Classes in org.rrd4j.data used by org.rrd4j

Class and Description
Variable Abstract class for extracting single values from data sets (VDEF in rrdtool). Provides statistical calculations on RRD values and supports custom computation methods for advanced data processing.

Classes in org.rrd4j.data used by org.rrd4j.core

Class and Description
Aggregates Deprecated. Use Variable with DataProcessor.addDatasource(String, String, Variable) instead.
IPlottable Interface for custom data sources used in RRD graphs. Implement this interface to create custom datasources that can be passed to RrdGraphDef for graphing operations.

Classes in org.rrd4j.data used by org.rrd4j.data

Class and Description
Aggregates Deprecated. Use Variable with DataProcessor.addDatasource(String, String, Variable) instead.
DataProcessor Class which should be used for all calculations based on the data fetched from RRD files.
Def RRD DEF (Data Source Definition) implementation. Represents a data source defined in an RRD file with specific name, consolidation function, and backend configuration.
IPlottable Interface for custom data sources used in RRD graphs. Implement this interface to create custom datasources that can be passed to RrdGraphDef for graphing operations.
LinearInterpolator.Method A enumeration of interpolation methods
NonRrdSource Interface for non-RRD data sources. Represents computed or derived data sources that don't directly reference RRD data but calculate values from other sources.
Plottable Deprecated. Use implementations of IPlottable instead
Source Abstract base class for RRD data sources. Provides common functionality for storing and managing time-series data with timestamps and values.
