Constructor Detail

SingleAndProxiedDatabaseFile

public SingleAndProxiedDatabaseFile(DatabaseFiles proxied,
                                    ReadWritableFile f)

Create a SingleAndProxiedDatabaseFile object.

Parameters:

proxied - The proxied DatabaseFiles object.

f - The ReadWritableFile.

Method Detail

getFile

public ReadWritableFile getFile()

Get the file.

Returns:

The file.

getProxied

public DatabaseFiles getProxied()

Get the proxied DatabaseFiles object.

Returns:

The proxied DatabaseFiles object.

delete

public void delete()

Description copied from interface: DatabaseFiles

Delete the database file(s).

Specified by:

delete in interface DatabaseFiles

replaceContents

public void replaceContents(DatabaseFiles f)

Description copied from interface: DatabaseFiles

Replace the contents of the database file(s) with the contents of the supplied file(s). The implementation of this method should be able to assume that the supplied object is of the same implementation as itself. (It is up to the database backend implementation to guarantee that.)

The contents of the database files should be replaced using the ReadWritableFile.replaceContents(org.entityfs.ReadWritableFile) method. A consequence of that is that the source files should be deleted.

Specified by:

replaceContents in interface DatabaseFiles

Parameters:

f - The file(s) containing the data.
