    • values

      public static IonType[] 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 IonType 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

    • isContainer

      public static boolean isContainer(IonType t)
      Determines whether a type represents an Ion container. This includes DATAGRAM.
      Parameters:
      t - may be null.
      Returns:
      true when t is LIST, SEXP, STRUCT, or DATAGRAM.

    • isText

      public static boolean isText(IonType t)
      Determines whether a type represents an Ion text scalar, namely STRING or SYMBOL (but not CLOB).
      Parameters:
      t - may be null.
      Returns:
      true when t is STRING or SYMBOL.

    • isLob

      public static boolean isLob(IonType t)
      Determines whether a type represents an Ion LOB scalar, namely BLOB or CLOB.
      Parameters:
      t - may be null.
      Returns:
      true when t is BLOB or CLOB.
