ElementTrail

public ElementTrail()

Method Details

addPoint

public void addPoint(double x,
 double y,
 double z)

Description copied from interface: ElementTrail

Adds a new (x,y,z) point to the trail.

Specified by:

addPoint in interface ElementTrail

Parameters:

x - double

y - double

z - double

addPoint

public void addPoint(double[] point)

Description copied from interface: ElementTrail

Adds a new double[] point to the trail.

Specified by:

addPoint in interface ElementTrail

Parameters:

point - double[] The array with the coordinates of the point. If the length of the array is 2, the coordinates are asumed to be X and Y (Z=0). If it is 3, then X, Y, and Z (as usual).

moveToPoint

public void moveToPoint(double x,
 double y,
 double z)

Description copied from interface: ElementTrail

Starts a new (x,y,z) trail segment by moving to a new point without drawing. (Equivalent to setting the connected flag to false and adding one singlepoint, then setting the flag back to true.)

Specified by:

moveToPoint in interface ElementTrail

Parameters:

x - double

y - double

z - double

setMaximumPoints

public void setMaximumPoints(int maximum)

Description copied from interface: ElementTrail

Sets the maximum number of points for the trail. Once the maximum is reached, adding a new point will cause remotion of the first one. This is useful to keep trails down to a reasonable size, since very long trails can slow down the rendering (in certain implementations). If the value is 0 (the default) the trail grows forever without discarding old points.

Specified by:

setMaximumPoints in interface ElementTrail

Parameters:

maximum - int

getMaximumPoints

public int getMaximumPoints()

Description copied from interface: ElementTrail

Returns the maximum number of points allowed for the trail

Specified by:

getMaximumPoints in interface ElementTrail

Returns:

int

setConnected

public void setConnected(boolean connected)

Description copied from interface: ElementTrail

Sets the connected flag. Successive points are connected by a segment if this flag is true. Each point is marked as a colored pixel if the trail is not connected. Setting it temporarily to false helps create discontinuous trails.

Specified by:

setConnected in interface ElementTrail

Parameters:

connected - boolean

isConnected

public boolean isConnected()

Description copied from interface: ElementTrail

Gets the connected flag.

Specified by:

isConnected in interface ElementTrail

See Also:

• ElementTrail.setConnected(boolean)

clear

public void clear()

Description copied from interface: ElementTrail

Clears all points from the trail.

Specified by:

clear in interface ElementTrail

setXLabel

public void setXLabel(String _label)

Description copied from interface: ElementTrail

Sets the label of the X coordinate when the data is displayed in a table

Specified by:

setXLabel in interface ElementTrail

setYLabel

public void setYLabel(String _label)

Description copied from interface: ElementTrail

Sets the label of the Y coordinate when the data is displayed in a table

Specified by:

setYLabel in interface ElementTrail

setZLabel

public void setZLabel(String _label)

Description copied from interface: ElementTrail

Sets the label of the Z coordinate when the data is displayed in a table

Specified by:

setZLabel in interface ElementTrail

getNumberOfPoints

public int getNumberOfPoints()

setGhostPoint

public void setGhostPoint(double[] _point,
 boolean _connected)

Description copied from interface: ElementTrail

Sets a temporary point that is displayed as the last point of the trail but is not meant to be a permanent part of the trail. The point can be changed at will and even removed (by passing a null array as point), but if not null, it is always drawn following the last effective point of the trail. This is used by MultiTrail to implement the skip parameter.

Specified by:

setGhostPoint in interface ElementTrail

Parameters:

_point - the double[3] data with the point. null if there is no such point

_connected - whether this point is connected to the previous one

getExtrema

public void getExtrema(double[] min,
 double[] max)

setID

public void setID(int id)

Description copied from interface: Data

Sets the ID number of this Data

Specified by:

setID in interface Data

Parameters:

id - the ID number

getID

public int getID()

Description copied from interface: Data

Returns a unique identifier for this Data

Specified by:

getID in interface Data

Returns:

the ID number

getData2D

public double[][] getData2D()

Description copied from interface: Data

Gets a 2D array of data. The first column, double[0][] often contains x-values; Remaining columns often contain y values. May return null if data not yet generated or object does not support 2D data.

Specified by:

getData2D in interface Data

Returns:

double[][]

getData3D

public double[][][] getData3D()

Description copied from interface: Data

Gets a 3D array of data. May return null if data not yet generated or object does not support 3D data.

Specified by:

getData3D in interface Data

Returns:

double[][][]

getColumnNames

public String[] getColumnNames()

Description copied from interface: Data

The column names to be used in the data display tool

Specified by:

getColumnNames in interface Data

Returns:

an array of names

getLineColors

public Color[] getLineColors()

Description copied from interface: Data

Line color to use for this data

Specified by:

getLineColors in interface Data

Returns:

a color

getFillColors

public Color[] getFillColors()

Description copied from interface: Data

Fill color to use for this data

Specified by:

getFillColors in interface Data

Returns:

a color

getDataList

public List<Data> getDataList()

Description copied from interface: Data

Some Data objects (e.g., a Group) do not contain data, but a list of Data objects which do. This method is used by Data displaying tools to create as many pages as needed.

Specified by:

getDataList in interface Data

Returns:

a list of Data objects, or null if this object contains data

getDatasets

public ArrayList<Dataset> getDatasets()

Description copied from interface: Data

Gets a list of OSP Datasets. May return null if data not yet generated or object does not support Datasets.

Specified by:

getDatasets in interface Data

Returns:

list of Datasets

getLoader

public static XML.ObjectLoader getLoader()

Returns an XML.ObjectLoader to save and load object data.

Returns:

the XML.ObjectLoader
