ee.Dictionary.aside

Page Summary

• The aside method calls a function with the current object as the first argument and returns the same object, enabling method chaining.

• The aside method is useful for debugging by allowing you to inspect the object's state at different points in a chain of operations.

• The aside method accepts the function to be called as the first argument and any additional arguments to pass to that function.

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.

Usage	Returns
Dictionary.aside(func, var_args)	ComputedObject

Argument	Type	Details
this: computedobject	ComputedObject	The ComputedObject instance.
func	Function	The function to call.
var_args	VarArgs[Object]	Any extra arguments to pass to the function.

Examples

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

# Print a message when constructing the ee.Dictionary.
