public static enum JsonFactory.Feature extends Enum<JsonFactory.Feature>
JsonFactory
.Enum Constant and Description |
---|
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 ). |
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.
|
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. |

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

valueOf(String name)
Returns the enum constant of this type with the specified name.
|
static JsonFactory.Feature[] |
values()
Returns an array containing the constants of this enum type, in
the order they are declared.

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.

).
This setting is enabled by default.
public static final JsonFactory.Feature FAIL_ON_SYMBOL_HASH_OVERFLOW
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.
