## Class ObjectReader

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

- All Implemented Interfaces:
    com.fasterxml.jackson.core.Versioned, java.io.Serializable

      public class ObjectReader
      extends com.fasterxml.jackson.core.ObjectCodec
      implements com.fasterxml.jackson.core.Versioned, java.io.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.

- - ### 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 com.fasterxml.jackson.core.JsonFactory _parserFactory

      Factory used for constructing `JsonGenerator`s

    - #### _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<java.lang.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 java.lang.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 can not be modified because array size is immutable.

    - #### _schema

          protected final com.fasterxml.jackson.core.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 can not be detect reliably (as per detector settings), a `JsonParseException` will be thrown).

      Since:
        2.1

    - #### _rootDeserializers

          protected final java.util.concurrent.ConcurrentHashMap<JavaType,JsonDeserializer<java.lang.Object>> _rootDeserializers

      Root-level cached deserializers. Passed by `ObjectMapper`, shared with it.

      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 can not 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

                                               com.fasterxml.jackson.core.JsonProcessingException

      Method for reading 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` but rather to the token following it.

                                               com.fasterxml.jackson.core.JsonProcessingException

      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).
