<h3>Events</h3>
<p>This is a list of all the events in the public API. They are collected here from all individual modules.</p>

<h4id="optionsObject">Cluster options object</h4>
<p>The options object supplied to the cluster functions can contain these properties:</p>
<tr><td>startStabilizing</td><tdclass="mid">none</td><td>Fired when stabilization starts. This is also the case when you drag a node and the physics simulation restarts to stabilize again. Stabilization does not neccesarily imply 'without showing'.</td>
<td><i>Optional for all but the cluster method. </i> The cluster module loops over all nodes that are selected to be in the cluster and calls this function with their data as argument.
If this function returns true, this node will be added to the cluster. You have access to all options (including the default)
as well as any custom fields you may have added to the node to determine whether or not to include it in the cluster. Example:
<preclass="code">
{
iterations: Number // iterations so far,
total: Number // total iterations in options
var nodes = [
{id: 4, label: 'Node 4'},
{id: 5, label: 'Node 5'},
{id: 6, label: 'Node 6', cid:1},
{id: 7, label: 'Node 7', cid:1}
]
var options = {
joinCondition:function(nodeOptions) {
return nodeOptions.cid === 1;
}
}
</pre></td><td>Fired when a multiple of the <code>updateInterval</code> number of iterations is reached. This only occurs in the 'hidden' stabilization.</td></tr>
<tr><td>stabilizationIterationsDone</td><tdclass="mid">none</td><td>Fired when the 'hidden' stabilization finishes. This does not necessarily mean the network is stabilized; it could also mean that the amount of iterations defined in the options has been reached.</td>
<tr><td>stabilized</td><tdclass="mid">
network.clustering.cluster(options);
</pre></td></tr>
<tr><td>processProperties(<br> <code>Object nodeOptions</code><br>)</td><tdclass="mid">Function</td><td><i>Optional. </i> Before creating the new cluster node, this (optional) function will be called with the properties supplied by you (<code>clusterNodeProperties</code>), all contained nodes and all contained edges. You can use this to update the
properties of the cluster based on which items it contains. The function should return the properties to create the cluster node. In the example below, we ensure preservation of mass and value when forming the cluster:
<preclass="code">
{
iterations: Number // iterations it took
var options = {
processProperties: function (clusterOptions, childNodes, childEdges) {
</td><td>Fired when the network has stabilized or when the <code>stopSimulation()</code> has been called. The amount of iterations it took could be used to tweak the maximum amount of iterations needed to stabilize the network.</td>
</pre></td></tr>
<tr><td>clusterNodeProperties</td><tdclass="mid">Object</td><td><i>Optional. </i> This is an object containing the options for the cluster node. All options described in the <ahref="./nodes.html">nodes module</a> are allowed. This allows you to style your cluster node any way you want. This is also the style object that is provided in the processProperties function for fine tuning. If undefined, default node options will be used.</td></tr>
<tr><td>clusterEdgeProperties</td><tdclass="mid">Object</td><td><i>Optional. </i> This is an object containing the options for the edges connected to the cluster. All options described in the <ahref="./edges.html">edges module</a> are allowed. Using this, you can style the edges connecting to the cluster any way you want. If none are provided, the optoins from the edges that are replaced are used. If undefined, default edge options will be used.</td></tr>
