DeserializationContext (jackson-databind 2.7.0-rc2 API)

java.lang.Object
- com.fasterxml.jackson.databind.DatabindContext
- - com.fasterxml.jackson.databind.DeserializationContext

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

DefaultDeserializationContext
```
public abstract class DeserializationContext
extends DatabindContext
implements Serializable
```
Context for the process of deserialization a single root-level value. Used to allow passing in configuration settings and reusable temporary objects (scrap arrays, containers).
Instance life-cycle is such that an partially configured "blueprint" object is registered with ObjectMapper (and ObjectReader, and when an actual instance is needed for deserialization, a fully configured instance will be created using a method in excented API of sub-class (DefaultDeserializationContext.createInstance(com.fasterxml.jackson.databind.DeserializationConfig, com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.InjectableValues)). Each instance is guaranteed to only be used from single-threaded context; instances may be reused iff no configuration has changed.
Defined as abstract class so that implementations must define methods for reconfiguring blueprints and creating instances.

```
    Method called for secondary property deserializers (ones NOT directly created to deal with an annotatable POJO property, but instead created as a component -- such as value deserializers for structured types, or deserializers for root values) to handle details of resolving ContextualDeserializer with given property context. Given that these deserializers are not directly related to given property (or, in case of root value property, to any property), annotations accessible may or may not be relevant.
    
    Parameters:
    prop - Property for which deserializer is used, if any; null when deserializing root values
    
    Throws:
    
    JsonMappingException

```
    Convenience method for parsing a Date from given String, using currently configured date format (accessed using MapperConfig.getDateFormat()).
    Implementation will handle thread-safety issues related to date formats such that first time this method is called, date format is cloned, and cloned instance will be retained for use during this deserialization round.

public <T> T readValue(JsonParser p,

```
    Convenience method that may be used by composite or container deserializers, for reading one-off values contained (for sequences, it is more efficient to actually fetch deserializer once for the whole collection).
    NOTE: when deserializing values of properties contained in composite types, rather use readPropertyValue(JsonParser, BeanProperty, Class); this method does not allow use of contextual annotations.
