pull-merge v1.0.4
pull-merge
merge sorted pull-streams into one pull stream, while maintaining back-pressure. Source pull streams MUST be in order.
example
var pull = require('pull-stream')
var merge = require('pull-merge')
pull(
merge(pull.values([1, 5, 6]), pull.values([2, 4, 7])),
pull.collect(function (err, ary) {
if(err) throw err
console.log(ary)
//=> [1, 2, 4, 5, 6, 7]
})
)
signatures
merge(left, right, compare?)
return a stream that is the merge of left and right streams.
merge pulls a chunk from both left
and right
and then
compares them. compare
has the same signature as Array#sort(compare)
.
If the two chunks are compared the same, the chunk from the right stream
is taken, but the left chunk is dropped.
Otherwise, the lowest chunk is passed to the stream.
merge(streams..., compare?)
Merge a collection of steams. This calls the first signature recursively.
