Interface DocumentDataProviderRegistry

public interface DocumentDataProviderRegistry

Central registration for DocumentDataProvider implementations. A DocumentDataProviderRegistry manages instances of DocumentDataProvider implementations for given Source and PageSegmentHandle instances. Usually accessed by calling com.levigo.jadice.web.conn.server.WebtoolkitServerContext#getDocumentDataProviderRegistry() .

Method Details

registerProvider

<S extends Source,
SH extends PageSegmentHandle>
void registerProvider(Class<S> source,
 Class<SH> sourceHandle,
 DocumentDataProvider<S,SH> provider)

Registers a DocumentDataProvider implementation for the provided Source and PageSegmentHandle types.

Type Parameters:

S - The actual Source.

SH - The actual PageSegmentHandle.

Parameters:

source - A use-case-specific implementation of a Source.

sourceHandle - A use-case-specific implementation of a PageSegmentHandle.

provider - The DocumentDataProvider implementation to be used for a given Source or PageSegmentHandle.

registerProvider

<S extends Source,
SH extends PageSegmentHandle>
void registerProvider(Class<S> source,
 Class<SH> sourceHandle,
 ContextualFactory<? extends DocumentDataProvider<S,SH>> providerFactory)

Registers a ContextualFactory instance to create a DocumentDataProvider. The ContextualFactory indirection allows to create instances specific to the context of the invocation.

Type Parameters:

S - the actual Source.

SH - the actual PageSegmentHandle

Parameters:

source - a class extending Source

sourceHandle - a class extending PageSegmentHandle

providerFactory - a ContextualFactory in charge to create DocumentDataProvider implementations based on the InvocationContext

getProviderBySource

<S extends Source>
ContextualFactory<DocumentDataProvider<S,?>> getProviderBySource(Class<S> source)

Gets a previously registered ContextualFactory instance to create a DocumentDataProvider.

Type Parameters:

S - The actual Source.

Parameters:

source - A use-case-specific implementation of a Source.

Returns:

the ContextualFactory instance

getProviderByHandle

<SH extends PageSegmentHandle>
ContextualFactory<DocumentDataProvider<?,SH>> getProviderByHandle(Class<SH> sourceHandle)

Gets a previously registered ContextualFactory instance to create a DocumentDataProvider.

Type Parameters:

SH - the actual PageSegmentHandle

Parameters:

sourceHandle - a class extending PageSegmentHandle

Returns:

the ContextualFactory instance
