Interface JsonReader.ClassFactory

All Known Implementing Classes:

AbstractTemporalFactory, CalendarFactory, DateFactory, EnumClassFactory, JsonReader.CollectionFactory, JsonReader.MapFactory, LocalDateFactory, LocalDateTimeFactory, LocalTimeFactory, OffsetDateTimeFactory, OffsetTimeFactory, SqlDateFactory, StackTraceElementFactory, ThrowableFactory, TimeZoneFactory, YearFactory, YearMonthFactory, ZonedDateTimeFactory, ZoneOffsetFactory

Enclosing class:

JsonReader

public static interface JsonReader.ClassFactory

Subclass this interface and create a class that will return a new instance of the passed in Class (c). Your factory subclass will be called when json-io encounters an instance of (c) which you reigister with JsonReader.assignInstantiator(). Use the passed in JsonObject o which is a JsonObject to source values for the construction of your class.

Method Summary

Modifier and Type	Method and Description
default boolean	isObjectFinal()
default Object	newInstance(Class<?> c, JsonObject jObj) Implement this method to return a new instance of the passed in Class.

Method Detail

newInstance

default Object newInstance(Class<?> c,
                           JsonObject jObj)

Implement this method to return a new instance of the passed in Class. Use the passed in JsonObject to supply values to the construction of the object.

Parameters:

c - Class of the object that needs to be created

jObj - JsonObject (if primitive type do jObj.getPrimitiveValue();

Returns:

a new instance of C. If you completely fill the new instance using the value(s) from object, and no further work is needed for construction, then override the isObjectFinal() method below and return true.

isObjectFinal

default boolean isObjectFinal()

Returns:

true if this object is instantiated and completely filled using the contents from the Object object [a JsonOject or value]. In this case, no further processing will be performed on the instance. If the object has sub-objects (complex fields), then return false so that the JsonReader will continue on filling out the remaining portion of the object.
