ee.Dictionary.aside

呼叫函式時,會將這個物件做為第一個引數傳遞,並傳回自身。方便,例如偵錯時:

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');

傳回相同物件,用於鏈結。

用量傳回
Dictionary.aside(func, var_args)ComputedObject
引數類型詳細資料
這個:computedobjectComputedObjectComputedObject 例項。
func函式要呼叫的函式。
var_argsVarArgs<Object>要傳遞至函式的任何額外引數。

範例

程式碼編輯器 (JavaScript)

// A dictionary (e.g. results of ee.Image.reduceRegion of an S2 image).
var dict = {
  B1: 182,
  B2: 219,
  B3: 443
};

// Print a message when constructing the ee.Dictionary.
var eeDict = ee.Dictionary(dict).aside(print, 'ee.Dictionary from an object');

}


def print_dic(dic):
