Introduction

In this page you can find the example usage for com.fasterxml.jackson.core JsonGenerator writeString.

Prototype

public abstract void writeString(SerializableString text) throws IOException, JsonGenerationException;

Document

Method similar to #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.
