ObjectReader (jackson-databind 2.10.5.1)

java.lang.Object
- com.fasterxml.jackson.core.TreeCodec
- - com.fasterxml.jackson.core.ObjectCodec
  - - com.fasterxml.jackson.databind.ObjectReader

All Implemented Interfaces:

Versioned, Serializable
```
public class ObjectReader
extends ObjectCodec
implements Versioned, Serializable
```
Builder object that can be used for per-serialization configuration of deserialization parameters, such as root type to use or object to update (instead of constructing new instance).
Uses "mutant factory" pattern so that instances are immutable (and thus fully thread-safe with no external synchronization); new instances are constructed for different configurations. Instances are initially constructed by ObjectMapper and can be reused, shared, cached; both because of thread-safety and because instances are relatively light-weight.
NOTE: this class is NOT meant as sub-classable (with Jackson 2.8 and above) by users. It is left as non-final mostly to allow frameworks that require bytecode generation for proxying and similar use cases, but there is no expecation that functionality should be extended by sub-classing.

- Field Detail
  - _config
```
protected final DeserializationConfig _config
```
    General serialization configuration settings; while immutable, can use copy-constructor to create modified instances as necessary.
  - _context
```
protected final DefaultDeserializationContext _context
```
    Blueprint instance of deserialization context; used for creating actual instance when needed.
  - _parserFactory
```
protected final JsonFactory _parserFactory
```
    Factory used for constructing JsonGenerators
  - _unwrapRoot
```
protected final boolean _unwrapRoot
```
    Flag that indicates whether root values are expected to be unwrapped or not
  - _valueType
```
protected final JavaType _valueType
```
    Declared type of value to instantiate during deserialization. Defines which deserializer to use; as well as base type of instance to construct if an updatable value is not configured to be used (subject to changes by embedded type information, for polymorphic types). If _valueToUpdate is non-null, only used for locating deserializer.
  - _rootDeserializer
```
protected final JsonDeserializer<Object> _rootDeserializer
```
    We may pre-fetch deserializer as soon as _valueType is known, and if so, reuse it afterwards. This allows avoiding further deserializer lookups and increases performance a bit on cases where readers are reused.
    
    Since:
    
    2.1
  - _valueToUpdate
```
protected final Object _valueToUpdate
```
    Instance to update with data binding; if any. If null, a new instance is created, if non-null, properties of this value object will be updated instead. Note that value can be of almost any type, except not ArrayType; array types cannot be modified because array size is immutable.
  - _schema
```
protected final FormatSchema _schema
```
    When using data format that uses a schema, schema is passed to parser.
  - _injectableValues
```
protected final InjectableValues _injectableValues
```
    Values that can be injected during deserialization, if any.
  - _dataFormatReaders
```
protected final DataFormatReaders _dataFormatReaders
```
    Optional detector used for auto-detecting data format that byte-based input uses.
    NOTE: If defined non-null, readValue() methods that take Reader or String input will fail with exception, because format-detection only works on byte-sources. Also, if format cannot be detect reliably (as per detector settings), a JsonParseException will be thrown).
    
    Since:

    Fluent factory method for constructing a reader that will try to auto-detect underlying data format, using specified list of JsonFactory instances, and default DataFormatReaders settings (for customized DataFormatReaders, you can construct instance yourself). to construct appropriate JsonParser for actual parsing.
    Note: since format detection only works with byte sources, it is possible to get a failure from some 'readValue()' methods. Also, if input cannot be reliably (enough) detected as one of specified types, an exception will be thrown.
    Note: not all JsonFactory types can be passed: specifically, ones that require "custom codec" (like XML factory) will not work. Instead, use method that takes ObjectReader instances instead of factories.
    
    Parameters:
    
    readers - Data formats accepted, in decreasing order of priority (that is, matches checked in listed order, first match wins)
    
    Returns:
    
    Newly configured writer instance

    Method reads a sequence of Objects from parser stream. Sequence can be either root-level "unwrapped" sequence (without surrounding JSON array), or a sequence contained in a JSON Array. In either case JsonParser MUST point to the first token of the first element, OR not point to any token (in which case it is advanced to the next token). This means, specifically, that for wrapped sequences, parser MUST NOT point to the surrounding START_ARRAY (one that contains values to read) but rather to the token following it which is the first token of the first value to read.

public <T> MappingIterator<T> readValues(InputStream src)
                                  throws IOException
```
    Method for reading sequence of Objects from parser stream.
    Sequence can be either wrapped or unwrapped root-level sequence: wrapped means that the elements are enclosed in JSON Array; and unwrapped that elements are directly accessed at main level. Assumption is that iff the first token of the document is START_ARRAY, we have a wrapped sequence; otherwise unwrapped. For wrapped sequences, leading START_ARRAY is skipped, so that for both cases, underlying JsonParser will point to what is expected to be the first token of the first element.
    Note that the wrapped vs unwrapped logic means that it is NOT possible to use this method for reading an unwrapped sequence of elements written as JSON Arrays: to read such sequences, one has to use readValues(JsonParser), making sure parser points to the first token of the first element (i.e. the second START_ARRAY which is part of the first element).
