java.lang.Objectorg.codehaus.jackson.map.AnnotationIntrospector
public abstract class AnnotationIntrospector
Abstract class that defines API used for introspecting annotation-based configuration for serialization and deserialization. Separated so that different sets of annotations can be supported, and support plugged-in dynamically.
Nested Class Summary | |
---|---|
static class |
AnnotationIntrospector.Pair
Helper class that allows using 2 introspectors such that one introspector acts as the primary one to use; and second one as a fallback used if the primary does not provide conclusive or useful result for a method. |

Method for getting a serializer definition on specified method or field. |
abstract String |
findSettablePropertyName(AnnotatedMethod am)
Method for checking whether given method has an annotation that suggests property name associated with method that may be a "setter". |

Method for locating annotation-specified subtypes related to annotated entity (class, method, field). |
abstract String |
findTypeName(AnnotatedClass ac)
Method for checking if specified type has explicit name. |
abstract TypeResolverBuilder<?> |
findTypeResolver(AnnotatedClass ac,
JavaType baseType)
Method for checking if given class has annotations that indicate that specific type resolver is to be used for handling instances. |
abstract boolean |
hasAnySetterAnnotation(AnnotatedMethod am)
Method for checking whether given method has an annotation that suggests that the method is to serve as "any setter"; method to be used for setting values of any properties for which no dedicated setter method is found. |
abstract boolean |
hasAsValueAnnotation(AnnotatedMethod am)
Method for checking whether given method has an annotation that suggests that the return value of annotated method should be used as "the value" of the object instance; usually serialized as a primitive value such as String or number. |
abstract boolean |
