this generator (using |
| public boolean | canWriteBinaryNatively()

and need to return |
| public JsonStreamContext | getOutputContext()
Overrides com. Note type was co-variant until Jackson 2.7; reverted back to base type in 2.8 to allow for overriding by subtypes that use custom context type. |

as target for generated output; this is usually either

| public AvroGenerator | setPrettyPrinter(PrettyPrinter

| public StreamWriteConstraints | streamWriteConstraints()
Overrides com. Get the constraints to apply when performing streaming writes. |
| public AvroGenerator | useDefaultPrettyPrinter()
Overrides com. Not sure what to do here; could reset indentation to some value maybe? |
| public Version | version()
Overrides com. Implements com. Implemented with standard version number detection algorithm, typically using a simple generated class, with information extracted from Maven project file during build. |
| public void | writeBinary(Base64Variant
Base64 variant to use: defines details such as
whether padding is used (and if so, using which character);
what is the maximum line length before adding linefeed,
and also the underlying alphabet to use. b64variant, byte[] Buffer that contains binary data to write data, int Offset in offset, int data of the first byte of data to writeLength of data to write len)Implements abstract com. Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). |

Boolean value to write state)Implements abstract com. Method for outputting literal JSON boolean value (one of Strings 'true' and 'false'). |
| public void | writeEmbeddedObject(Object
Native format-specific value to write object)Overrides com. Method that can be called on backends that support passing opaque native values that some data formats support; not used with JSON backend, more common with binary formats. |
| public final void | writeEndArray()
Implements abstract com. Method for writing closing marker of a JSON Array value (character ']'; plus possible white space decoration if pretty-printing is enabled). |
