Class ResourceBundleManager

java.lang.Object
oracle.javatools.resourcebundle.ResourceBundleManager

Direct Known Subclasses:

ResourceBundleManagerDT, ResourceBundleManagerRT

public abstract class ResourceBundleManager

extends java.lang.Object

Manager class for resource bundle support in the Oracle Fusion Platform. Callers should obtain obtain a reference to this class through the static getResourceBundleManager()method. ResourceBundleWrapper instances are obtained via the getBundle() of the ResourceBundleManagerRT or ResourceBundleManagerDT subclasses, and should be released using releaseBundle(ResourceBundleWrapper) when they are no longer used. * ResourceBundleManager provides a cache of resource bundles that can be tuned via the following system properties: - resource-bundle-cache-initial-size (default 100) - resource-bundle-cache-max-size (default 100) - resource-bundle-cache-load-factor (default 0.75f) - resource-bundle-cache-expire-time (default 43200000 ie, 12 hours) resource-bundle-cache-initial-size defines the size the cache will be initially created to hold resource-bundle-cache-max-size defines the maximum number of resource bundles the cache will hold resource-bundle-cache-load-factor defines the load factor used in deciding when to increase the size of the cache resource-bundle-cache-expire-time defines the number of milliseconds a bundle can be in the cache before it is considered expired. Expired bundles will be removed from the cache when a new entry is added to the cache. Design-time implementations of the (@link ResourceBundleWrapper} must extend oracle.ide.resourcebundle.NodeResourceBundle so that the ResourceBundleManager can properly interract with the implementation. NodeResourceBundle contains methods that only the design-time ResourceBundleManagerDT implementation will use, such as delete() and Node methods such as save() Run-time implementations of the ResourceBundleWrapper must extend <@link ResourceBundleWrapperRT}.

ResourceBundleManager

protected ResourceBundleManager(ResourceBundleCacheConfig config)

Method Detail

deleteBundle

public abstract boolean deleteBundle(ResourceBundleWrapper bundle)

Deletes the given bundle.

Parameters:

bundle - Deletes the given resource bundle.

Returns:

true on success.

Throws:

java.lang.NullPointerException - if bundle is null

mergeBundles

public abstract boolean mergeBundles(ResourceBundleWrapper newBundle,
                                     ResourceBundleWrapper oldBundle)

Merges the contents of oldBundle into newBundle

Parameters:

newBundle - The new resource bundle.

oldBundle - The old resource bundle, whose contents are merged into the new bundle.

Returns:

true on success.

Throws:

java.lang.NullPointerException - if newBundle or oldBundle is null

splitBundle

public abstract boolean splitBundle(ResourceBundleWrapper newBundle,
                                    ResourceBundleWrapper oldBundle,
                                    java.util.Set<java.lang.String> keysToMove)

Splits a ResourceBundleWrapper into two. The keys contained in keysToMove will be removed from oldBundle and added to newBundle

oldBundle - The original (old) resource bundle

keysToMove - The set of keys to move

Returns:

true on success.

Throws:

java.lang.NullPointerException - if newBundle,oldBundle, or keysToMove is null

java.lang.IllegalArgumentException - if keysToMove is an empty Set.

releaseBundle

public abstract boolean releaseBundle(ResourceBundleWrapper bundle)

Releases the ResourceBundleWrapper and all associated resources, once released the old resource bundle should not be used anymore, or it will throw an IllegalStateException.

Parameters:

bundle - The resource bundle to release.

Returns:

true on success.

Throws:

java.lang.NullPointerException - if bundle is null

setDefaultResourceKeyGenerator
