public ResourceBackedMetadataResolver(Timer timer,
                                      Resource resource)
                               throws IOException

Constructor.

Parameters:

resource - resource from which to read the metadata file.

timer - task timer used to schedule metadata refresh tasks

Throws:

IOException - thrown if there is a problem retrieving information about the resource

ResourceBackedMetadataResolver

public ResourceBackedMetadataResolver(Resource resource)

Parameters:

resource - resource from which to read the metadata file.

Throws:

IOException - thrown if there is a problem retrieving information about the resource

Method Detail

doDestroy

protected void doDestroy()

Performs component specific destruction logic. This method is executed within the lock on the object being destroyed. The default implementation of this method is a no-op.

Overrides:

doDestroy in class AbstractReloadingMetadataResolver

getMetadataIdentifier

protected String getMetadataIdentifier()

Gets an identifier which may be used to distinguish this metadata in logging statements.

Specified by:

getMetadataIdentifier in class AbstractReloadingMetadataResolver

Returns:

identifier which may be used to distinguish this metadata in logging statements

fetchMetadata

protected byte[] fetchMetadata()
                        throws ResolverException

Fetches metadata from a source.

Specified by:

fetchMetadata in class AbstractReloadingMetadataResolver

Returns:

the fetched metadata, or null if the metadata is known not to have changed since the last retrieval

Throws:

ResolverException - thrown if there is a problem fetching the metadata
