Class PredictionPlotData

java.lang.Object

org.lsst.ccs.subsystem.shutter.gui.PredictionPlotData

All Implemented Interfaces:

data.DiscretePlotData, data.MutablePlotData, data.PlotData

public class PredictionPlotData
extends Object
implements data.DiscretePlotData, data.MutablePlotData

Contains the data set for a predicted trajectory of a blade set. This is a mutable data set whose contents may be removed or added to. Those objects needing to use this data set must register with the data set as plot-data listeners in order to be informed when the contents of the data set have changed.

Each data point has four dimensions: time, acceleration, velocity and position. The times are relative to the start of motion.

This class isn't thread safe and methods should be called only from the event dispatch thread, for example via invokeLater.

PredictionPlotData

public PredictionPlotData()

Method Detail

reset

public void reset()

Clears away any old data and cause the plot pane to be repainted.

addData

public void addData(List<PredictedPosition> pos,
                    org.lsst.ccs.utilities.taitime.CCSTimeStamp t0)

Adds new data and causes the plot pane to be repainted. All the data for the plot must be added at once or the scaling of acceleration and velocity won't work properly.

Acceleration values will be scaled by dividing by the max absolute value. Likewise for the velocity values. Position values are assumed to be already scaled so that a full stroke has size 1.0.

Parameters:

pos - a stream of PredictedPosition from simulated motion

getNPoints

public int getNPoints()

Gets the count of data points currently stored.

Specified by:

getNPoints in interface data.DiscretePlotData

Returns:

The number of points.

getNDimensions

public int getNDimensions()

Gets the number of dimensions, that is, the number of values per data point.

Specified by:

getNDimensions in interface data.DiscretePlotData

Specified by:

getNDimensions in interface data.PlotData

Returns:

The dimension count.

names

public String names(int index)

Gets the name of one of the dimensions of a data point.

Specified by:

names in interface data.DiscretePlotData

Parameters:

index - The dimension index d, where 0 <= d < getNDimensions().

Returns:

The name of the requested dimension.

Throws:

IndexOutOfBoundsException - if index is out of bounds.

types

public Class types(int index)

Returns the data type (class object) for the values of a given dimension.

Specified by:

types in interface data.DiscretePlotData

Parameters:

index - The dimension index, ignored by this method.

Returns:

Double.TYPE, always.

getValue

public void getValue(org.freehep.util.Value value,
                     int dim,
                     int index)

Gets the value of a given data point at a given dimension.

Specified by:

getValue in interface data.DiscretePlotData

Parameters:

value - A generic container for values of primitive type. In this case it will always be given a double value, so use value.getDouble().

dim - The dimension index d, where 0 <= d < getNDimensions().

index - The data point index i, where 0 <= i < getNPoints(.

Throws:

IndexOutOfBoundsException - if either dim or index is out of bounds.

getMetaData

public data.MetaData getMetaData()

Gets the metadata for this plot data object.

Specified by:

getMetaData in interface data.PlotData

Returns:

null since there is no metadata.

getTitle

public String getTitle()

Specified by:

getTitle in interface data.PlotData

getSuggestedRange

public data.SuggestedRange getSuggestedRange()

Specified by:

getSuggestedRange in interface data.PlotData

addPlotDataListener

public void addPlotDataListener(data.PlotDataListener listener)

Specified by:

addPlotDataListener in interface data.MutablePlotData

removePlotDataListener

public void removePlotDataListener(data.PlotDataListener listener)

Specified by:

removePlotDataListener in interface data.MutablePlotData

lock

public Object lock()

Locking isn't implemented.

Specified by:

lock in interface data.MutablePlotData

Returns:

nothing.

Throws:

UnsupportedOperationException
