- All Implemented Interfaces:
java.io.Serializable,java.lang.Comparable<JsonTokenType>,java.lang.constant.Constable
public enum JsonTokenType extends java.lang.Enum<JsonTokenType>
The original slurper and lexer use this class.
This is kept around in case someone needs its exact behavior.
Enum listing all the possible JSON tokens that should be recognized by the lexer.

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.

values
Returns an array containing the constants of this enum type, in the order they are declared.- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
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 namejava.lang.NullPointerException- if the argument is null
-
matching
public boolean matching(java.lang.String input)Tells if an input string matches a token.- Parameters:
input- the input string to match- Returns:
- a
Matchingenum value:YESif this is an exact match,POSSIBLEif more characters could turn the input string into a valid token, orNOif the string cannot possibly match the pattern even with more characters to read.
-
startingWith
Find which JSON value might be starting with a given character- Parameters:
c- the character- Returns:
- the possible token type found
