Class AbstractTemporalFactory<T extends TemporalAccessor>

java.lang.Object

com.cedarsoftware.util.io.factory.AbstractTemporalFactory<T>

All Implemented Interfaces:

JsonReader.ClassFactory

Direct Known Subclasses:

InstantFactory, LocalDateFactory, LocalDateTimeFactory, LocalTimeFactory, MonthDayFactory, OffsetDateTimeFactory, OffsetTimeFactory, YearFactory, YearMonthFactory, ZonedDateTimeFactory

public abstract class AbstractTemporalFactory<T extends TemporalAccessor>
extends Object
implements JsonReader.ClassFactory

Abstract class to help create temporal items.

All custom writers for json-io subclass this class. Special writers are not needed for handling user-defined classes. However, special writers are built/supplied by json-io for many of the primitive types and other JDK classes simply to allow for a more concise form.

Method Detail

newInstance

public T newInstance(Class<?> c,
                     JsonObject jObj,
                     ReaderContext context)

Description copied from interface: JsonReader.ClassFactory

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.

Specified by:

newInstance in interface JsonReader.ClassFactory

Parameters:

c - Class of the object that needs to be created

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

context - ReaderContext for creating objects an getting read options

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.

convertToZonedDateTime

protected ZonedDateTime convertToZonedDateTime(String s)

fromString

protected abstract T fromString(String s)

fromNumber

protected T fromNumber(Number l)

fromJsonObject

protected abstract T fromJsonObject(JsonObject job,
                                    ReaderContext context)

isObjectFinal

public boolean isObjectFinal()

Specified by:

isObjectFinal in interface JsonReader.ClassFactory

Returns:

true if this object is instantiated and completely filled using the contents from the Object [a JsonObject 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.
