Feature that determines whether generator will automatically close underlying output target that is NOT owned by the generator. If disabled, calling application has to separately close the underlying OutputStream and Writer instances used to create the generator. If enabled, generator will handle closing, as long as generator itself gets closed: this happens when end-of-input is encountered, or generator is closed by a call to JsonGenerator.close. 

Feature is enabled by default.

Feature that determines what happens when the generator is closed while there are still unmatched JsonToken.START_ARRAY or JsonToken.START_OBJECT entries in output content.

Feature that specifies that calls to JsonGenerator.flush will cause matching flush() to underlying OutputStream or Writer; if disabled this will not be done. Main reason to disable this feature is to prevent flushing at generator level, if it is not possible to prevent method being called by other code (like ObjectMapper or third
party libraries).

Feature that determines whether BigDecimal entries are serialized using BigDecimal.toPlainString() to prevent values to be written using scientific notation. 
 NOTE: only affects generators that serialize BigDecimals using textual representation (textual formats but potentially some binary formats). 
 Feature is disabled by default, so default output mode is used; this generally depends on how BigDecimal has been created. /**

Feature that determines whether JsonGenerator will explicitly check that no duplicate JSON Object field names are written. If enabled, generator will check all names within context and report duplicates by throwing a JsonGenerationException; if disabled, no such checking will be done. Assumption in latter case is that caller takes care of not trying to write duplicate names. 

Note that enabling this feature will incur performance overhead
due to having to store and check additional information.

Feature that determines what to do if the underlying data format requires knowledge of all properties to output, and if no definition is found for a property that caller tries to write. If enabled, such properties will be quietly ignored; if disabled, a JsonProcessingException will be thrown to indicate the problem. Typically most textual data formats do NOT require schema information (although some do, such as CSV), whereas many binary data formats do require definitions (such as Avro, protobuf), although not all (Smile, CBOR, BSON and MessagePack do not). 

Note that support for this feature is implemented by individual data format
module, if (and only if) it makes sense for the format in question. For JSON,
for example, this feature has no effect as properties need not be pre-defined.
 Feature is disabled by default, meaning that if the underlying data format requires knowledge of all properties to output, attempts to write an unknown property will result in a JsonProcessingException /**
