Class BeanPropertyIntrospector

java.lang.Object

com.fasterxml.jackson.jr.ob.impl.BeanPropertyIntrospector

public class BeanPropertyIntrospector
extends Object

Helper class that jackson-jr uses by default to introspect POJO properties (represented as POJODefinition) to build general POJO readers (deserializers) and writers (serializers).

Note that most of the usage is via ValueReaderLocator and ValueWriterLocator

Since:

2.11

derivePropertiesFromRecordConstructor

public static <P> Constructor<?> derivePropertiesFromRecordConstructor(Class<?> beanType,
 Map<String,P> propsByName,
 Function<String,P> propBuilder)

Gets canonical constructor of given types and adds properties to the map, derived from constructor parameters.

addNonRecordConstructors

public static void addNonRecordConstructors(Class<?> beanType,
 BeanConstructors constructors)

Adds all beanType's 0 and 1 argument declared constructors to constructors.

isGroovyMetaClass

protected static boolean isGroovyMetaClass(Class<?> clazz)

Helper method to detect Groovy's problematic metadata accessor type.

NOTE: Groovy MetaClass have cyclic reference, and hence the class containing it should not be serialized without either removing that reference, or skipping over such references.
