the specific "RelinkFrom" or "RelinkTo" handle and
then start and activate the tool.</p>

saving the result in <a href="RelinkingTool.html#handle">handle</a>.</p>
<p>Normally when this method is called the value of <a href="LinkingBaseTool.html#originalLink">LinkingBaseTool.originalLink</a> and <a href="RelinkingTool.html#handle">handle</a> will be null,
resulting in a call to <a href="Tool.html#findToolHandleAt">Tool.findToolHandleAt</a> to find a "RelinkFrom" or "RelinkTo" tool handle,
which is then remembered as the value of <a href="RelinkingTool.html#handle">handle</a>.
If when this method is called the value of <a href="RelinkingTool.html#handle">handle</a> is already set,
then there is no need to call <a href="Tool.html#findToolHandleAt">Tool.findToolHandleAt</a>,
because the programmer has already set up which relinking handle they want the user to be relinking.
Finding a handle is not necessary if <a href="LinkingBaseTool.html#originalLink">LinkingBaseTool.originalLink</a> and
<a href="LinkingBaseTool.html#isForwards">isForwards</a> have been set before calling this method.</p>
<p>This starts a transaction, captures the mouse, and sets the cursor.</p>
<p>If <a href="LinkingBaseTool.html#originalLink">LinkingBaseTool.originalLink</a> or <a href="RelinkingTool.html#handle">handle</a> was not set beforehand,
the value of <a href="LinkingBaseTool.html#isForwards">isForwards</a> is set depending on the category of the relink handle found.
The <a href="LinkingBaseTool.html#originalLink">LinkingBaseTool.originalLink</a> property and various
"Original..." port and node properties are set too.
The temporary nodes and temporary link are also initialized.</p>
<p>This method may be overridden, but we recommend that you call this base method.</p>

<p>A mouse-up ends the relinking operation; if there is a valid <a href="LinkingBaseTool.html#targetPort">targetPort</a> nearby,
this modifies the old link to connect with the target port.</p>
<p>A successful relinking calls <a href="RelinkingTool.html#reconnectLink">reconnectLink</a> to actually change the link.
The "LinkRelinked" <a href="DiagramEvent.html">DiagramEvent</a> is raised with the link as the <a href="DiagramEvent.html#subject">DiagramEvent.subject</a>
and with the now-disconnected original port as the <a href="DiagramEvent.html#parameter">DiagramEvent.parameter</a>.
If the link was not reconnected, this calls <a href="RelinkingTool.html#doNoRelink">doNoRelink</a>.
In any case this stops the tool.</p>
<p>A failure to find a valid target port results in no changes and no DiagramEvent.</p>
<p>This method may be overridden, but we recommend that you call this base method.
You might find it easier to override <a href="RelinkingTool.html#reconnectLink">reconnectLink</a>.
It is actually most common to implement a "LinkRelinked" <a href="DiagramEvent.html">DiagramEvent</a> listener on the <a href="Diagram.html">Diagram</a>.</p>
