Introduction

In this page you can find the example usage for com.fasterxml.jackson.core ObjectCodec readValue.

Prototype

public abstract <T> T readValue(JsonParser jp, ResolvedType valueType)
        throws IOException, JsonProcessingException;

Document

Method to deserialize JSON content into a POJO, type specified with fully resolved type object (so it can be a generic type, including containers like java.util.Collection and java.util.Map ).
