Interface DoubleValue

All Superinterfaces:

AnalyticsValue, AnalyticsValueStream, DoubleValueStream

All Known Subinterfaces:

DoubleValue.CastingDoubleValue, FloatValue.CastingFloatValue, IntValue.CastingIntValue, LongValue.CastingLongValue

All Known Implementing Classes:

ConstantDoubleValue, ConstantFloatValue, ConstantIntValue, ConstantLongValue, CountFunction, DocCountFunction, DoubleField, DoubleValue.AbstractDoubleValue, FloatField, FloatValue.AbstractFloatValue, IntField, IntValue.AbstractIntValue, LongField, LongValue.AbstractLongValue, MeanFunction, MissingFunction, SumFunction, UniqueFunction

public interface DoubleValue
extends DoubleValueStream, AnalyticsValue

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

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