ee.Date.aside
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 |
---|
Date.aside(func, var_args) | ComputedObject |
Argument | Type | Details |
---|
this: computedobject | ComputedObject | The ComputedObject instance. |
func | Function | The function to call. |
var_args | VarArgs | Any extra arguments to pass to the function. |
Examples
// Print a message when constructing the ee.Date.
var eeDict = ee.Date(Date.now()).aside(print, "Today's date (UTC)");
Python setup
See the
Python Environment page for information on the Python API and using
geemap
for interactive development.
import ee
import geemap.core as geemap
from datetime import datetime
def print_date(ee_date, message):
"""Prints a formatted date, along with a descriptive message."""
display(message, ee_date.format("YYYY-mm-dd"))
# Print a message when constructing the ee.Date.
ee_date = ee.Date(datetime.now()).aside(print_date, "Today's date (UTC):")
