EquationNode.AddChild

AddChild(EquationNodeType)

Insert a node of the specified type at the end of the child node list of the current node.

public EquationNode AddChild(EquationNodeType equationType)
ParameterTypeDescription
equationTypeEquationNodeTypeTypes of Equation Nodes

Return Value

If the specified type exists, the corresponding node is returned, and if the type does not exist, a node of unknown type is returned.
