Method Detail

getPerpendicularOffset

public Expression getPerpendicularOffset()

Description copied from interface: LineSymbolizer

PerpendicularOffset allows to draw lines in parallel to the original geometry. For complex line strings these parallel lines have to be constructed so that the distance between original geometry and drawn line stays equal. This construction can result in drawn lines that are actually smaller or longer than the original geometry.

The distance is in uoms and is positive to the left-hand side of the line string. Negative numbers mean right. The default offset is 0.

Specified by:

getPerpendicularOffset in interface LineSymbolizer

Returns:

Expression

setPerpendicularOffset

public void setPerpendicularOffset(Expression offset)

Description copied from interface: LineSymbolizer

Define an offset to draw lines in parallel to the original geometry.

Specified by:

setPerpendicularOffset in interface LineSymbolizer

Parameters:

offset - Distance in UOMs to offset line; left-hand side is positive; right-hand side is negative; the default value is 0

getStroke

public StrokeImpl getStroke()

Provides the graphical-symbolization parameter to use for the linear geometry.

Specified by:

getStroke in interface LineSymbolizer

Returns:

The Stroke style to use when rendering lines.

setStroke

public void setStroke(Stroke stroke)

Sets the graphical-symbolization parameter to use for the linear geometry.

Specified by:

setStroke in interface LineSymbolizer

Parameters:

stroke - The Stroke style to use when rendering lines.

accept

public Object accept(TraversingStyleVisitor visitor,
                     Object data)

Accepts a StyleVisitor to perform some operation on this LineSymbolizer.

Specified by:

accept in interface LineSymbolizer

Specified by:

accept in interface Symbolizer

Parameters:

visitor - The visitor to accept.

Returns:

value produced

accept
