public NoopDatabaseBackedContentManager()

Method Details

test

public boolean test(String path)

Description copied from interface: DatabaseBackedContentManager

Test if the content at the given path should be stored in the database.

Specified by:

test in interface DatabaseBackedContentManager

Parameters:

path - the path of the content relative to the root of store

Returns:

true if the content should be stored in the database, false otherwise

preStore

public byte[] preStore(String path,
 byte[] bytes)

Description copied from interface: DatabaseBackedContentManager

Process the content before it is stored in the database. The path of the file is also provided, so that the processor can decide to process the content based on the path. Note that the implementation should take care to select the same paths as in DatabaseBackedContentManager.postRetrieve(String, byte[])

The most important use case for this method is to compress the content before it is stored in the database.

Specified by:

preStore in interface DatabaseBackedContentManager

Parameters:

path - the path of the content relative to the root of store

bytes - the content to be stored

Returns:

the processed content

postRetrieve

public byte[] postRetrieve(String path,
 byte[] bytes)

Description copied from interface: DatabaseBackedContentManager

Process the content after it is retrieved from the database. The path of the file is also provided, so that the processor can decide to process the content based on the path. Note that the implementation should take care to select the same paths as in DatabaseBackedContentManager.preStore(String, byte[])

The most important use case for this method is to decompress the content after it is retrieved from the database (assuming it was compressed before it was stored).

Specified by:

postRetrieve in interface DatabaseBackedContentManager

Parameters:

path - the path of the content relative to the root of store

bytes - the content to be processed

Returns:

the processed content
