split

fun CharSequence.split(regex: Pattern, limit: Int = 0): List<String>(source)

Splits this char sequence around matches of the given regular expression.

This function has two notable differences from the method Pattern.split:

  • the function returns the result as a List<String> rather than an Array<String>;

  • when the limit is not specified or specified as 0, this function doesn't drop trailing empty strings from the result.

Parameters

limit

Non-negative value specifying the maximum number of substrings to return. Zero by default means no limit is set.

fun CharSequence.split(vararg delimiters: String, ignoreCase: Boolean = false, limit: Int = 0): List<String>(source)

Splits this char sequence to a list of strings around occurrences of the specified delimiters.

1.0

Parameters

delimiters

One or more strings to be used as delimiters.

ignoreCase

true to ignore character case when matching a delimiter. By default false.

limit

The maximum number of substrings to return. Zero by default means no limit is set.

To avoid ambiguous results when strings in delimiters have characters in common, this method proceeds from the beginning to the end of this string, and matches at each position the first element in delimiters that is equal to a delimiter in this instance at that position.
