# Data::Stream::Bulk::Cat(3pm)

Concatenated streams

## NAME

Data::Stream::Bulk::Cat - Concatenated streams

## VERSION

version 0.11

## SYNOPSIS

```
        use Data::Stream::Bulk::Cat;
        Data::Stream::Bulk::Cat->new(
                streams => [ $s1, $s2, $s3 ],
        );
```

## DESCRIPTION

This stream is a concatenation of several other streams.

## METHODS

- is\_done

  Returns true if the list of streams is empty.

- next

  Returns the next block from the next ready stream.

- list\_cat

  Breaks down the internal list of streams, and delegates `"list_cat"` to the first one.

  Has the effect of inlining the nested streams into the total concatenation, allowing "list\_cat" in Data::Stream::Bulk::Array to work better.
