ee.Dictionary.aside
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
이 객체를 첫 번째 인수로 전달하고 자체를 반환하는 함수를 호출합니다. 디버깅 시 편리합니다.
var c = ee.ImageCollection('foo').aside(print)
.filterDate('2001-01-01', '2002-01-01').aside(print, 'In 2001')
.filterBounds(geom).aside(print, 'In region')
.aside(Map.addLayer, {min: 0, max: 142}, 'Filtered')
.select('a', 'b');
연결을 위해 동일한 객체를 반환합니다.
사용 | 반환 값 |
---|
Dictionary.aside(func, var_args) | ComputedObject |
인수 | 유형 | 세부정보 |
---|
다음과 같은 경우: computedobject | ComputedObject | ComputedObject 인스턴스입니다. |
func | 함수 | 호출할 함수입니다. |
var_args | VarArgs<Object> | 함수에 전달할 추가 인수입니다. |
