Field Detail

value

public final int value

Internal value for this token code. For tokens corresponding to a single character, the value is the ASCII code for that character. Other tokens are assigned arbitrary codes greater than 256.

Method Detail

values

public static final TokenCode[] 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(TokenCode c : TokenCode.values())
        System.out.println(c);

Returns:

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

valueOf

public static TokenCode valueOf(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:

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

toString

public String toString()

Returns a string representation for this token code. For a token corresponding to the single character c, the representation is "'c'". For others, it's the name of the token, such as BOOL or WHILE.

Overrides:

toString in class Enum<TokenCode>

Returns:

the string representation.

valueOf

public static TokenCode valueOf(int value)

Returns the TokenCode corresponding to a particular value.

Parameters:

value - the value.

Returns:

the instance corresponding to value.
