Enum Constant Summary

Enum Constants
Enum Constant and Description
`C_COMMENT` Starts with `"/*"` and ends with `"&42;/"`.
`CHARACTER_LITERAL` A Java character literal as it appears in the input, i.e. including the leading and the trailing single quote and any escape sequence.
`CXX_COMMENT` Starts with `"//"` and always ends with a line break (unless it is the last token).
`FLOATING_POINT_LITERAL` A Java floating point literal as it appears in the input, i.e. digits, decimal point and/or exponent, optionally followed by `'d'` or `'D'`.
`IDENTIFIER` A Java identifier.
`INTEGER_LITERAL` A Java integer literal as it appears in the input, i.e. a decimal, hexadecimal or octal constant, optionally followed by `'l'` or `'L'`.
`KEYWORD` One of the Java keywords (`"abstract"`, `"assert"` and so forth).
`MULTI_LINE_C_COMMENT_BEGINNING` Starts with `"/*"` and ends with a line break.
`MULTI_LINE_C_COMMENT_END` Ends with `"*/"`.
`MULTI_LINE_C_COMMENT_MIDDLE` Ends with a line break.
`OPERATOR` One of the Java "operators": >>>= <<= >>= >>> += -= *= /= &= \|= ^= %= == <= >= !
`SEPARATOR` One of the Java "separators": `( ) { } [ ] ; . ,`
`SPACE` One or more characters that are "`[ \t\n\x0B\f\r]`".
`STRING_LITERAL` A Java string literal as it appears in the input, i.e. including the leading and the trailing double quote and all escape sequences.

- Enum Constant Detail
  - SPACE
```
public static final JavaScanner.TokenType SPACE
```
    One or more characters that are "[ \t\n\x0B\f\r]".
    This token type is the only one that is not deterministic, e.g. two space could be scanned into one or into two space tokens.
  - CXX_COMMENT
```
public static final JavaScanner.TokenType CXX_COMMENT
```
    Starts with "//" and always ends with a line break (unless it is the last token).
  - C_COMMENT
```
public static final JavaScanner.TokenType C_COMMENT
```
    Starts with "/*" and ends with "&42;/".
    If the C comment spans multiple lines, the line breaks appear exactly as in the input, for example: "/**\r * @throws IOException\r\n */"
    
    Notice that a Java scanner may represent multi-line C comments either as a C_COMMENT, token, or as a sequence of
    
    MULTI_LINE_C_COMMENT_BEGINNING { MULTI_LINE_C_COMMENT_MIDDLE } MULTI_LINE_C_COMMENT_END
  - MULTI_LINE_C_COMMENT_BEGINNING
```
public static final JavaScanner.TokenType MULTI_LINE_C_COMMENT_BEGINNING
```
    Starts with "/*" and ends with a line break.
    The line break appear exactly as in the input, for example: "/**\r"
    
    Notice that a Java scanner may represent multi-line C comments either as a C_COMMENT, token, or as a sequence of
    
    MULTI_LINE_C_COMMENT_BEGINNING { MULTI_LINE_C_COMMENT_MIDDLE } MULTI_LINE_C_COMMENT_END
  - MULTI_LINE_C_COMMENT_MIDDLE
```
public static final JavaScanner.TokenType MULTI_LINE_C_COMMENT_MIDDLE
```
    Ends with a line break.
    The line break appear exactly as in the input, for example: " * @throws IOException\n"
    
    Notice that a Java scanner may represent multi-line C comments either as a C_COMMENT, token, or as a sequence of
    
    MULTI_LINE_C_COMMENT_BEGINNING { MULTI_LINE_C_COMMENT_MIDDLE } MULTI_LINE_C_COMMENT_END
  - MULTI_LINE_C_COMMENT_END
```
public static final JavaScanner.TokenType MULTI_LINE_C_COMMENT_END
```
    Ends with "*/".
    Notice that a Java scanner may represent multi-line C comments either as a C_COMMENT, token, or as a sequence of
    
    MULTI_LINE_C_COMMENT_BEGINNING { MULTI_LINE_C_COMMENT_MIDDLE } MULTI_LINE_C_COMMENT_END
  - KEYWORD
```
public static final JavaScanner.TokenType KEYWORD
```
    One of the Java keywords ("abstract", "assert" and so forth).
  - IDENTIFIER
```
public static final JavaScanner.TokenType IDENTIFIER
```
    A Java identifier.
  - SEPARATOR
```
public static final JavaScanner.TokenType SEPARATOR
```
    One of the Java "separators": ( ) { } [ ] ; . ,
  - OPERATOR
```
public static final JavaScanner.TokenType OPERATOR
```
    One of the Java "operators":
```
   >>>=
   <<= >>= >>>
   += -= *= /= &= |= ^= %=
   == <= >= != && || ++ -- << >>
   = > < ! ~ ? :
   + - * / & | ^ %
   @
 
```
  - STRING_LITERAL
```
public static final JavaScanner.TokenType STRING_LITERAL
```
    A Java string literal as it appears in the input, i.e. including the leading and the trailing double quote and all escape sequences.
  - CHARACTER_LITERAL
```
public static final JavaScanner.TokenType CHARACTER_LITERAL
```
    A Java character literal as it appears in the input, i.e. including the leading and the trailing single quote and any escape sequence.
  - INTEGER_LITERAL
```
public static final JavaScanner.TokenType INTEGER_LITERAL
```
    A Java integer literal as it appears in the input, i.e. a decimal, hexadecimal or octal constant, optionally followed by 'l' or 'L'.
  - FLOATING_POINT_LITERAL
```
public static final JavaScanner.TokenType FLOATING_POINT_LITERAL
```
    A Java floating point literal as it appears in the input, i.e. digits, decimal point and/or exponent, optionally followed by 'd' or 'D'.
- Method Detail
  - values
```
public static JavaScanner.TokenType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (JavaScanner.TokenType c : JavaScanner.TokenType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static JavaScanner.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
    
    java.lang.NullPointerException - if the argument is null
