SourceListMap.prototype.prepend(generatedCode: string)SourceListMap.prototype.prepend(generatedCode: string,source: string,originalSource: string)SourceListMap.prototype.prepend(sourceListMap: SourceListMap)Prepend some stuff.
Get generated code.
SourceListMap.prototype.toStringWithSourceMap(options: object)Get generated code and SourceMap. options can contains file property which defines the file property of the SourceMap.
SourceListMap.prototype.mapGeneratedCode(fn: function) : SourceListMapApplies fn to each generated code block (per line). The returned value is set as new generated code. Returns a new SourceListMap.
Removing and adding lines is supported. The SourceMap complexity will increase when doing this.
