public BoundingXYVisitor()

Method Detail

visit

public void visit(Node n)

Description copied from interface: OsmPrimitiveVisitor

Visiting call for points.

Specified by:

visit in interface OsmPrimitiveVisitor

Parameters:

n - The node to inspect.

visit

public void visit(Way w)

Description copied from interface: OsmPrimitiveVisitor

Visiting call for lines.

Specified by:

visit in interface OsmPrimitiveVisitor

Parameters:

w - The way to inspect.

visit

public void visit(Relation r)

Description copied from interface: OsmPrimitiveVisitor

Visiting call for relations.

Specified by:

visit in interface OsmPrimitiveVisitor

Parameters:

r - The relation to inspect.

visit

public void visit(INode n)

Description copied from interface: PrimitiveVisitor

Visiting call for nodes.

Specified by:

visit in interface PrimitiveVisitor

Parameters:

n - The node to inspect.

visit

public void visit(IWay<?> w)

Description copied from interface: PrimitiveVisitor

Visiting call for ways.

Specified by:

visit in interface PrimitiveVisitor

Parameters:

w - The way to inspect.

visit

public void visit(IRelation<?> r)

Description copied from interface: PrimitiveVisitor

Visiting call for relations.

Specified by:

visit in interface PrimitiveVisitor

Parameters:

r - The relation to inspect.

visit

public void visit(Bounds b)

Visiting call for bounds.

Parameters:

b - bounds

visit

public void visit(ProjectionBounds b)

Visiting call for projection bounds.

Parameters:

b - projection bounds

visit

public void visit(ILatLon latlon)

Visiting call for lat/lon.

Parameters:

latlon - lat/lon

Since:

12725 (public for ILatLon parameter)

visit

public void visit(LatLon latlon)

Visiting call for lat/lon.

Parameters:

latlon - lat/lon

visit

public void visit(EastNorth eastNorth)

Visiting call for east/north.

Parameters:

eastNorth - east/north

hasExtend

public boolean hasExtend()

Determines if the visitor has a non null bounds area.

Returns:

true if the visitor has a non null bounds area

See Also:

ProjectionBounds.hasExtend()

getBounds

public ProjectionBounds getBounds()

Returns:

The bounding box or null if no coordinates have passed

enlargeBoundingBox

public void enlargeBoundingBox()

Enlarges the calculated bounding box by 0.0002 degrees or user value given in edit.zoom-enlarge-bbox. If the bounding box has not been set (min or max equal null) this method does not do anything.

enlargeBoundingBox

public void enlargeBoundingBox(double enlargeDegreeX,
                               double enlargeDegreeY)

Enlarges the calculated bounding box by the specified number of degrees. If the bounding box has not been set (min or max equal null) this method does not do anything.

Parameters:

enlargeDegreeX - number of degrees to enlarge on each side along X

enlargeDegreeY - number of degrees to enlarge on each side along Y

enlargeBoundingBoxLogarithmically

public void enlargeBoundingBoxLogarithmically()

Enlarges the bounding box up to 0.0002 degrees, depending on its size and user settings in edit.zoom-enlarge-bbox. If the bounding box is small, it will be enlarged more in relation to its beginning size. The larger the bounding box, the smaller the change, down to 0.0 degrees. If the bounding box has not been set (min or max equal null) this method does not do anything.

Since:

14628

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

computeBoundingBox

public void computeBoundingBox(java.util.Collection<? extends IPrimitive> primitives)

Compute the bounding box of a collection of primitives.

Parameters:

primitives - the collection of primitives
