      info.monitorenter.gui.chart.io.RandomDataCollectorOffset

All Implemented Interfaces:

java.lang.Runnable

public class RandomDataCollectorOffset
extends ADataCollector

A proof of concept dummy implementation for the supertype.

Only collects random values with timestamp on the x axis. The timestamp is related to the time when this instance is instantiated to make it a lower value (offset to start). implementation for exact timestamps that may be formatted with java.text.DateFormat instances.

Constructor Detail

RandomDataCollectorOffset

public RandomDataCollectorOffset(ITrace2D trace,
                                 int latency)

Creates a collector that collectes every latency ms a point and adds it to the trace.

Parameters:

trace - the trace to add points to.

latency - the interval for collection of points.

Method Detail

collectData

public ITracePoint2D collectData()

Description copied from class: ADataCollector

Override this method. It will be invoked in intervals of the configured latency time. The TracePoint2D that is returned will be added to the constructor given ITrace2D.

Keep your implementation fast. If the computations performed here take longer than the latency time that desired refresh rate will not be reached.

Specified by:

collectData in class ADataCollector

Returns:

the collected point.
