All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler

public class IsotopeHandler
extends DefaultHandler

Reads an isotope list in CML2 format. An example definition is:

<isotopeList id="H">
  <isotope id="H1" isotopeNumber="1" elementTyp="H">
    <abundance dictRef="cdk:relativeAbundance">100.0</abundance>
    <scalar dictRef="cdk:exactMass">1.00782504</scalar>
    <scalar dictRef="cdk:atomicNumber">1</scalar>
  </isotope>
  <isotope id="H2" isotopeNumber="2" elementTyp="H">
    <abundance dictRef="cdk:relativeAbundance">0.015</abundance>
    <scalar dictRef="cdk:exactMass">2.01410179</scalar>
    <scalar dictRef="cdk:atomicNumber">1</scalar>
  </isotope>
</isotopeList>
