Class EquationComponentNode

EquationComponentNode class

This class specifies the components of an equation or mathematical expression. Different types of components combined into different equations. For example, a fraction consists of two parts, a numerator component and a denominator component. For more component types, please refer to ‘EquationNodeType’.
