Constructor Detail

RenderedGridMarks.Iterator

public RenderedGridMarks.Iterator()

Construct a mark iterator.

Method Detail

getIteratorPosition

public int getIteratorPosition()

Description copied from class: MarkIterator

Returns the current iterator position. A newly created MarkIterator will returns -1, since new iterators are initially positioned before the first mark.

Specified by:

getIteratorPosition in class MarkIterator

setIteratorPosition

public void setIteratorPosition(int n)

Moves the iterator to the specified index.

Specified by:

setIteratorPosition in class MarkIterator

Parameters:

n - The new position (0 for the first mark, 1 for the second one, etc.).

next

public boolean next()

Moves the iterator to the next mark.

Specified by:

next in class MarkIterator

Returns:

true if the new current mark is valid; false if there are no more marks.

position

public java.awt.geom.Point2D position()
                               throws org.opengis.referencing.operation.TransformException

Retourne les coordonn?es (x,y) d'un point de la grille. Les coordonn?es x et y seront exprim?es selon le syst?me de coordonn?es du grid coverage. Si une d?cimation a ?t? sp?cifi?e avec la m?thode RenderedGridMarks.setDecimation(int, int), alors la position retourn?e sera situ?e au milieu des points ? moyenner.

Specified by:

position in class MarkIterator

Throws:

org.opengis.referencing.operation.TransformException - if a transform was required and failed.

MarkIterator.geographicArea()

amplitude

public double amplitude()

Retourne l'amplitude ? la position d'une marque. Si une d?cimation a ?t? sp?cifi?e avec la m?thode RenderedGridMarks.setDecimation(int, int), alors cette m?thode calcule la moyenne vectorielle (la moyenne des composantes x et y) aux positions des marques ? d?cimer, et retourne l'amplitude du vecteur moyen.

Overrides:

amplitude in class MarkIterator

direction

public double direction()

Retourne la direction de la valeur d'une marque. Si une d?cimation a ?t? sp?cifi?e avec la m?thode RenderedGridMarks.setDecimation(int, int), alors cette m?thode calcule la moyenne vectorielle (la moyenne des composantes x et y) aux positions des marques ? d?cimer, et retourne la direction du vecteur moyen.

Overrides:

direction in class MarkIterator

markShape

public java.awt.Shape markShape()

Retourne la forme g?om?trique servant de mod?le au tra?age des marques. Lorsque deux bandes sont utilis?es, la forme par d?faut sera une fl?che dont l'origine est ? (0,0) et qui pointe dans la direction des x positifs (soit ? un angle de 0 radians arithm?tiques).

Overrides:

markShape in class MarkIterator

See Also:

RenderedGridMarks.getMarkShape(), RenderedGridMarks.setMarkShape(java.awt.Shape)

markPaint

public java.awt.Paint markPaint()

Returns the paint for current mark.

Overrides:

markPaint in class MarkIterator

See Also:

RenderedGridMarks.getMarkPaint(), RenderedGridMarks.setMarkPaint(java.awt.Paint)

label

public java.lang.String label()

Returns the label for the current mark, or null if none.

Overrides:

label in class MarkIterator

getToolTipText

protected java.lang.String getToolTipText(GeoMouseEvent event)

Returns a tooltip text for the current mark. The default implementation returns the arrow's amplitude and direction. Note: This method is not a commited part of the API. It may moves elsewhere in a future version.

Overrides:

getToolTipText in class MarkIterator

Parameters:

event - The mouse event.

Returns:

The tool tip text for the current mark, or null if none.
