Class Terminal

java.lang.Object

org.oristool.lello.parse.Terminal

public class Terminal
extends Object

Represents a terminal symbol. A terminal symbol consists of a kind, which influences the behavior (precedence, associativity, etc...) of the parser when it encounters the symbol, and a string called token that specifies the exact form in which the token was written within the input file; the token influences evaluation and AST manipulation. In order to allow accurate error reporting every token stores the row and column number where it was located in the input file.
