writeLinesWith

writeLinesWith(Array<String>, String): Binary

Writes the specified lines and returns the binary content.

Introduced in DataWeave 2.2.0. Supported by Mule 4.2 and later.

Parameters

Name Description

Name	Description
`content`	Array of items to write.
`charset`	String representing the encoding to use when writing.

content

Array of items to write.

charset

String representing the encoding to use when writing.

Example

This example inserts a new line (\n) after each iteration. Specifically, it uses map to iterate over the result of to(1, 10), [1,2,3,4,5], then writes the specified content ("Line $"), which includes the unnamed variable $ for each number in the array.

Note that without writeLinesWith "UTF-8", the expression { lines: to(1, 10) map "Line $" } simply returns an array of line numbers as the value of an object: { "lines": [ "line 1", "line 2", "line 3", "line 4", "line 5" ] }.

Source

{ lines: to(1, 10) map "Line $" writeLinesWith  "UTF-8" }

Output

{
  "lines": "Line 1\nLine 2\nLine 3\nLine 4\nLine 5\n"
}
