ee.String.split

Dzieli ciąg znaków na podstawie wyrażenia regularnego i zwraca listę ciągów znaków.

Wykorzystanie	Zwroty
String.split(regex, flags)	Lista

Argument	Typ	Szczegóły
to: string	Ciąg znaków	Ciąg do podzielenia.
regex	Ciąg znaków	Wyrażenie regularne, według którego ma nastąpić podział. Jeśli wyrażenie regularne jest pustym ciągiem znaków, ciąg wejściowy jest dzielony na poszczególne znaki.
flags	Ciąg tekstowy, domyślnie: ""	Ciąg znaków określający flagę wyrażenia regularnego: „i” (ignorowanie wielkości liter).

Przykłady

Edytor kodu (JavaScript)

var s = ee.String('aBAbcD');
print(s.split('Ab')); // ["aB","cD"]
// 'i' tells split to ignore case.
print(s.split('ab', 'i')); // ["","","cD"]
// Split on 'b' or 'c'
print(s.split('[bc]', 'i')); // ["a","A","","D"]
// Split on 'BA' or 'c'
print(s.split('(BA|c)')); // ["a","b","D"]

var s = ee.String('a,b,cdee f,g');
// ["a",",","b",",","c","d","e","e"," ","f",",","g"]
print(s.split(''));

print(s.split(' ')); // ["a,b,cdee","f,g"]
print(s.split('[[:space:]]')); // ["a,b,cdee","f,g"]

print(s.split(',')); // ["a","b","cdee f","g"]

print(s.split('ee')); // ["a,b,cd"," f,g"]

// Split on any lower case letter.
print(s.split('[a-z]')); // ["",",",",","","",""," ",","]

// ^ as the first character in [] excludes.
print(s.split('[^a-z]')); // ["a","b","cdee","f","g"]

// Splitting on characters that are special to split.
var s = ee.String('a.b*c?d');
print(s.split('\\.')); // ["a","b*c?d"]
print(s.split('[*]')); // ["a.b","c?d"]
print(s.split('[?]')); // ["a.b*c","d"]
