Network.Riak.JSON

Description

This module allows storage and retrieval of JSON-encoded data.

The functions in this module do not perform any conflict resolution.

Synopsis

data JSON a

plain :: JSON a -> a
get :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> R -> IO (Maybe ([c], VClock))
getMany :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> [Key] -> R -> IO [Maybe ([c], VClock)]
put :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> Maybe VClock -> c -> W -> DW -> IO ([c], VClock)
putIndexed :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> [IndexValue] -> Maybe VClock -> c -> W -> DW -> IO ([c], VClock)

json :: a -> JSON a Source #

Wrap up a value so that it will be encoded and decoded as JSON when converted to/from Content.

plain :: JSON a -> a Source #

Unwrap a JSON-wrapped value.

get :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> R -> IO (Maybe ([c], VClock)) Source #

Retrieve a value. This may return multiple conflicting siblings. Choosing among them is your responsibility.

getMany :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> [Key] -> R -> IO [Maybe ([c], VClock)] Source #

put :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> Maybe VClock -> c -> W -> DW -> IO ([c], VClock) Source #

Store a single value. This may return multiple conflicting siblings. Choosing among them, and storing a new value, is your responsibility.

You should only supply Nothing as a VClock if you are sure that the given type+bucket+key combination does not already exist. If you omit a VClock but the type+bucket+key does exist, your value will not be stored.

putIndexed :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> [IndexValue] -> Maybe VClock -> c -> W -> DW -> IO ([c], VClock) Source #

Store a single value indexed.

put_ :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> Key -> Maybe VClock -> c -> W -> DW -> IO () Source #

Store a single value, without the possibility of conflict resolution.

You should only supply Nothing as a VClock if you are sure that the given type+bucket+key combination does not already exist. If you omit a VClock but the type+bucket+key does exist, your value will not be stored, and you will not be notified.

putMany :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> [(Key, Maybe VClock, c)] -> W -> DW -> IO [([c], VClock)] Source #

Store many values. This may return multiple conflicting siblings for each value stored. Choosing among them, and storing a new value in each case, is your responsibility.

You should only supply Nothing as a VClock if you are sure that the given type+bucket+key combination does not already exist. If you omit a VClock but the type+bucket+key does exist, your value will not be stored.

putMany_ :: (FromJSON c, ToJSON c) => Connection -> Maybe BucketType -> Bucket -> [(Key, Maybe VClock, c)] -> W -> DW -> IO () Source #

Store many values, without the possibility of conflict resolution.

You should only supply Nothing as a VClock if you are sure that the given type+bucket+key combination does not already exist. If you omit a VClock but the type+bucket+key does exist, your value will not be stored, and you will not be notified.
