Deserializers.Base (jackson-databind 2.3.2)

java.lang.Object
- com.fasterxml.jackson.databind.deser.Deserializers.Base

All Implemented Interfaces:

Deserializers

Direct Known Subclasses:

CoreXMLDeserializers

Enclosing interface:

Deserializers
```
public static class Deserializers.Base
extends Object
implements Deserializers
```
Basic Deserializers implementation that implements all methods but provides no deserializers. Its main purpose is to serve as a base class so that sub-classes only need to override methods they need, as most of the time some of methods are not needed (especially enumeration and array deserializers are very rarely overridden).

```
    Description copied from interface: Deserializers
    
    Method called to locate serializer for specified array type.
    Deserializer for element type may be passed, if configured explicitly at higher level (by annotations, typically), but usually are not. Type deserializer for element is passed if one is needed based on contextual information (annotations on declared element class; or on field or method type is associated with).
    
    Specified by:
    
    findArrayDeserializer in interface Deserializers
    
    Parameters:
    type - Type of array instances to deserialize
    config - Configuration in effect
    beanDesc - Definition of the enumeration type that contains class annotations and other information typically needed for building deserializers
    elementTypeDeserializer - If element type needs polymorphic type handling, this is the type information deserializer to use; should usually be used as is when constructing array deserializer.
    elementDeserializer - Deserializer to use for elements, if explicitly defined (by using annotations, for exmple). May be null, in which case it should be resolved here (or using ResolvableDeserializer callback)
    
    Returns:
    Deserializer to use for the type; or null if this provider does not know how to construct it
    
    Throws:
    
    JsonMappingException

    Description copied from interface: Deserializers
    
    Method called to locate deserializer for specified Map type.
    Deserializer for element type may be passed, if configured explicitly at higher level (by annotations, typically), but usually are not. Type deserializer for element is passed if one is needed based on contextual information (annotations on declared element class; or on field or method type is associated with).
    Similarly, a KeyDeserializer may be passed, but this is only done if there is a specific configuration override (annotations) to indicate instance to use. Otherwise null is passed, and key deserializer needs to be obtained later during resolution (using ResolvableDeserializer.resolve(com.fasterxml.jackson.databind.DeserializationContext)).

    Parameters:
    type - Type of Map instances to deserialize
    config - Configuration in effect
    beanDesc - Definition of the enumeration type that contains class annotations and other information typically needed for building deserializers
    keyDeserializer - Key deserializer use, if it is defined via annotations or other configuration; null if default key deserializer for key type can be used.
    elementTypeDeserializer - If element type needs polymorphic type handling, this is the type information deserializer to use; should usually be used as is when constructing array deserializer.
    elementDeserializer - Deserializer to use for elements, if explicitly defined (by using annotations, for exmple). May be null, in which case it should be resolved here (or using ResolvableDeserializer callback)
