open override var line: Int

is the line at which the statement/code component begins in the program text file

var op: BinaryExpression.BinaryOperator

represents the operator

open override var parent: IsParent?

open override fun replaceChild(initial: AstObject, replacement: AstObject)

Is replacing a certain child of the class with another object of the same type If the two parameters don't have the same type, no block will be replaced. If the type of initial doesn't match any of the current node children, no child will be replaced

setParentForChildren
