## FunctionEquationNode class

This class specifies the Function-Apply equation, which consists of a function name and an argument acted upon.The types of the name and argument components are 'EquationNodeType.FunctionName' and 'EquationNodeType.Base' respectively.

```go

type FunctionEquationNode struct  {
	ptr unsafe.Pointer
}

```
