A token type. Access token types via the static fields.

For example, to access the token type PLUS:

plusType = TokenType.PLUS;

The type defines the priority (precedence) of the token.

(+,-) < (*,/) < (^) < functions < (-u)

It also defines the associativity of the token. True stands for left-associative, false for right-associative.

Methods

noSuchMethod(Invocation invocation) → dynamic

noSuchMethod is invoked when users invoke a non-existent method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod in an Invocation. If noSuchMethod returns a value, that value becomes the result of the original invocation.…

toString() → String

Returns a string representation of this object.
