  - findSerializablePropertyName
```
public String findSerializablePropertyName(AnnotatedField af)
```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given member field represent a serializable logical property; and if so, returns the name of that property. Should return null if no annotation is found (indicating it is not a serializable field); otherwise a non-null String. If non-null value is returned, it is used as the property name, except for empty String ("") which is taken to mean "use the field name as is".

```
public Class<? extends JsonDeserializer<?>> findDeserializer(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    Method for getting a deserializer definition on specified method or field. Type of definition is either instance (of type JsonDeserializer) or Class (of type Class); if value of different type is returned, a runtime exception may be thrown by caller.
    Note: this variant was briefly deprecated for 1.7; but it turns out we really should not try to push BeanProperty through at this point

```
public Class<? extends KeyDeserializer> findKeyDeserializer(Annotated a)
```
    Description copied from class: AnnotationIntrospector
    
    Method for getting a deserializer definition for keys of associated Map property. Type of definition is either instance (of type JsonDeserializer) or Class (of type Class); if value of different type is returned, a runtime exception may be thrown by caller.

```
    Description copied from class: AnnotationIntrospector
    
    Method for accessing annotated type definition that a method can have, to be used as the type for serialization instead of the runtime type. Type must be a narrowing conversion (i.e.subtype of declared type). Declared return type of the method is also considered acceptable.

    Specified by:
    
    findDeserializationKeyType in class AnnotationIntrospector
    
    baseKeyType - Assumed key type before considering annotations

```
    Description copied from class: AnnotationIntrospector
    
    Method for accessing additional narrowing type definition that a method can have, to define more specific content type to use; content refers to Map values and Collection/array elements. It should be only be used with Map, Collection and array types.
    
    Specified by:
    
    findDeserializationContentType in class AnnotationIntrospector
    
    baseContentType - Assumed content (value) type before considering annotations
    propName - Logical property name of the property that uses type, if known; null for types not associated with property

public String findSettablePropertyName(AnnotatedMethod am)
```
    Description copied from class: AnnotationIntrospector
    
    Method for checking whether given method has an annotation that suggests property name associated with method that may be a "setter". Should return null if no annotation is found; otherwise a non-null String. If non-null value is returned, it is used as the property name, except for empty String ("") which is taken to mean "use standard bean name detection if applicable; method name if not".

    Overrides:
    
    hasCreatorAnnotation in class AnnotationIntrospector
