_maximumNonEscapedChar
Value between 128 (0x80) and 65535 (0xFFFF) that indicates highest
Unicode code point that will not need escaping; or 0 to indicate
that all characters can be represented without escaping.

Currently active set of output escape code definitions (whether
and how to escape or not) for 7-bit ASCII range (first 128
character codes).

different from "general textual" defaults

sOutputEscapes
This is the default set of escape codes, over 7-bit ASCII range
(first 128 character codes), used for single-byte UTF-8 characters.

JsonGenerator |
disable(JsonGenerator.Feature f)
Method for disabling specified feature
(check
JsonGenerator.Feature for list of features) |
JsonGenerator |
enable(JsonGenerator.Feature f)
Method for enabling specified generator feature:
check
JsonGenerator.Feature for list of available features. |
CharacterEscapes |
getCharacterEscapes()
Method for accessing custom escapes factory uses for
JsonGenerator s
it creates. |
int |
getHighestEscapedChar()
Accessor method for testing what is the highest unescaped character
configured for this generator.
|
JacksonFeatureSet<StreamWriteCapability> |
getWriteCapabilities()
Accessor for getting metadata on capabilities of this generator, based on
underlying data format being read (directly or indirectly).
|
JsonGenerator |
setCharacterEscapes(CharacterEscapes esc)
Method for defining custom escapes factory uses for
JsonGenerator s
it creates. |
JsonGenerator |
setHighestNonEscapedChar(int charCode)
Method that can be called to request that generator escapes
all character codes above specified code point (if positive value);
or, to not escape any characters except for ones that must be
escaped for the data format (if -1).
|
JsonGenerator |
setRootValueSeparator(SerializableString sep)
Method that allows overriding String used for separating root-level
JSON values (default is single space character)
|
Version |
version()
Implemented with standard version number detection algorithm, typically using
a simple generated class, with information extracted from Maven project file
during build.

JsonGenerator
Note that generators are NOT required to support setting of value higher than 127, because there are other ways to affect quoting (or lack thereof) of character codes between 0 and 127. Not all generators support concept of escaping, either; if so, calling this method will have no effect.
Default implementation does nothing; sub-classes need to redefine it according to rules of supported data format.
