mtbl_next: Iterate over mtbl file entries
In brudis-r7/mtblr: Tools to work with 'mtbl' files
Description
Usage

Details
Examples
Description
Works with mtbl_map() and mtbl_get()
Usage
1
mtbl_next(x, n = 100L)
Arguments
x
an iterator started with mtbl_map() or mtbl_get()
n
number of records to return for this iteration. It's inefficient to
sequentially iterate over large mtbl file but large values of n
are also inefficent. 100 has been an optimal value in mtbl
files used in Project Sonar. YMMV.
Details
If the number of available entries is less than n, a list
of the actual number of remaining entries is returned. Otherwise a list
of n entries is returned.
Examples

mtbl <- read_mtbl(system.file("extdata/sample.mtbl", package="mtblr"))
mp <- mtbl_map(mtbl)
(mtbl_next(mp))
mtbl_iter_close(mp)
