Class MathMLExpression.MathMLHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.jscience.ml.sbml.math.MathMLExpression.MathMLHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

Enclosing class:

MathMLExpression

protected class MathMLExpression.MathMLHandler
extends org.xml.sax.helpers.DefaultHandler

Receives events from SAX and builds a parse tree. The parse tree exactly matches the MathML file. For every element there is a node. Each node has a child for each element it encloses. The MathML <apply><times/><cn>5<cn><cn>2 <cn></apply> has a root node with "apply" and 3 children with "times", "5", and "2" (the order is preserved).
