Methods

forZoomlevel(int zoomlevel, int level) → RenderinstructionNode

Creates a copy of itself with the data needed for the given zoomlevel. Note that this should only be called from Rendertheme and NOT from RenderthemeZoomlevel

getBoundary(RenderInfo<Renderinstruction> renderInfo) → MapRectangle

Returns the boundary of this object around the center of the area or the poi. If the boundary cannot determined exactly we need to estimate it. This method is used only if the renderinstruction adds itself to label or clash (see LayerContainer)

inherited

getType() → String

Returns the type identifier for this rendering instruction.

inherited

matchNode(LayerContainer layerContainer, NodeProperties nodeProperties) → void

Checks the nodeProperties and adds itself to the layerContainer if there is something to draw.

inherited

matchWay(LayerContainer layerContainer, WayProperties wayProperties) → void

Checks the wayProperties and adds itself to the layerContainer if there is something to draw.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

renderinstructionScale(Renderinstruction base, int zoomlevel) → void

Scales rendering parameters based on zoom level and base instruction.

inherited

secondPass(SymbolSearcher symbolSearcher) → void

Captions needs to find their assigned symbol to correctly render themself around the symbol. After all rules has been created a second pass is executed where captions are able to find their assigned symbol.

inherited

toString() → String

A string representation of this object.
