trim
trim(input: String) : String
Returns input with all leading and trailing whitespace removed, including the space, tab, newline, form feed, and
carriage return characters. Whitespace between other characters is left in place. For example, trim(" hello ") is
"hello".
Examples:
trim(" hello ")returns"hello"trim("no padding")returns"no padding"trim(" ")returns""(empty string, because the input is all whitespace)trim(" hello world ")returns"hello world"(because only leading & trailing space is removed)
Null input
trim terminates the query with an error when input is null. Guard against null values with an isPresent()
condition first.
