Class ChainedUserProvider

java.lang.Object

bucket.user.providers.ChainedUserProvider

All Implemented Interfaces:

com.opensymphony.user.provider.UserProvider, Serializable

Direct Known Subclasses:

ChainedAccessProvider, ChainedCredentialsProvider, ChainedProfileProvider

Deprecated.

since 6.10.0. No longer used.

@Deprecated
public abstract class ChainedUserProvider
extends Object
implements com.opensymphony.user.provider.UserProvider

Allows more explicit chaining of OSUser providers. Normal OSUser chaining is applied externally, so a provider doesn't know it's part of a chain, and can't explicitly talk to providers down the chain (making implementing a generic caching provider difficult, for example)

Init Properties:

chain.classname

The classname of the provider to instantiate that this provider may choose to delegate requests to. The class must be of the appropriate provider type.

chain.*

Any property (other than chain.classname) that starts with chain. will have the "chain." prefix stripped, and be passed as an init property to the next provider in the chain.

If you're a masochist, you can configure multiple chained providers in a row, using properties like "chain.chain.chain.of.fools" to pass configuration properties down the list.

Deprecated.

Method Detail

getProviderClass

protected abstract Class getProviderClass()

Deprecated.

Get the exact kind of provider we are chaining. Concrete subclasses should return the class we are enforcing providers to be a type of: i.e. AccessProvider, CredentialsProvider or ProfileProvider.

If this provider class isn't a sub-type of UserProvider, things will fall over in a painful fashion.

getNextProvider

protected com.opensymphony.user.provider.UserProvider getNextProvider()

Deprecated.

Get the next UserProvider in the chain. So long as the chain has been successfully init()'d, this method should never return null.

Returns:

the next AccessProvider in the chain

init

public boolean init(Properties properties)

Deprecated.

See the class Javadoc for the chaining provider's properties.

Specified by:

init in interface com.opensymphony.user.provider.UserProvider

Parameters:

properties - initialisation properties for this provider, and subsequent providers in the chain.

Returns:

true if initialisation was successful, false otherwise
