How does one handle type casting in TypeScript or Javascript?
Say I have the following TypeScript code:
module Symbology {
export class SymbolFactory {
createStyle( symbolInfo : SymbolInfo) : any {
if (symbolInfo == null)
{
return null;
}
if (symbolInfo.symbolShapeType === "marker") {
// how to cast to MarkerSymbolInfo
return this.createMarkerStyle((MarkerSymbolInfo) symbolInfo);
}
}
createMarkerStyle(markerSymbol : MarkerSymbolInfo ): any {
throw "createMarkerStyle not implemented";
}
}
}
where SymbolInfo is a base class. How do I handle typecasting from SymbolInfo to MarkerSymbolInfo in TypeScript or Javascript?
