sequences, needed for temporary buffering.
Space efficient for different sequence lengths (especially so for smaller
ones; but not significantly less efficient for larger), highly efficient
for linear iteration and appending. Implemented as segmented/chunked
linked list of tokens; only modifications are via appends.- Since:

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). However, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.Note that some backends may choose not to support this method: for example, if underlying destination is a

public void writeUTF8String(byte[] text, int offset, int length) throws IOException, JsonGenerationException Description copied from class:JsonGenerator
Method similar toJsonGenerator.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). This means that textual JSON backends need to check if value needs JSON escaping, but otherwise can just be copied as is to output. Also, quoting that data format requires (like double-quotes for JSON) will be added around the value if and as necessary.Note that some backends may choose not to support this method: for example, if underlying destination is a

using this method would require UTF-8 decoding. In this case generator implementation may instead choose to throw aUnsupportedOperationException

writeNumber
Description copied from class:JsonGenerator
Write method that can be used for custom numeric types that can not be (easily?) converted to "standard" Java number types. Because numbers are not surrounded by double quotes, regularJsonGenerator.writeString(java.lang.String)
method can not be used; norJsonGenerator.writeRaw(java.lang.String)
because that does not properly handle value separators needed in Array or Object contexts.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

writeObject
Description copied from class:JsonGenerator
Method for writing given Java object (POJO) as Json. Exactly how the object gets written depends on object in question (ad on codec, its configuration); for most beans it will result in Json object, but for others Json array, or String or numeric value (and for nulls, Json null literal. NOTE: generator must have its object codec set to non-null value; for generators created by a mapping factory this is the case, for others not.- Specified by:

-
writeTree
Description copied from class:JsonGenerator
Method for writing given JSON tree (expressed as a tree where given JsonNode is the root) using this generator. This will generally just callJsonGenerator.writeObject(java.lang.Object)
with given node, but is added for convenience and to make code more explicit in cases where it deals specifically with trees.- Specified by:

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
in classJsonGenerator
- Parameters:
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.- Throws:
IOException

copyCurrentEvent
Description copied from class:JsonGenerator
Method for copying contents of the current event that the given parser instance points to. Note that the method will not copy any other events, such as events contained within Json Array or Object structures.Calling this method will not advance the given parser, although it may cause parser to internally process more data (if it lazy loads contents of value events, for example)
- Specified by:
copyCurrentEvent
in classJsonGenerator
- Throws:
IOException
JsonProcessingException
-
copyCurrentStructure
Description copied from class:JsonGenerator
Method for copying contents of the current event and following events that it encloses the given parser instance points to.So what constitutes enclosing? Here is the list of events that have associated enclosed events that will get copied:
JsonToken.START_OBJECT
: all events up to and including matching (closing)JsonToken.END_OBJECT
will be copiedJsonToken.START_ARRAY
all events up to and including matching (closing)JsonToken.END_ARRAY
will be copiedJsonToken.FIELD_NAME
the logical value (which can consist of a single scalar value; or a sequence of related events for structured types (Json Arrays, Objects)) will be copied along with the name itself. So essentially the whole field entry (name and value) will be copied.
After calling this method, parser will point to the last event that was copied. This will either be the event parser already pointed to (if there were no enclosed events), or the last enclosed event copied.
