Methods

Modifier and Type	Method and Description
void	actionPerformed(java.awt.event.ActionEvent event) Handles action events.
void	dragInitial(PvPickEvent event) Drag an arbitrary point along a geometry, point may lie inside an element.
java.lang.String	getFileName() Get current file name.
void	init() Initialize and reset project, stops the running animation if any.
boolean	load() Loads geometry via PjImportModel and then calls load().
void	pickInitial(PvPickEvent event) Pick an arbitrary point on a geometry, point may lie inside an element.
void	reset()
void	setFileName(java.lang.String fullFileName) Sets filename from outside of this project.
void	setGeometry(PgElementSet geom) Sets the geometry loaded from PjImportModel and then triangulates, updates the number of elements, gets a vector field and fits that all in the display.
void	start() Start project with loading geometry from file.
static int	translate(PgPolygonOnElementSet poly, double end, PdBaryDir vector, PdBary outbase, PdBaryDir outvec) Parallel translate a given vector along a polygon on elementSet.
boolean	update(java.lang.Object event) Update all inspector panels, send update to all registered update listeners and finally update parent.

Constructor Detail

PjTranslation

public PjTranslation()

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

reset

public void reset()

start

public void start()

Start project with loading geometry from file.

Overrides:

start in class PjProject

See Also:

PvViewerIf.start(), PjProject.isEnabledAutoFit()

getFileName

public java.lang.String getFileName()

Get current file name.

setFileName

public void setFileName(java.lang.String fullFileName)

Sets filename from outside of this project. Replaces the default file name. Must call load() after setting the file name.

Parameters:

fullFileName - fully specified file name including code base, or URL.

See Also:

load()

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent event)

Handles action events.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

load

public boolean load()

Loads geometry via PjImportModel and then calls load().

See Also:

setGeometry(PgElementSet)

setGeometry

public void setGeometry(PgElementSet geom)

Sets the geometry loaded from PjImportModel and then triangulates, updates the number of elements, gets a vector field and fits that all in the display.

update

public boolean update(java.lang.Object event)

Description copied from class: PsObject

Update all inspector panels, send update to all registered update listeners and finally update parent. Each of those updates has this object as event independent of the argument of this method.

Central update method of this object. Must be overwritten if this class receives unknown events, say, from new children. Any subclass must class invoke super.update(event) on all events it does handle itself.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)

dragInitial

public void dragInitial(PvPickEvent event)

Description copied from class: PjProject

Drag an arbitrary point along a geometry, point may lie inside an element. This method invokes pickInitial(PvPickEvent) and should be overwritten.

Specified by:

dragInitial in interface PvPickListenerIf

Overrides:

dragInitial in class PjProject

Parameters:

event - Pick event issued by the display

See Also:

PvPickListenerIf

pickInitial

public void pickInitial(PvPickEvent event)

Description copied from class: PjProject

Pick an arbitrary point on a geometry, point may lie inside an element. This method does nothing and must be overwritten.

Specified by:

pickInitial in interface PvPickListenerIf

Overrides:

pickInitial in class PjProject

Parameters:

event - Pick event issued by the display

See Also:

PvPickListenerIf

translate

public static int translate(PgPolygonOnElementSet poly,
            double end,
            PdBaryDir vector,
            PdBary outbase,
            PdBaryDir outvec)

Parallel translate a given vector along a polygon on elementSet. The vector is given at the first vertex of the polygon.

Parameters:

poly - polygon on elementSet

end - distance to which the vector is translated

vector - initial vector as barycentric direction

outbase - base point of translated vector in barycentric coordinates

outvec - translated vector as barycentric direction

Returns:

element index which contains the translated vector.
