메소드 설명
Expression ( bool inGroup ) : System.Diagnostics

Constructs an expression that will be parsed as it is inside braces (in a group) so expression parsing will continue even if there is a line break that would normally terminate the expression.
Expression ( string terminatingKeyword ) : System.Diagnostics
Parse ( ParseContext context, IAstNode parent ) : bool
ToString ( ) : string

MakeNode ( ParseContext context ) : ParseErrorType

Constructs AST node from operator (root) and one or two operands. In order for the node to be successfully created stacks must contain an operator and, depending on the operator, one or two operands.
