Enum Class JsonTokenType

java.lang.Object
java.lang.Enum<JsonTokenType>
groovy.json.JsonTokenType
All Implemented Interfaces:
Serializable, Comparable<JsonTokenType>, Constable
public enum JsonTokenType extends 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.
Since:
1.8.0

      Original pattern throws the StackOverflowError for long strings with backslashes. It is therefore replaced by a 2-step approach inspired by json2.js sources: https://github.com/douglascrockford/JSON-js/blob/master/json2.js#L462 See JsonTokenTypeTest#testMatchingLongStringWithBackslashes() for details.

  • Method Details

    • values

      public static JsonTokenType[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static JsonTokenType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class 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()
      Returns the human-readable description of this token type.
      Returns:
      the token label

    • getValidator

      public Object getValidator()
      Returns the validator used to recognize this token type.
      Returns:
      the token validator
