Interface DateValue

All Superinterfaces:

AnalyticsValue, AnalyticsValueStream, DateValueStream, LongValue, LongValueStream

All Known Subinterfaces:

DateValue.CastingDateValue

All Known Implementing Classes:

ConstantDateValue, DateField, DateValue.AbstractDateValue

public interface DateValue
extends DateValueStream, LongValue

A single-valued analytics value that can be represented as a date.

The back-end production of the value can change inbetween calls to getDate() and AnalyticsValue.exists(), resulting in different values on each call.

NOTE: Most date expressions work with the long representation of the date, so that less objects need to be created during execution.
