Method Summary

Modifier and Type	Method	Description
Object	accept(TraversingStyleVisitor visitor, Object extraData)	calls the visit method of a StyleVisitor
AnchorPoint	getAnchorPoint()	Returns the AnchorPoint which identifies the location inside a textlabel to use as an "anchor" for positioning it relative to a point geometry.
Displacement	getDisplacement()	Returns the Displacement which gives X and Y offset displacements to use for rendering a text label near a point.
Expression	getRotation()	Returns the rotation of the label.
void	setAnchorPoint(AnchorPoint anchorPoint)	sets the AnchorPoint which identifies the location inside a textlabel to use as an "anchor" for positioning it relative to a point geometry.
void	setDisplacement(Displacement displacement)	sets the Displacement which gives X and Y offset displacements to use for rendering a text label near a point.
void	setRotation(Expression rotation)	sets the rotation of the label.

Method Detail

getAnchorPoint

AnchorPoint getAnchorPoint()

Returns the AnchorPoint which identifies the location inside a textlabel to use as an "anchor" for positioning it relative to a point geometry.

Returns:

anchorPoint from the relative to the original geometry

setAnchorPoint

void setAnchorPoint(AnchorPoint anchorPoint)

sets the AnchorPoint which identifies the location inside a textlabel to use as an "anchor" for positioning it relative to a point geometry.

Parameters:

anchorPoint - relative to the original geometry

getDisplacement

Displacement getDisplacement()

Returns the Displacement which gives X and Y offset displacements to use for rendering a text label near a point.

Returns:

Offset to use when rendering text near a point

setDisplacement

void setDisplacement(Displacement displacement)

sets the Displacement which gives X and Y offset displacements to use for rendering a text label near a point.

getRotation

Expression getRotation()

Returns the rotation of the label.

Returns:

rotation of the label as a dynamic expression

accept

Object accept(TraversingStyleVisitor visitor,
              Object extraData)

calls the visit method of a StyleVisitor

Specified by:

accept in interface LabelPlacement

Parameters:

visitor - the style visitor

setRotation

void setRotation(Expression rotation)

sets the rotation of the label.

Sets the rotation of the label.
