Method Details

values

public static TokenType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static TokenType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

needsParens

public boolean needsParens(TokenType other,
 boolean isLeft)

Determines if the token has greater precedence than other.

Parameters:

other - Compare token.

isLeft - Is to the left of the other.

Returns:

true if greater precedence.

isOperator

public boolean isOperator(boolean in)

Determines if the type is a valid operator.

Parameters:

in - false if IN operator should be ignored.

Returns:

true if valid operator.

getLength

public int getLength()

getName

public String getName()

getNameTS

public com.oracle.truffle.api.strings.TruffleString getNameTS()

getNameOrType

public String getNameOrType()

getNext

getKind

public TokenKind getKind()

getPrecedence

public int getPrecedence()

isLeftAssociative

public boolean isLeftAssociative()

getECMAScriptVersion

public int getECMAScriptVersion()

toString
