Method Detail

Copies the object.

Overrides:: copy in class IlvSimpleLink

Returns:: A copy of this IlvGraphic instance.

public int getMode()

getQualityLevel()

getQualityLevel

public static int getQualityLevel()

Returns the current quality level.

Returns:: current quality level
See Also:: setQualityLevel(int)

setOptimized

public void setOptimized(boolean optimized)

Sets or clears the "optimized" mode of this link. Optimized mode offers better performances in many situations:

The computation of the link's bounding box is faster if the link's shape is a polygon (that is, if the wave mode is not used, and if the link is not curved).
Painting the link is faster if the link's mode is MODE_UNICOLOR, or if the link is very thin (link width less than 2 pixels after applying the view's transformer). Painting is not optimized in any of these cases:
- the link uses borders,
- the link uses a non-default crossing mode,
- wave mode is used,
- the link is curved or has a non-zero radius,
- the arrow mode is ARROW_GRADIENT.

Optimized mode is on by default.

In optimized mode, the actual look of the link may be slightly different in some cases, especially for think links. If you need the links to look exactly the same as with JViews 6.0, you can turn optimized mode off.

Parameters:: optimized - If true, the code optimizations are used, otherwise the behavior is the same as in JViews 6.0.
Since:: JViews 6.5
See Also:: setWave(String), setCurved(float), setMode(int), setArrowMode(int), setBorderWidth(float), setCrossingMode(int)

isOptimized

public boolean isOptimized()

Returns the "optimized" mode of this link.

Returns:: true if mode is optimized
Since:: JViews 6.5
See Also:: setOptimized(boolean)

setAlternateColor
