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. |

protected SerializableString |
_rootValueSeparator
Separator to use, if any, between root-level values. |

CharacterEscapes |
getCharacterEscapes()
Method for accessing custom escapes factory uses for JsonGenerators
it creates. |

getHighestEscapedChar()
Accessor method for testing what is the highest unescaped character configured for this generator. |
JsonGenerator |
setCharacterEscapes(CharacterEscapes esc)
Method for defining custom escapes factory uses for JsonGenerators
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 detection that tries to find "VERSION.txt" in same package as the implementation class. |

writeStringField(String fieldName,

Convenience method for outputting a field entry ("member") that has a String value. |

public JsonGenerator setHighestNonEscapedChar(int charCode)
JsonGeneratorNote 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.
setHighestNonEscapedChar in class JsonGeneratorcharCode - Either -1 to indicate that no additional escaping
is to be done; or highest code point not to escape (meaning higher
ones will be), if positive value.public int getHighestEscapedChar()
