Class VariableBuilder

java.lang.Object

com.singularsys.extensions.mathml.builder.VariableBuilder

All Implemented Interfaces:

MathMLFragmentBuilder

public class VariableBuilder
extends Object
implements MathMLFragmentBuilder

Builder for jep variables, most variables are represented as <ci>x</ci>. Some jep constant variable (pi,e,i,true,false) have corresponding tags <pi/> etc. in MathML 2.0 these can de defined using putConstant, in MathML 1.0 these were represented as <cn> elements containing named entities like &pi;. There is buggy support for this.
