Class FastMedicalModel

java.lang.Object
com.arbergashi.charts.model.FastMedicalModel
All Implemented Interfaces:
ChartModel
Direct Known Subclasses:
CircularFastMedicalModel
public class FastMedicalModel extends Object implements ChartModel
Optimized model for real-time medical data (ECG, EEG).

Uses primitive arrays with dynamic resizing. Thread-safe for append operations (single-writer, multiple-reader scenario).

  • Method Details

    • addPoint

      public void addPoint(double x, double y)
      Adds a new point. Thread-safe.

    • addPoints

      public void addPoints(double[] x, double[] y)
      Adds multiple points efficiently (bulk operation).

    • clear

      public void clear()

    • getName

      public String getName()
      Description copied from interface: ChartModel
      Returns the title of the data series.
      Specified by:
      getName in interface ChartModel
      Returns:
      Name of the series

    • getPointCount

      public int getPointCount()
      Description copied from interface: ChartModel
      Returns the number of data points.
      Specified by:
      getPointCount in interface ChartModel
      Returns:
      count

    • getXData

      public double[] getXData()
      Description copied from interface: ChartModel
      Direct access to the X-coordinate array.

      Framework contract: Implementations may return either:

      Consumers must never assume getXData().length == getPointCount(). Always bound iteration by the logical size:

      int n = Math.min(model.getPointCount(), model.getXData().length);

      Performance note: If you need strict size and immutability semantics, use a model implementation that returns copies (e.g. DefaultChartModel).

      Specified by:
      getXData in interface ChartModel
      Returns:
      X values array (may be larger than logical size)

    • getYData

      public double[] getYData()
      Description copied from interface: ChartModel
      Direct access to the Y-coordinate array.

      Warning: For performance reasons, the internal array is often returned. Do not modify!

      Specified by:
      getYData in interface ChartModel
      Returns:
      double array of Y values

    • trimToSize

      public void trimToSize()

    • addChangeListener

      Registers a listener for data changes.
      Specified by:
      addChangeListener in interface ChartModel
      Parameters:
      listener - The listener

    • removeChangeListener

      public void removeChangeListener(ChartModel.ChartModelListener listener)
      Description copied from interface: ChartModel
      Removes a listener.
      Specified by:
      removeChangeListener in interface ChartModel
      Parameters:
      listener - The listener
