Method Detail

delete

public boolean delete(Name name,
                      Map<String,Serializable> params,
                      Hints hints)
               throws IOException

Description copied from interface: CoverageAccess

Asks this CoverageAccess to entirely remove a certain Coverage from the available CoverageSources.

Many file based formats won't allow to perform such operation, but db based source should be quite happy with it.

Specified by:

delete in interface CoverageAccess

Overrides:

delete in class DefaultCoverageAccess

Returns:

true in case of success.

Throws:

IOException

access

public CoverageSource access(Name name,
                             Map<String,Serializable> params,
                             CoverageAccess.AccessType accessType,
                             Hints hints,
                             ProgressListener listener)
                      throws IOException

Description copied from interface: CoverageAccess

Retrieve a CoverageSource to access a Named Coverage.

Specified by:

access in interface CoverageAccess

Overrides:

access in class DefaultCoverageAccess

Parameters:

name - Indicate the coverage to access

params - Additional parameters as needed to indicate what part of the data set to access

accessType - Requested level of access

hints - Implementation specific hints; please review the javadocs for your Driver for details

listener - used to report progress while obtianing access

Throws:

IOException

getInfo

public ServiceInfo getInfo(ProgressListener listener)

Description copied from interface: CoverageAccess

Description of the CoverageAccess we are connected to here.

Specified by:

getInfo in interface CoverageAccess

Overrides:

getInfo in class DefaultCoverageAccess

Returns:

Description of the CoverageAccess we are connected to here.

dispose

public void dispose()

Description copied from interface: CoverageAccess

This will free any cached info object or header information.

Often a CoverageAccess will keep a file channel open, this will clean that sort of thing up.

Once a CoverageAccess has been disposed it can be seen as being in unspecified state, hence calling a method on it may have unpredictable results.

Specified by:

dispose in interface CoverageAccess

Overrides:

dispose in class DefaultCoverageAccess

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

addFile

public void addFile(String filePath)

Description copied from interface: FileSetManager

Add a file to the file set manager

Specified by:

addFile in interface FileSetManager

list

public List<String> list()

Description copied from interface: FileSetManager

Return the list of all the files currently added to the manager

Specified by:

list in interface FileSetManager

removeFile

public void removeFile(String filePath)

Description copied from interface: FileSetManager

Remove a file from the manager (An implementation may also physically remove the file)

Specified by:

removeFile in interface FileSetManager

purge

public void purge()

Description copied from interface: FileSetManager

Remove all the files from the manager (An implementation may also physically remove all the files)

Specified by:

purge in interface FileSetManager
