STRING

Original pattern throws the StackOverflowError for long strings with backslashes. So it is replaced by a 2-step approach inspired from json2.js sources: https://github.com/douglascrockford/JSON-js/blob/master/json2.js#L462 See JsonTokenTypeTest#testMatchingLongStringWithBackslashes() for details. RMH changed this to use a Function instead of a closure.

Method Detail

values

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

Returns:

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

valueOf

public static JsonTokenType 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

NullPointerException - if the argument is null

matching

public boolean matching(String input)

Tells if an input string matches a token.

Parameters:

input - the input string to match

Returns:

a Matching enum value: YES if this is an exact match, POSSIBLE if more characters could turn the input string into a valid token, or NO if the string cannot possibly match the pattern even with more characters to read.

startingWith

public static JsonTokenType startingWith(char c)

Find which JSON value might be starting with a given character

Parameters:

c - the character

Returns:

the possible token type found

getLabel

public String getLabel()

getValidator

public Object getValidator()
