<h1>[name]</h1>
<p class="desc">
Buffered scene graph property that allows weighted accumulation; used internally.
</p>
<h2>Constructor</h2>
<h3>[name]( [param:PropertyBinding binding], [param:String typeName], [param:Number valueSize] )</h3>
<p>
-- binding <br />
-- typeName <br />
-- valueSize <br />
</p>
<h2>Properties</h2>
<h3>[property:PropertyBinding binding]</h3>
<p>
</p>
<h3>[property:TypedArray buffer]</h3>
<p>
Buffer with size [page:PropertyMixer valueSize] * 4. <br /><br />
This has the layout: [ incoming | accu0 | accu1 | orig ]<br /><br />
Interpolators can use .buffer as their .result and the data then goes to 'incoming'.
'accu0' and 'accu1' are used frame-interleaved for the cumulative result and
are compared to detect changes. 'orig' stores the original state of the property.
</p>
<h3>[property:Number cumulativeWeight]</h3>
<p>
Default is *0*.
</p>
<h3>[property:Number valueSize]</h3>
<p>
</p>
<h3>[property:Number referenceCount]</h3>
<p>
Default is *0*.
</p>
<h3>[property:Number useCount]</h3>
<p>
Default is *0*.
</p>
<h2>Methods</h2>
<h3>[method:null accumulate]( [param:Number accuIndex], [param:Number weight] )</h3>
<p>
Accumulate data in [page:PropertyMixer.buffer buffer][accuIndex] 'incoming' region into 'accu[i]'.<br />
If weight is *0* this does nothing.
</p>
<h3>[method:null apply]( [param:Number accuIndex] )</h3>
<p>
Apply the state of [page:PropertyMixer.buffer buffer] 'accu[i]' to the binding when accus differ.
</p>
<h3>[method:null saveOriginalState]( )</h3>
<p>
Remember the state of the bound property and copy it to both accus.
</p>
<h3>[method:null restoreOriginalState]( )</h3>
<p>
Apply the state previously taken via 'saveOriginalState' to the binding.
