<P>The <A HREF="../../src/lib/rrdMultiFile.js">rrdMultiFile
Javascript module</A> implements a set of classes that can be used
to combine several <A HREF="rrdFile_js.html#RRDFile">RRDFile</A>
objects into one. They all implement the same interface as
<A HREF="rrdFile_js.html#RRDFile">RRDFile</A>.</P>

<H2 CLASS="heading-2-western">Overview</H2>
<P>The main class in this module is <A HREF="#RRDFileSum">RRDFileSum</A>.
Given a list of similar <A HREF="rrdFile_js.html#RRDFile">RRDFile</A>
objects, it creates a new object that behaves like a <A HREF="rrdFile_js.html#RRDFile">RRDFile</A>
object where the input shave been summed up.</P>
<H2 CLASS="heading-2-western"><A NAME="RRDFileSum"></A>Class RRDFileSum</H2>
<P>This is the main class of the package. It is also the only class
the user ever needs to explicitly instantiate.</P>
<P>The RRDFileSum constructor has two argument:</P>
<UL>
<LI><P>A list of similar <A HREF="rrdFile_js.html#RRDFile">RRDFile</A>
objects.<BR>They must all have the same DSes and the same RRAs.</P>
<LI><P>A boolean (default=true) – This value defines how to treat
undefined values. If true, they are counted as zeros and the sum
will always succeed. If it is false, any undefined value in one of
the input objects will result in the sum being marked as undefined.</P>
</UL>
<P>This class implements the same interface as <A HREF="rrdFile_js.html#RRDFile">RRDFile</A>.</P>
<H2 CLASS="heading-2-western"><A NAME="RRDRRASum"></A>Class RRDRRASum</H2>
<P>This class implements the same interface as <A HREF="rrdFile_js.html#RRDRRA">RRDRRA.</A></P>
