Class OperatorBuilder

java.lang.Object

com.singularsys.extensions.mathml.builder.ApplyConstructor

com.singularsys.extensions.mathml.builder.OperatorBuilder

All Implemented Interfaces:

MathMLFragmentBuilder

public class OperatorBuilder
extends ApplyConstructor
implements MathMLFragmentBuilder

Builds mathml elements corresponding to operators. For most operators, like x+1 the following xml is produced

<apply><plus/><ci>x<ci/><cn>1<cn/><apply/>

Other operators have special behaviour with their own MathMLFragmentBuilder
