An adapter for using the streaming capabilities of the Jackson Open Source library. Enables low-level efficient reading and writing of JSON documents.
Always call
close()
when finished with this handle to release
the resources.

Modifier and Type | Method | Description |
---|---|---|
void |
close() |
Always call close() when finished with this
handle -- it closes the underlying InputStream.
|
com.fasterxml.jackson.core.JsonParser |
get() |
JsonParser allows streaming access to content as
it arrives.
|
java.lang.Class<com.fasterxml.jackson.core.JsonParser> |
getContentClass() |
Returns the class of the handled content, which
may be a base class of the actual class of a content object.
|
com.fasterxml.jackson.databind.ObjectMapper |
getMapper() |
Provides access to the ObjectMapper used
internally so you can configure it to fit your JSON.
|
protected boolean |
hasContent() |
|
static ContentHandleFactory |
newFactory() |
Creates a factory to create a
JacksonParserHandle instance for a JsonParser.
|
protected void |
receiveContent(java.io.InputStream content) |
|
void |
set(com.fasterxml.jackson.core.JsonParser parser) |
Available for the edge case that content from a
JsonParser must be written.
|
void |
setMapper(com.fasterxml.jackson.databind.ObjectMapper mapper) |
Enables clients to specify their own
ObjectMapper instance, including databinding mappers for formats
other than JSON.
|
JacksonParserHandle |
with(com.fasterxml.jackson.core.JsonParser parser) |
Assigns the JsonParser and returns the
handle.
|
JacksonParserHandle |
withFormat(Format format) |
Specifies the format of the content and returns
the handle as a fluent convenience.
|
void |
write(java.io.OutputStream out) |
Implements a callback to write content to the
provided output stream for sending to the database server.

Use at your own risk! Note that you most likely want to set to
false the two options we demonstrate above
(JsonGenerator.Feature.AUTO_CLOSE_TARGET and
JsonParser.Feature.AUTO_CLOSE_SOURCE) as we do so your mapper will
not close streams which we may need to reuse if we have to resend a
network request.setMapper
