Class Caches

java.lang.Object

com.okta.sdk.cache.Caches

public class Caches
extends Object

Static utility/helper factory methods for building CacheManagers and their associated cache regions, suitable for SINGLE-JVM APPLICATIONS.

If your application is deployed on multiple JVMs (e.g. a distributed/clustered web app), you might not want to use the builders here and instead implement the CacheManager API directly to use your distributed/clustered cache technology of choice.

See the CacheManagerBuilder JavaDoc for more information the effects of caching in single-jvm vs distributed-jvm applications.

Usage Example

 import static com.okta.sdk.cache.Caches.*;

 ...

 Caches.newCacheManager()
     .withDefaultTimeToLive(1, TimeUnit.DAYS) //general default
     .withDefaultTimeToIdle(2, TimeUnit.HOURS) //general default
     .withCache(forResource(Account.class) //Account-specific cache settings
         .withTimeToLive(1, TimeUnit.HOURS)
         .withTimeToIdle(30, TimeUnit.MINUTES))
     .withCache(forResource(Group.class) //Group-specific cache settings
         .withTimeToLive(2, TimeUnit.HOURS))

     // ... etc ...

     .build(); //build the CacheManager
 

The above TTL and TTI times are just examples showing API usage - the times themselves are not recommendations. Choose TTL and TTI times based on your application requirements.

Method Detail

newCacheManager

public static CacheManagerBuilder newCacheManager()

Instantiates a new CacheManagerBuilder suitable for SINGLE-JVM APPLICATIONS. If your application is deployed on multiple JVMs (e.g. for a distributed/clustered web app), you might not want to use this method and instead implement the CacheManager API directly to use your distributed/clustered cache technology of choice.

See the CacheManagerBuilder JavaDoc for more information the effects of caching in single-jvm vs distributed-jvm applications.

Returns:

a new CacheManagerBuilder suitable for SINGLE-JVM APPLICATIONS.

newDisabledCacheManager

public static CacheManager newDisabledCacheManager()

Instantiates a new CacheManager that disables caching entirely. While production applications will usually enable a working CacheManager, you might configure a disabled CacheManager for your Client when testing or debugging to remove 'moving parts' for better clarity into request/response behavior.

Returns:

a new disabled CacheManager instance. All caching

forResource

public static <T> CacheConfigurationBuilder forResource(Class<T> clazz)

Returns a new CacheConfigurationBuilder to configure a cache region that will store data for instances of type clazz.

This is a convenience method equivalent to named(clazz.getName()), but it could help with readability, for example:

 import static com.okta.sdk.cache.Caches.*
 ...
 newCacheManager()
     .withCache(forResource(Account.class).withTimeToIdle(10, TimeUnit.MINUTES))
     .build();
 

Type Parameters:

T - Resource sub-interface

Parameters:

clazz - the resource class that will have a backing cache region for storing data of that type

Returns:

a new CacheConfigurationBuilder to configure a cache region that will store data for instances of type clazz.

named

public static CacheConfigurationBuilder named(String name)

Returns a new CacheConfigurationBuilder used to configure a cache region with the specified name. For example:

 import static com.okta.sdk.cache.Caches.*
 ...
 newCacheManager()
     .withCache(named("myCacheRegion").withTimeToIdle(10, TimeUnit.MINUTES))
     .build();
 

Parameters:

name - the name of the cache region for which the configuration will apply

Returns:

a new CacheConfigurationBuilder used to configure a cache region with the specified name.
