ee.List.splice

यह फ़ंक्शन, start index से शुरू करके सूची से count एलिमेंट हटाता है. साथ ही, उस जगह पर अन्य के कॉन्टेंट को डालता है. अगर start की वैल्यू नेगेटिव है, तो यह सूची के आखिर से पीछे की ओर गिनती करता है.

उदाहरण

कोड एडिटर (JavaScript)

// An ee.List object.
var list = ee.List([0, 1, 2, 3, 4]);
print('Original list', list);

// If "other" argument is null, elements at positions specified by "start" and
// "count" are deleted. Here, the 3rd element is removed.
print('Remove 1 element', list.splice({start: 2, count: 1, other: null}));

// If "start" is negative, the position is from the end of the list.
print('Remove 2nd from last element', list.splice(-2, 1));

// Deletes 3 elements starting at position 1.
print('Remove multiple sequential elements', list.splice(1, 3));

// Insert elements from the "other" list without deleting existing elements
// by specifying the insert "start" position and setting "count" to 0.
print('Insert new elements', list.splice(2, 0, ['X', 'Y', 'Z']));

// Replace existing elements with those from the "other" list by specifying the
// "start" position to replace and the "count" of proceeding elements. If
// length of "other" list is greater than "count", the remaining "other"
// elements are inserted, they do not replace existing elements.
print('Replace elements', list.splice(2, 3, ['X', 'Y', 'Z']));
