ee.Geometry.LineString.aside
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
调用一个函数,将此对象作为第一个实参传递,并返回自身。方便(例如,在调试时):
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');
返回同一对象,用于链式调用。
用法 | 返回 |
---|
LineString.aside(func, var_args) | ComputedObject |
参数 | 类型 | 详细信息 |

此:computedobject | ComputedObject | ComputedObject 实例。 |
func | 函数 | 要调用的函数。 |
var_args | VarArgs<Object> | 要传递给函数的任何额外实参。 |
