mps.cache.DataCache

Represent cache concept in MATLAB code

Starting in a future release, Redis™ will no longer ship with MATLAB^® Production Server™ and MATLAB Compiler SDK™. Redis supports the data persistence functionality in these products. Provide your own Redis persistence service instead. Affected functions include start, stop, and restart.

Description

mps.cache.DataCache represents the concept of cache in MATLAB code. It is an abstract class that serves as a superclass for each persistence provider-specific data cache class.

Currently, Redis and MATLAB are the only supported persistence providers. Therefore, the cache objects will be of type mps.cache.RedisCache or mps.cache.MATFileCache.

Creation

Create a persistence provider-specific subclass of mps.cache.DataCache using mps.cache.connect.

Properties

See provider-specific subclasses for properties.

Object Functions

`mps.cache.connect`	Connect to cache, or create a cache if it doesn't exist
`bytes`	Return the number of bytes of storage used by value stored at each key
`clear`	Remove all keys and values from cache
`flush`	Write all locally modified keys to the persistence service
`get`	Fetch values of keys from cache
`getp`	Get the value of a public cache property
`isKey`	Determine if the cache contains specified keys
`keys`	Get all keys from cache
`length`	Number of key-value pairs in the data cache
`purge`	Flush all local data to the persistence service
`put`	Write key-value pairs to cache
`remove`	Remove keys from cache
`retain`	Store remote keys from cache locally or return locally stored keys

Examples

Connect to a Redis Cache

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')

c = 

RedisCache with properties:

          Host: 'localhost'
          Port: 4519
          Name: 'myCache'
    Operations: "read | write | create | update"
     LocalKeys: {}
    Connection: 'myRedisConnection'

Use getp instead of dot notation to access properties.
