public static class Deserializers.Base extends Object implements Deserializers
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).Deserializers.Base

Deserializers
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).

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)
