  - 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 thick 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.

  - setAlternateColor
```
public void setAlternateColor(Color c)
```
    Sets the alternating color. If not null is passed, the link alternates foreground color with this color value. The lineStyle property controls alternate color dashes. If lineStyle is null, alternate segments are proportional to lineWidth. This property supports IlvBlinkingColor. The method fires events when this property changes.
    Warning: when the general link is in optimized mode (i.e setOptimized(boolean) is call with true parameter), the alternating color can be ignored, depending on other properties of the object.
    
    Parameters:
    
    c - The new color.

```
    Sets how the decoration is displayed. A bit set parameter is used, composed of the masks shown.
    Parameters:
    
    index - The position of the decoration to display.
    value - A bit set, composed of the following masks:
    
    DECORATION_FIXED_SIZE: If set, the decoration is not zoomable.
    DECORATION_ROTATE: If set, the decoration rotates along the link shape. The behavior of the rotation angle depends on the options DECORATION_PROPORTIONAL_ANGLE and DECORATION_RIGHT_SIDE_UP_ANGLE. If none of the two angle options is set, the decoration uses rightside up angles when the option DECORATION_OVER is not set, and uses proportional angles when the option DECORATION_OVER is set. If one of the angle options is set, the decoration uses the angle as specified in that option.
    DECORATION_PROPORTIONAL_ANGLE: If set in combination with DECORATION_ROTATE, the rotation angle is directly propertional to the slope of the link. This is useful for decorations such as icons or arrowheads that must follow the slope of the link. If the DECORATION_ROTATE option is not set, this option has no effect.
    DECORATION_RIGHT_SIDE_UP_ANGLE: If set in combination with DECORATION_ROTATE, the rotation angle keeps the decoration rightside up. This is useful for decorations such as labels that should not become upside down when being rotated ca 180 degree. If the DECORATION_ROTATE option is not set, this option has no effect.
    DECORATION_ANIMATE: If set, and if the animateSpeed property is not zero, the decoration is animated.
    DECORATION_OVER: The decoration is over the link center.
    DECORATION_ANCHOR_[LEFT|RIGHT|TOP|BOTTOM]: Sets the corner of the decoration to be at the middle of the link (works only together with DECORATION_OVER).
    DECORATION_NOTHING: Means default values (zoomable, no rotation, no animation). This option should not be combined with any other option.
    DECORATION_ABSOLUTE: The link no longer changes decoration position.
    DECORATION_FULL_RETRACT_AT_END: When arrow mode is ARROW_DECORATION, the link stops at the decoration bounding box (which acts as the arrow).
    DECORATION_HALF_RETRACT_AT_END: When arrow mode is ARROW_DECORATION, the link stops at the middle of the decoration bounding box (which acts as the arrow).
    DECORATION_NO_RETRACT_AT_END: When arrow mode is ARROW_DECORATION, the link does not stop at the decoration bounding box (which acts as the arrow).

```
public void setBaseTextDirection(int baseTextDirection)
```
    Changes the base direction of the text. The possible choices are:
    - IlvBidiUtil.INHERITED_DIRECTION: the base text direction is inherited from the graphic bag that contains this object. If this object is not contained in a graphic bag, the base text direction is calculated from the component orientation.
    - IlvBidiUtil.COMPONENT_DIRECTION: the base text direction is calculated from the component orientation.
    - IlvBidiUtil.LEFT_TO_RIGHT: the base text direction is left-to-right.
    - IlvBidiUtil.RIGHT_TO_LEFT: the base text direction is right-to-left.
    - IlvBidiUtil.CONTEXTUAL_DIRECTION: the base test direction is determined from the text that is displayed according to the standard Bidi algorithm, if the text contains at least one character with a strong left-to-right or right-to-left direction. If the text doesn't contain any character with a strong direction, the real text direction is determined from the current component orientation of the object.

  - getResolvedBaseTextDirection
```
public int getResolvedBaseTextDirection()
```
    Returns the resolved base text direction.
    This method is similar to getBaseTextDirection() but determines the value when it is inherited from a parent component (IlvBidiUtil.INHERITED_DIRECTION) or dependent on the component orientation (IlvBidiUtil.COMPONENT_DIRECTION). Hence, there are only 3 possible return values:
    - IlvBidiUtil.LEFT_TO_RIGHT: the base text direction is left-to-right.
    - IlvBidiUtil.RIGHT_TO_LEFT: the base text direction is right-to-left.
    - IlvBidiUtil.CONTEXTUAL_DIRECTION: the base test direction is determined from the text that is displayed according to the standard Bidi algorithm, if the text contains at least one character with a strong left-to-right or right-to-left direction. If the text doesn't contain any character with a strong direction, the real text direction is determined from the current component orientation of the object.

```
public void setCurved(double value)
```
    Sets the curved look and the smoothness of the spline. The value range is between 0.0 (sharp bends) and 1.0 (smooth bends). A recommended value is 0.65.
    The default value is 0.0, that is, no curve at all. The method fires events when this property changes.
    Changing the smoothness influences the bounding box of the object. Therefore it should be only done using an IlvApplyObject passed to IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean).
    
    Parameters:

    Sets the margin on the border of all instances of IlvGeneralLink to be used for contains(ilog.views.IlvPoint, ilog.views.IlvPoint, ilog.views.IlvTransformer). The method contains(ilog.views.IlvPoint, ilog.views.IlvPoint, ilog.views.IlvTransformer) returns true if the test point is within the line shape of the link plus this margin. Enlarging this margin has the effect that selecting the link with small line width is easier possible when clicking near the line of the link instead of exactly on the link. The margin is also obeyed when testing if the point is within a link decoration. The default margin is 1.

  - setAnimateSpeed
```
public void setAnimateSpeed(float speed)
```
    Sets the speed of animation. Actually, the refresh speed is controlled by the variable ANIM_SPEED. This method controls only the threshold, that is, the part of the link reached at each refresh speed. For example, a value of 0.1 moves a tenth of the link length. 0.9 moves nine tenths of the link length. (This is the same effect as one tenth backward.)
    This method calls IlvGraphic.setBlinkingAction(ilog.views.java2d.IlvBlinkingAction) to set a blinking action on the link to implement the animation.
    
    Note that animation works for dashes, alternate colors, and decorations. For decorations, the ratio is computed against the whole link length. For dashes and alternate colors, the line style period is used.
    
    The method fires events when this property changes.
    
    Parameters:
    
    speed - The new speed, between 0 and 1. 0 stops the animation.
