Data::Stream::Bulk::Filter(3pm) User Contributed Perl Documentation Data::Stream::Bulk::Filter(3pm)NAME
Data::Stream::Bulk::Filter - Streamed filtering (block oriented)
VERSION
version 0.11
SYNOPSIS
use Data::Stream::Bulk::Filter;
Data::Stream::Bulk::Filter->new(
filter => sub { ... },
stream => $stream,
);
DESCRIPTION
This class implements filtering of streams.
ATTRIBUTES
filter
The code reference to apply to each block.
The block is passed to the filter both in $_ and as the first argument.
The return value should be an array reference. If no true value is returned the output stream does not end, but instead an empty block
is substituted (the parent stream controls when the stream is depleted).
stream
The stream to be filtered
METHODS
is_done
loaded
Delegated to "stream"
next
Calls "next" on "stream" and applies "filter" if a block was returned.

Data::Stream::Bulk::Array(3pm) User Contributed Perl Documentation Data::Stream::Bulk::Array(3pm)NAME
Data::Stream::Bulk::Array - Data::Stream::Bulk wrapper for simple arrays.
VERSION
version 0.11
SYNOPSIS
return Data::Stream::Bulk::Array->new(
array => @results,
);
DESCRIPTION
This implementation of the Data::Stream::Bulk api wraps an array.
The use case is to keep the consumer of the data set implementation agnostic so that it can deal with larger data sets if they are
encountered, but still retain most of the simplicity when the current data set easily fits in memory.
ATTRIBUTES
array
The array reference to wrap.
METHODS
next
Returns the array reference on the first invocation, and nothing thereafter.
is_done
Returns true if "next" has been called.
list_cat
Squishes adjacent arrays into a new array.
filter $filter
Immediately applies $filter to the internal array and returns $self.
loaded
Returns true
