示例1: findMarker
private findMarker(pos: IPosition, findOnSameLine: boolean): IMarker {
if (this.lastMarker && Range.containsPosition(this.lastMarker, pos)) {
return this.lastMarker;
}
var markers = this.getMarkers(); // makers sorted by line start number
var result: IMarker = null;
var bestDistance: number = 0;
var lineNumber = pos.lineNumber;
// find first marker with a line number greater equal the current position
var idx = arrays.findFirst(markers, m => m.startLineNumber >= lineNumber);
while (idx < markers.length && markers[idx].startLineNumber === lineNumber) {
var marker = markers[idx];
if (marker.startColumn <= pos.column && marker.endColumn >= pos.column) {
return marker;
}
if (findOnSameLine) {
var dist = pos.column < marker.startColumn ? marker.startColumn - pos.column : pos.column - marker.endColumn;
if (!result || dist < bestDistance) {
result = marker;
bestDistance = dist;
}
}
idx++;
}
return result;
