How to use the tv4-reporter.getReporter function in tv4-reporter

assert(value: T): void {
		assert(typeOf.isJSONValue(value), 'is not a JSON value {a}', value);
		if (this.schema) {
			// validate schema
			var res: TV4SingleResult = tv4.validateResult(value, this.schema);
			if (!res.valid || res.missing.length > 0) {
				var report = reporter.getReporter(log.out.getWrite(), log.out.getStyle());
				var test = report.createTest(this.schema, value, null, res, true);
				if (res.missing.length > 0) {
					report.reportMissing(test, '   ');
					throw new Error('missing schemas');
				}
				else {
					report.reportError(test, res.error, '   ', '   ');
					throw res.error;
				}
			}
		}
	}
