Class ConstructorDetector
java.lang.Object
edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.cfg.ConstructorDetector
- All Implemented Interfaces:
Serializable
Configurable handler used to select aspects of selecting
constructor to use as "Creator" for POJOs.
Defines the API for handlers, a pre-defined set of standard instances
and methods for constructing alternative configurations.
- Since:
- 2.12

Nested Class Summary
Modifier and TypeClassDescriptionstatic enum
Definition of alternate handling modes of single-argument constructors that are annotated withJsonCreator
but without "mode" definition (or explicit name for the argument): this is the case where two interpretations are possible -- "properties" (in which case the argument is named parameter of a JSON Object) and "delegating (in which case the argument maps to the whole JSON value). -

shouldIntrospectorImplicitConstructors
Accessor that combines checks for whether implicit creators are allowed and, if so, whether JDK type constructors are allowed (if type is JDK type) to determine whether implicit constructor detection should be enabled for given type or not.- Parameters:
rawType
- Value type to consider- Returns:
- True if implicit constructor detection should be enabled; false if not
-
