`SmileGenerator`	`disable(SmileGenerator.Feature f)`
`SmileGenerator`	`enable(SmileGenerator.Feature f)`
`void`	`flush()` Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.
`Object`	`getOutputTarget()` Method that can be used to get access to object that is used as target for generated output; this is usually either `OutputStream` or `Writer`, depending on what generator was constructed with.
`boolean`	`isEnabled(SmileGenerator.Feature f)`
`protected long`	`outputOffset()` Method for accessing offset of the next byte within the whole output stream that this generator has produced.
`JsonGenerator`	`setPrettyPrinter(PrettyPrinter pp)` No way (or need) to indent anything, so let's block any attempts.

`void`	`writeRaw(String text, int offset, int len)` Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).
`void`	`writeRawUTF8String(byte[] text, int offset, int len)` Method similar to `JsonGenerator.writeString(String)` but that takes as its input a UTF-8 encoded String that is to be output as-is, without additional escaping (type of which depends on data format; backslashes for JSON).
`void`	`writeRawValue(char[] text, int offset, int len)`
`void`	`writeRawValue(String text)` Method that will force generator to copy input text verbatim without any modifications, but assuming it must constitute a single legal JSON value (number, string, boolean, null, Array or List).

`void`	`writeString(char[] text, int offset, int len)` Method for outputting a String value.
`void`	`writeString(SerializableString sstr)` Method similar to `JsonGenerator.writeString(String)`, but that takes `SerializableString` which can make this potentially more efficient to call as generator may be able to reuse quoted and/or encoded representation.
`void`	`writeString(String text)` Method for outputting a String value.
`void`	`writeStringField(String fieldName, String value)` Convenience method for outputting a field entry ("member") that has a String value.
`void`	`writeUTF8String(byte[] text, int offset, int len)` Method similar to `JsonGenerator.writeString(String)` but that takes as its input a UTF-8 encoded String which has not been escaped using whatever escaping scheme data format requires (for JSON that is backslash-escaping for control characters and double-quotes; for other formats something else).

    Method that can be called to explicitly write Smile document header. Note that usually you do not need to call this for first document to output, but rather only if you intend to write multiple root-level documents with same generator (and even in that case this is optional thing to do). As a result usually only SmileFactory calls this method.

    从类复制的说明: JsonGenerator
    
    Method that can be used to get access to object that is used as target for generated output; this is usually either OutputStream or Writer, 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.

    Method that will output given chunk of binary data as base64 encoded, as a complete String value (surrounded by double quotes). This method defaults
    Note: 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.
    
    指定者:

    b64variant - 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.

    Note: because of lack of type safety, some generator implementations may not be able to implement this method. For example, if a binary json format is used, it may require type information for encoding; similarly for generator-wrappers around Java objects or Json nodes. If implementation does not implement this method, it needs to throw UnsupportedOperationException.
