java.lang.Enum<Token>

us.bpsm.edn.parser.Token

All Implemented Interfaces:

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

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

The members of this enum are a subset of the values that may be returned by Scanner.nextToken(Parseable).

Enum Constant Summary

Enum Constants

Enum Constant and Description
BEGIN_LIST A '(', which begins a list
BEGIN_MAP A '{', which begins a map
BEGIN_SET A '#{', which begins a set
BEGIN_VECTOR A '[', which begins a vector
DISCARD A '#_', which instructs the parser to ignore the next value parsed from the input.
END_LIST A ')', which ends a list.
END_MAP_OR_SET A '}', which ends a set or map
END_OF_INPUT Signals the end of input.
END_VECTOR A ']', which ends a vector
NIL A 'nil', which a parser should interpret as a Java null.

Method Detail

values

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

Returns:

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

valueOf

public static Token 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
