Class XYData

java.lang.Object

mds.wave.XYData

public class XYData
extends Object

Class XYData is the container of signals returned by WaveData instances. Code immplementing WaveData interface will use this class only via its constructor methods. Besides X and Y arrays, resolution and increasingX information is defined here. Resolution is computed in jScope as NumberOfSamples/XRange and compared with the declared resolution on the XYData instance in order to activate the asyncronous retrieval mechanism (that occurs when a resampled signal is zoomed and more resolution is required in the zoomed region). increasingX flag specifies whether the X samples are in increasing order. jScope handles dynamic resampling only when this flag is true.
