Class JSONComposer<T>

java.lang.Object

com.fasterxml.jackson.jr.ob.comp.ComposerBase

com.fasterxml.jackson.jr.ob.comp.SequenceComposer<JSONComposer<T>>

com.fasterxml.jackson.jr.ob.JSONComposer<T>

Type Parameters:

T - Type of result being composed.

All Implemented Interfaces:

Flushable

public class JSONComposer<T>
extends SequenceComposer<JSONComposer<T>>

Root-level composer object that acts as streaming "builder" object, using an underlying JsonGenerator object. This is similar to ArrayComposer, but does not have parent composer (so no end() method), but does implement Closeable
