Class RrdDoubleArray<U extends RrdUpdater<U>>

java.lang.Object

org.rrd4j.core.RrdPrimitive<U>

org.rrd4j.core.RrdDoubleArray<U>

Type Parameters:

U - The type of RrdUpdater this primitive belongs to

class RrdDoubleArray<U extends RrdUpdater<U>>
extends RrdPrimitive<U>

RRD primitive type for handling arrays of double values.

This class provides methods to store and retrieve arrays of double values in RRD files. It extends RrdPrimitive to handle the low-level storage operations while providing array-specific access methods.
