java.lang.Object

info.monitorenter.gui.chart.rangepolicies.ARangePolicy

All Implemented Interfaces:

IRangePolicy, java.io.Serializable

Direct Known Subclasses:

RangePolicyFixedViewport, RangePolicyHighestValues, RangePolicyHighestValuesForcedMin, RangePolicyMinimumViewport, RangePolicyUnbounded

public abstract class ARangePolicy
extends java.lang.Object
implements IRangePolicy

A default superclass for IRangePolicy implementations that adds support for setting and getting ranges.

Should be used by any implementation that really works on the data of ranges (not unbounded ranges). Subclasses should access the internal member range or use getRange().
