ee.Dictionary.aside

Stay organized with collections Save and categorize content based on your preferences.

Calls a function passing this object as the first argument, and returning itself. Convenient e.g. when debugging:

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');

Returns the same object, for chaining.

// 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');

Colab (Python)

# A dictionary (e.g. results of ee.Image.reduceRegion of an S2 image).
dic = {
    'B1': 182,
    'B2': 219,
    'B3': 443
}


def print_dic(dic):
  """Prints the dictionary."""
  print('ee.Dictionary from client-side dictionary:', dic.getInfo())

# Print a message when constructing the ee.Dictionary.
ee_dic = ee.Dictionary(dic).aside(print_dic)
