Properties

binaryOperatorOfCompoundAssignment TokenType?
The binary operator that is invoked by this compound assignment operator, or null otherwise.
finalinherited
hashCode int
The hash code for this object.
no setterinherited
isAdditiveOperator bool
Return true if this type of token represents an additive operator.
no setterinherited
isAssignmentOperator bool
Return true if this type of token represents an assignment operator.
no setterinherited
isAssociativeOperator bool
Return true if this type of token represents an associative operator. An associative operator is an operator for which the following equality is true: (a * b) * c == a * (b * c). In other words, if the result of applying the operator to multiple operands does not depend on the order in which those applications occur.
no setterinherited
isBinaryOperator bool
true if this token type represents a binary operator.
finalinherited
isBuiltIn bool
A flag indicating whether the keyword is a "built-in" identifier.
no setteroverride
isBuiltInOrPseudo bool
no setter
isEqualityOperator bool
Return true if this type of token represents an equality operator.
no setterinherited
isIncrementOperator bool
Return true if this type of token represents an increment operator.
no setterinherited
isKeyword bool
Return true if this type of token is a keyword.
no setterinherited
isModifier bool
true if this token type represents a modifier such as abstract or const.
finalinherited
isMultiplicativeOperator bool
Return true if this type of token represents a multiplicative operator.
no setterinherited
isOperator bool
true if this token type represents an operator.
finalinherited
isPseudo bool
A flag indicating whether the keyword can be used as an identifier in some situations.
no setteroverride
isRelationalOperator bool
Return true if this type of token represents a relational operator.
no setterinherited
isReservedWord bool
A flag indicating whether the keyword is a "reserved word".
no setteroverride
isSelectorOperator bool
Return true if this type of token represents a selector operator (starting token of a selector).
no setterinherited
isShiftOperator bool
Return true if this type of token represents a shift operator.
no setterinherited
isTopLevelKeyword bool
true if this token type represents a keyword starting a top level declaration such as class, enum, import, etc.
finalinherited
isUnaryPostfixOperator bool
Return true if this type of token represents a unary postfix operator.
no setterinherited
isUnaryPrefixOperator bool
Return true if this type of token represents a unary prefix operator.
no setterinherited
isUserDefinableOperator bool
true if this token type represents an operator that can be defined by users.

final
kind int
finalinherited
lexeme String
The lexeme that defines this type of token, or null if there is more than one possible lexeme for this type of token.
finalinherited
name String
The name of the keyword type.
no setteroverride
precedence int
The precedence of this type of token, or 0 if the token does not represent an operator.
finalinherited
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
