|
|
It honors both the `maxBuffer` and `encoding` options. The behavior changes slightly based on the encoding chosen: |
|
|
|
- When `encoding` is unset, it assumes an [object mode stream](https://nodesource.com/blog/understanding-object-streams/) and collects values emitted from `stream` unmodified. In this case `maxBuffer` refers to the number of items in the array (not the sum of their sizes). |
|
- When `encoding` is set to `buffer`, it collects an array of buffers. `maxBuffer` refers to the summed byte lengths of every buffer in the array. |
|
- When `encoding` is set to anything else, it collects an array of strings. `maxBuffer` refers to the summed character lengths of every string in the array. |
