filter :: (Char -> Bool) -> ByteString -> ByteString

bytestring Data.ByteString.Char8, bytestring Data.ByteString.Lazy.Char8

O(n) filter, applied to a predicate and a ByteString, returns a ByteString containing those characters that satisfy the predicate.

filter :: (Int -> Bool) -> IntSet -> IntSet

containers Data.IntSet

O(n). Filter all elements that satisfy some predicate.

filter :: (Word8 -> Bool) -> ByteString -> ByteString

bytestring Data.ByteString.Lazy

O(n) filter, applied to a predicate and a ByteString, returns a ByteString containing those characters that satisfy the predicate.

filter :: (Word8 -> Bool) -> ByteString -> ByteString

bytestring Data.ByteString

O(n) filter, applied to a predicate and a ByteString, returns a ByteString containing those characters that satisfy the predicate. This function is subject to array fusion.

filter :: (a -> Bool) -> IntMap a -> IntMap a

containers Data.IntMap.Strict, containers Data.IntMap.Lazy

O(n). Filter all values that satisfy some predicate. > filter (> "a") (fromList [(5,"a"), (3,"b")]) == singleton 3 "b" > filter (> "x") (fromList [(5,"a"), (3,"b")]) == empty > filter (< "a") (fromList [(5,"a"), (3,"b")]) == empty

filter :: (a -> Bool) -> Map k a -> Map k a

containers Data.Map.Lazy, containers Data.Map.Strict

O(n). Filter all values that satisfy the predicate. > filter (> "a") (fromList [(5,"a"), (3,"b")]) == singleton 3 "b" > filter (> "x") (fromList [(5,"a"), (3,"b")]) == empty > filter (< "a") (fromList [(5,"a"), (3,"b")]) == empty

filter :: (a -> Bool) -> Seq a -> Seq a

containers Data.Sequence

O(n). The filter function takes a predicate p and a sequence xs and returns a sequence of those elements which satisfy the predicate.

filter :: (a -> Bool) -> Set a -> Set a

containers Data.Set

O(n). Filter all elements that satisfy the predicate.

Filtered :: CompressionStrategy

filteredStrategy :: CompressionStrategy

zlib Codec.Compression.Zlib.Internal, zlib Codec.Compression.Zlib.Raw, zlib Codec.Compression.Zlib, zlib Codec.Compression.GZip

Use the filtered compression strategy for data produced by a filter (or predictor). Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of this strategy is to force more Huffman coding and less string matching; it is somewhat intermediate between defaultCompressionStrategy and huffmanOnlyCompressionStrategy.

filterWithKey :: (Key -> a -> Bool) -> IntMap a -> IntMap a

containers Data.IntMap.Strict, containers Data.IntMap.Lazy

O(n). Filter all keys/values that satisfy some predicate. > filterWithKey (\k _ -> k > 4) (fromList [(5,"a"), (3,"b")]) == singleton 5 "a"

filterWithKey :: (k -> a -> Bool) -> Map k a -> Map k a

containers Data.Map.Lazy, containers Data.Map.Strict

O(n). Filter all keys/values that satisfy the predicate. > filterWithKey (\k _ -> k > 4) (fromList [(5,"a"), (3,"b")]) == singleton 5 "a"
