Layer

This class is not needed by ordinary S2Builder clients. It is only necessary if you wish to implement a new S2Builder::Layer subtype.

abstract

class Layer {

alias EdgeType = S2Builder.EdgeType;

alias GraphOptions = .GraphOptions;

alias Graph = .Graph;

alias Label = S2Builder.Label;

alias LabelSetId = S2Builder.LabelSetId;

GraphOptions graphOptions();

void build(Graph g, S2Error error);

}

Functions

build void build(Graph g, S2Error error): Assembles a graph of snapped edges into the geometry type implemented by this layer. If an error is encountered, sets "error" appropriately.
graphOptions GraphOptions graphOptions(): Defines options for building the edge graph that is passed to Build().
