Method Detail

getPerpendicularOffset

public Expression getPerpendicularOffset()

Getter for property perpendicularOffset.

Specified by:

getPerpendicularOffset in interface LinePlacement

Returns:

Value of property perpendicularOffset.

setPerpendicularOffset

public void setPerpendicularOffset(Expression perpendicularOffset)

Setter for property perpendicularOffset.

Specified by:

setPerpendicularOffset in interface LinePlacement

Parameters:

perpendicularOffset - New value of property perpendicularOffset.

getInitialGap

public Expression getInitialGap()

Description copied from interface: LinePlacement

InitialGap specifies how far away the first graphic will be drawn relative to the start of the rendering line

Specified by:

getInitialGap in interface LinePlacement

Returns:

Expression

getGap

public Expression getGap()

Description copied from interface: LinePlacement

Gap gives the distance between two graphics.

Specified by:

getGap in interface LinePlacement

Returns:

Expression

isRepeated

public boolean isRepeated()

Description copied from interface: LinePlacement

If IsRepeated is "true", the label will be repeatedly drawn along the line with InitialGap and Gap defining the spaces at the beginning and between labels.

Specified by:

isRepeated in interface LinePlacement

Returns:

boolean

isAligned

public boolean isAligned()

Description copied from interface: LinePlacement

Labels can either be aligned to the line geometry if IsAligned is "true" (the default) or are drawn horizontally.

Specified by:

isAligned in interface LinePlacement

Returns:

boolean

isGeneralizeLine

public boolean isGeneralizeLine()

Description copied from interface: LinePlacement

GeneralizeLine allows the actual geometry, be it a linestring or polygon to be generalized for label placement. This is e.g. useful for labelling polygons inside their interior when there is need for the label to resemble the shape of the polygon.

Specified by:

isGeneralizeLine in interface LinePlacement

Returns:

boolean

accept

public Object accept(TraversingStyleVisitor visitor,
                     Object data)

Description copied from interface: LinePlacement

calls the visit method of a StyleVisitor

Specified by:

accept in interface LabelPlacement

Specified by:

accept in interface LinePlacement

Parameters:

visitor - the style visitor

accept

public void accept(StyleVisitor visitor)

Specified by:

accept in interface LabelPlacement

clone

public Object clone()

Description copied from interface: Cloneable

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object.

Specified by:

clone in interface Cloneable

Overrides:

clone in class Object

Returns:

A copy of this object.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:
