public class DefaultDeserializer
Default deserializer that expects the input to match the current classpath beans.
This uses the standard MetaBean, MetaProperty and BeanBuilder.
Implementations must be thread-safe singletons.

public MetaBean findMetaBean(Class<?> beanType)
SerDeserializerIf the type is not a bean, then null may be returned.
findMetaBean in interface SerDeserializerbeanType - the type being processed, not null
public BeanBuilder<?> createBuilder(Class<?> beanType,
MetaBean metaBean)
SerDeserializer
This is normally a BeanBuilder however any type may be returned.
createBuilder in interface SerDeserializerbeanType - the type being processed, not nullmetaBean - the meta-bean, null if not a bean type
public MetaProperty<?> findMetaProperty(Class<?> beanType,
MetaBean metaBean,
String propertyName)
SerDeserializerReturn null if a property has been deleted, which will cause the parser to discard the property.
Return a non-null meta-property to parse the property. If the property was renamed, or had a type change, then the meta-property should match the property as originally stored.
findMetaProperty in interface SerDeserializerbeanType - the type being processed, not nullmetaBean - the meta-bean, null if not a bean typepropertyName - the property name being parsed, not null
public void setValue(BeanBuilder<?> builder,
MetaProperty<?> metaProp,
Object value)
SerDeserializer
setValue in interface SerDeserializerbuilder - the builder, null if not interested in the parse progressmetaProp - the meta-property, not nullvalue - the parsed value, may be null
public Object build(Class<?> beanType,
BeanBuilder<?> builder)
SerDeserializerThis method finishes the builder and returns the final object. The migrator could validate or manipulate data here once all data is parsed, for example to default a missing field.
