    java.lang.Object
      org.biojava.bio.gui.glyph.ArrowGlyph

All Implemented Interfaces:
  Glyph

    public class ArrowGlyph

extends Object
implements Glyph

A Glyph that paints an arrow shape within the bounds. The `setDirection` method allows the decision of the direction, to which the arrow points.

Since:
  1.5
Author:
  Mark Southern, Andreas Dräger

Constructor Summary
`ArrowGlyph()` Creates a new `ArrowGlyph`, which is filled with the color blue by default.
`ArrowGlyph(Paint fillPaint, Paint outerPaint)` Creates a new `ArrowGlyph`, which is filled with the given color.
`ArrowGlyph(Rectangle2D.Float bounds)` This constructs an arrow in the given bounds, which is colored blue.
`ArrowGlyph(Rectangle2D.Float bounds, Paint fillPaint, Paint outerPaint)` Constructor which sets both the size of this arrow and its color.

Method Summary
`Rectangle2D.Float` | `getBounds()`
`Paint` | `getFillPaint()` Returns the paint properties of this glyph.
`Paint` | `getOuterPaint()` Returns the paint properties of the outer line of this glyph.
`void` | `render(Graphics2D g)`
`void` | `setBounds(Rectangle2D.Float r)`
`void` | `setDirection(int direction)` This method allows you to decide in which direction the arrow has to point.
`void` | `setFillPaint(Paint fillPaint)` Allows you to set the paint properties of this glyph.
`void` | `setOuterPaint(Paint outerPaint)` Allows setting the paint properties of the outer line of this glyph to the given value.

Constructor Detail

### ArrowGlyph

    public ArrowGlyph()

  Parameters:
    `fillPaint` - Paint properties to fill this arrow.
    `outerPaint` - Paint properties of the outer border of this arrow.

### ArrowGlyph

    public ArrowGlyph(Rectangle2D.Float bounds)

  This constructs an arrow in the given bounds, which is colored blue.

  Parameters:
    `bounds` -

### ArrowGlyph

    public ArrowGlyph(Rectangle2D.Float bounds,
                      Paint fillPaint,
                      Paint outerPaint)

    `bounds` -
    `fillPaint` -

Method Detail

### getBounds

    public Rectangle2D.Float getBounds()

  Specified by:
    `getBounds` in interface `Glyph`

### setBounds

    public void setBounds(Rectangle2D.Float r)

  Specified by:
    `setBounds` in interface `Glyph`

### setDirection

    public void setDirection(int direction)

  This method allows you to decide in which direction the arrow has to point. The definition of directions is equal to the definition of `StrandedFeature`.

  Parameters:
    `direction` - A +1 means to the right, -1 to the left an 0 (and any other value) produces a rectangular shape without arrows at its end.

### render

    public void render(Graphics2D g)

  Specified by:
    `render` in interface `Glyph`

### getFillPaint

    public Paint getFillPaint()

  Returns the paint properties of this glyph.

  Returns:
    the fillPaint

### setFillPaint

    public void setFillPaint(Paint fillPaint)

  Allows you to set the paint properties of this glyph.

  Parameters:
    `fillPaint` -

### getOuterPaint

    public Paint getOuterPaint()

  Returns the paint properties of the outer line of this glyph.

  Returns:

### setOuterPaint

    public void setOuterPaint(Paint outerPaint)

  Allows setting the paint properties of the outer line of this glyph to the given value.

  Parameters:
    `outerPaint` -
