- 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).

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
