Enum Constant Detail

• QUOTE_FIELD_NAMES

  public static final JsonWriteFeature QUOTE_FIELD_NAMES

  Feature that determines whether JSON Object field names are quoted using double-quotes, as specified by JSON specification or not. Ability to disable quoting was added to support use cases where they are not usually expected, which most commonly occurs when used straight from Javascript.

  Feature is enabled by default (since it is required by JSON specification).

• WRITE_NAN_AS_STRINGS

  public static final JsonWriteFeature WRITE_NAN_AS_STRINGS

  Feature that determines whether "NaN" ("not a number", that is, not real number) float/double values are output as JSON strings. The values checked are Double.Nan, Double.POSITIVE_INFINITY and Double.NEGATIVE_INIFINTY (and associated Float values). If feature is disabled, these numbers are still output using associated literal values, resulting in non-conforming output.

  Feature is enabled by default.

• ESCAPE_NON_ASCII

  public static final JsonWriteFeature ESCAPE_NON_ASCII

  Feature that specifies that all characters beyond 7-bit ASCII range (i.e. code points of 128 and above) need to be output using format-specific escapes (for JSON, backslash escapes), if format uses escaping mechanisms (which is generally true for textual formats but not for binary formats).

  Note that this setting may not necessarily make sense for all data formats (for example, binary formats typically do not use any escaping mechanisms; and some textual formats do not have general-purpose escaping); if so, settings is simply ignored. Put another way, effects of this feature are data-format specific.

  Feature is disabled by default.

Method Detail

• values

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

  Returns:

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

• valueOf

  public static JsonWriteFeature 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()

  Description copied from interface: FormatFeature
  Accessor for checking whether this feature is enabled by default.

  Specified by:

  enabledByDefault in interface FormatFeature

• getMask

  public int getMask()

  Description copied from interface: FormatFeature
  Returns bit mask for this feature instance; must be a single bit, that is of form (1 << N)

  Specified by:

  getMask in interface FormatFeature

• enabledIn

  public boolean enabledIn(int flags)

  Description copied from interface: FormatFeature
  Convenience method for checking whether feature is enabled in given bitmask

  Specified by:

  enabledIn in interface FormatFeature

• mappedFeature

  public JsonGenerator.Feature mappedFeature()
