java.lang.Object

com.google.gson.TypeAdapter<T>

com.sap.cloud.sdk.s4hana.datamodel.odata.adapter.AbstractCalendarAdapter<T>

Type Parameters:

T - The type this adapter should parse.

Direct Known Subclasses:

LocalDateTimeAdapter, LocalTimeAdapter, ZonedDateTimeAdapter

public abstract class AbstractCalendarAdapter<T>
extends com.google.gson.TypeAdapter<T>

Abstract base class to be used to easily parse fields which can be read as a Calendar object as a Gson TypeAdapter.

This may be used to specify an adapter for the new Java date API (e.g. LocalDateTime) based on a common conversion logic. This way the logic is split the following way:

General Conversion logic	AbstractTypeConverter subclasses (*CalendarConverter)
Gson Adapter	AbstractCalendarAdapter subclasses
Jackson (De)Serializer	AbstractJacksonCalendar(De)Serializer and subclasses
