Method Detail

close

public void close()
           throws IOException
Description copied from class: JsonGenerator
Method called to close this generator, so that no more content can be written.

Whether the underlying target (stream, writer) gets closed depends on whether this generator either manages the target (i.e. is the only one with access to the target -- case if caller passes a reference to the resource such as File, but not stream); or has feature JsonGenerator.Feature.AUTO_CLOSE_TARGET enabled. If either of above is true, the target is also closed. Otherwise (not managing, feature not enabled), target is not closed.

Specified by:
close in interface Closeable
Specified by:
close in class JsonGenerator
Throws:
IOException

copyCurrentEvent

public void copyCurrentEvent(JsonParser jp)
                      throws IOException,
                             JsonProcessingException
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 class JsonGenerator
Throws:
IOException
JsonProcessingException

copyCurrentStructure

public void copyCurrentStructure(JsonParser jp)
                          throws IOException,
                                 JsonProcessingException
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:

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.

Specified by:
copyCurrentStructure in class JsonGenerator
Throws:
IOException
JsonProcessingException

disable

public JsonGenerator disable(JsonGenerator.Feature f)

flush

public void flush()
           throws IOException
Description copied from class: JsonGenerator
Method called to flush any buffered content to the underlying target (output stream, writer), and to flush the target itself as well.

Specified by:
flush in class JsonGenerator
Throws:
IOException

getCodec

public ObjectCodec getCodec()
Description copied from class: JsonGenerator
Method for accessing the object used for writing Java object as Json content (using method JsonGenerator.writeObject(java.lang.Object)).

Specified by:
getCodec in class JsonGenerator

getOutputContext

public JsonStreamContext getOutputContext()
Specified by:
getOutputContext in class JsonGenerator
Returns:
Context object that can give information about logical position within generated json content.

isClosed

public boolean isClosed()
Description copied from class: JsonGenerator
Method that can be called to determine whether this generator is closed or not. If it is closed, no more output can be done.

Specified by:
isClosed in class JsonGenerator

isEnabled

public boolean isEnabled(JsonGenerator.Feature f)
Description copied from class: JsonGenerator
Method for checking whether given feature is enabled. Check JsonGenerator.Feature for list of available features.

Specified by:
isEnabled in class JsonGenerator

setCodec

public JsonGenerator setCodec(ObjectCodec oc)
Description copied from class: JsonGenerator
Method that can be called to set or reset the object to use for writing Java objects as JsonContent (using method JsonGenerator.writeObject(java.lang.Object)).

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 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.

Specified by:
writeBinary in class JsonGenerator
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
JsonGenerationException

writeBoolean

                         JsonGenerationException
Description copied from class: JsonGenerator
Method for outputting literal Json boolean value (one of Strings 'true' and 'false'). Can be called in any context where a value is expected (Array value, Object field value, root-level value). Additional white space may be added around the value if pretty-printing is enabled.

Specified by:
writeBoolean in class JsonGenerator
Throws:
IOException
JsonGenerationException

writeEndArray

public void writeEndArray()
                   throws IOException,
                          JsonGenerationException
Description copied from class: JsonGenerator
Method for writing closing marker of a JSON Array value (character ']'; plus possible white space decoration if pretty-printing is enabled).

Marker can be written if the innermost structured type is Array.

Specified by:
writeEndArray in class JsonGenerator
Throws:
IOException
JsonGenerationException

writeEndObject

public void writeEndObject()
                    throws IOException,
                           JsonGenerationException
Description copied from class: JsonGenerator
Method for writing closing marker of a JSON Object value (character '}'; plus possible white space decoration if pretty-printing is enabled).

Marker can be written if the innermost structured type is Object, and the last written event was either a complete value, or START-OBJECT marker (see JSON specification for more details).

Specified by:
writeEndObject in class JsonGenerator
Throws:
IOException
JsonGenerationException

writeFieldName

public 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.

Specified by:
writeFieldName in class JsonGenerator
Throws:
IOException
JsonGenerationException

writeFieldName

public void writeFieldName(SerializedString name)
                    throws IOException,
                           JsonGenerationException
Description copied from class: JsonGenerator
Method similar to JsonGenerator.writeFieldName(String), main difference being that it may perform better as some of processing (such as quoting of certain characters, or encoding into external encoding if supported by generator) can be done just once and reused for later calls.

Default implementation simple uses unprocessed name container in serialized String; implementations are strongly encouraged to make use of more efficient methods argument object has.

                        JsonGenerationException,
                        UnsupportedOperationException
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, regular JsonGenerator.writeString(java.lang.String) method can not be used; nor JsonGenerator.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 UnsupportedOperationException.

                 throws IOException,
                        JsonProcessingException
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.

Method for outputting a String value. Depending on context this means either array element, (object) field value or a stand alone String; but in all cases, String will be surrounded in double quotes, and contents will be properly escaped as required by JSON specification.

writeString

public void writeString(SerializableString text)
                 throws IOException,
                        JsonGenerationException
Description copied from class: JsonGenerator
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.

Default implementation just calls JsonGenerator.writeString(String); sub-classes should override it with more efficient implementation if possible.

Throws:
IOException
JsonGenerationException

writeRawUTF8String

public void writeRawUTF8String(byte[] text,
                               int offset,
                               int length)
                        throws IOException,
                               JsonGenerationException
Description copied from class: JsonGenerator
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). 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 Writer using this method would require UTF-8 decoding. If so, implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

                     throws IOException,
                            JsonGenerationException
Description copied from class: JsonGenerator
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). 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 Writer using this method would require UTF-8 decoding. In this case generator implementation may instead choose to throw a UnsupportedOperationException due to ineffectiveness of having to decode input.

writeTree

public void writeTree(JsonNode rootNode)
               throws IOException,
                      JsonProcessingException
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 call JsonGenerator.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.

writeTree in class JsonGenerator
Throws:
IOException
