Fetch values of keys from cache

Description

example

values= get(c,keys)fetches values of keys specified bykeysfrom the cache specified byc. Values are returned in the same order as input variables as a cell array.

Examples

Start a persistence service that uses Redis™ as the persistence provider. The service requires a connection name and an open port. Once the service is running, you can connect to the service using the connection name and create a cache.

ctrl = mps.cache.control('myRedisConnection','Redis','Port',4519); start(ctrl) c = mps.cache.connect('myCache','Connection','myRedisConnection');

Add keys and values to the cache.

put(c,'keyOne',10,'keyTwo',20,'keyThree',30,'keyFour',[400 500],'keyFive',magic(5))

Get all the keys and associated values and display them as a MATLAB®table.

k = keys(c) v = get(c,{'keyOne','keyTwo','keyThree','keyFour','keyFive'}) tt = table(keys(c), get(c,keys(c))','VariableNames',{'Keys','Values'})
k = 5×1 cell array {'keyFive' } {'keyFour' } {'keyOne' } {'keyThree'} {'keyTwo' } v = 1×5 cell array {[10]} {[20]} {[30]} {1×2 double} {5×5 double} tt = 5×2 table Keys Values __________ ____________ 'keyFive' [5×5 double] 'keyFour' [1×2 double] 'keyOne' [ 10] 'keyThree' [ 30] 'keyTwo' [ 20]

Input Arguments

collapse all

A data cache represented by a persistence provider specific data cache object.

Currently, Redis and MATLAB are the only supported persistence providers. Therefore, the cache objects will be of typemps.cache.RedisCacheormps.cache.MATFileCache.

Example:c

A cell array of keys whose values you want to retrieve from cache.

Example:{‘keyOne’,‘keyTwo’,‘keyThree’,'keyFour','keyFive'}

Output Arguments

collapse all

A list of values associated with keys, returned as a cell array.
