Enum TokenType

java.lang.Object
  java.lang.Enum<TokenType>
      org.millscript.millscript.syntax.TokenType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TokenType>

public enum TokenType
extends java.lang.Enum<TokenType>

This enumeration describes the valid types of token that can be generated by the tokenizer.

Enum Constant Summary

EOF
Used to indicate we've reached the end of file.

INTEGER
Used to indicate the current token is an integer.

NAME
Used to indicate the current token is a name.

NEED_NEW
Used to indicate when we need a new token.

STRING
Used to indicate the current token is a string.

TRADITIONAL_REGEX
Used to indicate the current token is a traditional regular expression token.

Method Summary

static TokenType	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static TokenType[]	values() Returns an array containing the constants of this enum type, in the order they're declared.

Enum Constant Detail

EOF

public static final TokenType EOF

Used to indicate we've reached the end of file. This is returned when the end of file is reached, but not if it is reached part way through reading a token.

INTEGER

public static final TokenType INTEGER

Used to indicate the current token is an integer.

NAME

public static final TokenType NAME

Used to indicate the current token is a name.

NEED_NEW

public static final TokenType NEED_NEW

Used to indicate when we need a new token. This is used when the current token is dropped.

STRING

public static final TokenType STRING

Used to indicate the current token is a string.

TRADITIONAL_REGEX

public static final TokenType TRADITIONAL_REGEX

Used to indicate the current token is a traditional regular expression token.

Method Detail

values

public static final TokenType[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(TokenType c : TokenType.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static TokenType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
