Class ARangePolicy
java.lang.Object
info.monitorenter.gui.chart.rangepolicies.ARangePolicy
- All Implemented Interfaces:
IRangePolicy,Serializable
- Direct Known Subclasses:
RangePolicyFixedViewport,RangePolicyHighestValues,RangePolicyHighestValuesForcedMin,RangePolicyMinimumViewport,RangePolicyUnbounded
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().
