setHighestNonEscapedChar
public JsonGenerator setHighestNonEscapedChar(int charCode)
Description copied from class:JsonGenerator
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). To force escaping of all non-ASCII characters, for example, this method would be called with value of 127.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.
- Overrides:
setHighestNonEscapedChar
in classJsonGenerator
- Parameters:
charCode
- 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.
-
getHighestEscapedChar
public int getHighestEscapedChar()
Description copied from class:JsonGenerator
Accessor method for testing what is the highest unescaped character configured for this generator. This may be either positive value (when escaping configuration has been set and is in effect), or 0 to indicate that no additional escaping is in effect. Some generators may not support additional escaping: for example, generators for binary formats that do not use escaping should simply return 0.- Overrides:
getHighestEscapedChar
in classJsonGenerator
- Returns:
- Currently active limitation for highest non-escaped character, if defined; or -1 to indicate no additional escaping is performed.
-

- Since:

-
getOutputTarget
public Object getOutputTarget()
Description copied from class:JsonGenerator
Method that can be used to get access to object that is used as target for generated output; this is usually eitherOutputStream
orWriter
, depending on what generator was constructed with. Note that returned value may be null in some cases; including case where implementation does not want to exposed raw source to caller. In cases where output has been decorated, object returned here is the decorated version; this allows some level of interaction between users of generator and decorator object.In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.
- Overrides:
getOutputTarget
in classJsonGenerator
-
writeFieldName
public final void writeFieldName(String name) throws IOException, JsonGenerationException
Description copied from class:JsonGenerator
Method for writing a field name (JSON String surrounded by double quotes: syntactically identical to a JSON String value), possibly decorated by white space if pretty-printing is enabled.Field names can only be written in Object context (check out JSON specification for details), when field name is expected (field names alternate with values).

writeFieldName

writeBinary
public void writeBinary(Base64Variant b64variant, byte[] data, int offset, int len) throws IOException, JsonGenerationException
Description copied from class:JsonGenerator
Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaultsNote: because Json Strings can not contain unescaped linefeeds, if linefeeds are included (as per last argument), they must be escaped. This adds overhead for decoding without improving readability. Alternatively if linefeeds are not included, resulting String value may violate the requirement of base64 RFC which mandates line-length of 76 characters and use of linefeeds. However, all
JsonParser
implementations are required to accept such "long line base64"; as do typical production-level base64 decoders.- Specified by:
writeBinary
