Enum Constant Detail

• INTERN_FIELD_NAMES

  public static final JsonFactory.Feature INTERN_FIELD_NAMES

  Feature that determines whether JSON object field names are to be canonicalized using String.intern() or not: if enabled, all field names will be intern()ed (and caller can count on this being true for all such names); if disabled, no intern()ing is done. There may still be basic canonicalization (that is, same String will be used to represent all identical object property names for a single document).

  Note: this setting only has effect if CANONICALIZE_FIELD_NAMES is true -- otherwise no canonicalization of any sort is done.

  This setting is enabled by default.

• CANONICALIZE_FIELD_NAMES

  public static final JsonFactory.Feature CANONICALIZE_FIELD_NAMES

  Feature that determines whether JSON object field names are to be canonicalized (details of how canonicalization is done then further specified by INTERN_FIELD_NAMES).

  This setting is enabled by default.

• FAIL_ON_SYMBOL_HASH_OVERFLOW

  public static final JsonFactory.Feature FAIL_ON_SYMBOL_HASH_OVERFLOW

  Feature that determines what happens if we encounter a case in symbol handling where number of hash collisions exceeds a safety threshold -- which almost certainly means a denial-of-service attack via generated duplicate hash codes. If feature is enabled, an IllegalStateException is thrown to indicate the suspected denial-of-service attack; if disabled, processing continues but canonicalization (and thereby intern()ing) is disabled) as protective measure.

  This setting is enabled by default.

  Since:

  2.4

• USE_THREAD_LOCAL_FOR_BUFFER_RECYCLING

  public static final JsonFactory.Feature USE_THREAD_LOCAL_FOR_BUFFER_RECYCLING

  Feature that determines whether we will use BufferRecycler with ThreadLocal and SoftReference, for efficient reuse of underlying input/output buffers. This usually makes sense on normal J2SE/J2EE server-side processing; but may not make sense on platforms where SoftReference handling is broken (like Android), or if there are retention issues due to ThreadLocal (see Issue #189 for a possible case)

  Since:

  2.6

Method Detail

• values

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

  Returns:

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

• valueOf

  public static JsonFactory.Feature 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

• collectDefaults

  public static int collectDefaults()

  Method that calculates bit set (flags) of all features that are enabled by default.

• enabledByDefault

  public boolean enabledByDefault()

• enabledIn

  public boolean enabledIn(int flags)

• getMask

  public int getMask()
