                DSpaceObject parent,
                PackageParameters params,
                InputStream stream)

ingest

public DSpaceObject ingest(Context context,
                  DSpaceObject parent,
                  File pkgFile,
                  PackageParameters params,

                           SQLException,
                           IOException

Description copied from interface: PackageIngester

Create new DSpaceObject out of the ingested package. The object is created under the indicated parent. This creates a DSpaceObject. For Items, it is up to the caller to decide whether to install it or submit it to normal DSpace Workflow.

The deposit license (Only significant for Item) is passed explicitly as a string since there is no place for it in many package formats. It is optional and may be given as null.

Use ingestAll method to perform a recursive ingest of all packages which are referenced by an initial package.

Specified by:

ingest in interface PackageIngester

Parameters:

context - DSpace context.

parent - parent under which to create new object (may be null -- in which case ingester must determine parent from package or throw an error).

pkgFile - The package file to ingest

params - Properties-style list of options (interpreted by each packager).

license - may be null, which takes default license.

Returns:

DSpaceObject created by ingest.

Throws:

PackageValidationException - if package is unacceptable or there is a fatal error turning it into a DSpaceObject.

CrosswalkException - if crosswalk error

AuthorizeException - if authorization error

SQLException - if database error

IOException - if IO error

PackageException

ingestAll

public List<String> ingestAll(Context context,
                     DSpaceObject parent,
                     File pkgFile,
                     PackageParameters params,
                     String license)
                       throws PackageException,
                              UnsupportedOperationException,
                              CrosswalkException,
                              AuthorizeException,
                              SQLException,
                              IOException

Description copied from interface: PackageIngester

Recursively create one or more DSpace Objects out of the contents of the ingested package (and all other referenced packages). The initial object is created under the indicated parent. All other objects are created based on their relationship to the initial object.

For example, a scenario may be to create a Collection based on a collection-level package, and also create an Item for every item-level package referenced by the collection-level package.

The output of this method is one or more newly created DSpaceObject Identifiers (i.e. Handles).

The packager may choose not to implement ingestAll, or simply forward the call to ingest if it is unable to support recursive ingestion.

The deposit license (Only significant for Item) is passed explicitly as a string since there is no place for it in many package formats. It is optional and may be given as null.

Specified by:

ingestAll in interface PackageIngester

Parameters:

context - DSpace context.

parent - parent under which to create the initial object (may be null -- in which case ingester must determine parent from package or throw an error).

pkgFile - The initial package file to ingest

params - Properties-style list of options (interpreted by each packager).

license - may be null, which takes default license.

Returns:

List of Identifiers of DSpaceObjects created

Throws:

PackageValidationException - if initial package (or any referenced package) is unacceptable or there is a fatal error in creating a DSpaceObject

UnsupportedOperationException - if this packager does not implement ingestAll

CrosswalkException - if crosswalk error

AuthorizeException - if authorization error

SQLException - if database error

IOException - if IO error

PackageException

replace

public DSpaceObject replace(Context context,
                   DSpaceObject dso,
                   File pkgFile,
                   PackageParameters params)
                     throws PackageException,
                            UnsupportedOperationException,
                            CrosswalkException,
                            AuthorizeException,
                            SQLException,
                            IOException

Description copied from interface: PackageIngester

Replace an existing DSpace Object with contents of the ingested package. The packager may choose not to implement replace, since it somewhat contradicts the archival nature of DSpace. The exact function of this method is highly implementation-dependent.

Use replaceAll method to perform a recursive replace of objects referenced by a set of packages.

Specified by:

replace in interface PackageIngester

Parameters:

context - DSpace context.

dso - existing DSpace Object to be replaced, may be null if object to replace can be determined from package

pkgFile - The package file to ingest.

params - Properties-style list of options specific to this packager

Returns:

DSpaceObject with contents replaced

Throws:

PackageValidationException - if package is unacceptable or there is a fatal error turning it into an Item.

UnsupportedOperationException - if this packager does not implement replace.

CrosswalkException - if crosswalk error

AuthorizeException - if authorization error

SQLException - if database error

IOException - if IO error

PackageException

replaceAll

public List<String> replaceAll(Context context,
                      DSpaceObject dso,
                      File pkgFile,
                      PackageParameters params)
                        throws PackageException,
                               UnsupportedOperationException,
                               CrosswalkException,
                               AuthorizeException,
                               SQLException,
                               IOException

Description copied from interface: PackageIngester

Recursively replace one or more DSpace Objects out of the contents of the ingested package (and all other referenced packages). The initial object to replace is indicated by dso. All other objects are replaced based on information provided in the referenced packages.

For example, a scenario may be to replace a Collection based on a collection-level package, and also replace *every* Item in that collection based on the item-level packages referenced by the collection-level package.

Please note that since the dso input only specifies the initial object to replace, any additional objects to replace must be determined based on the referenced packages (or initial package itself).

The output of this method is one or more replaced DSpaceObject Identifiers (i.e. Handles).

The packager may choose not to implement replaceAll, since it somewhat contradicts the archival nature of DSpace. It also may choose to forward the call to replace if it is unable to support recursive replacement.

Specified by:

replaceAll in interface PackageIngester

Parameters:

context - DSpace context.

dso - initial existing DSpace Object to be replaced, may be null if object to replace can be determined from package

pkgFile - The package file to ingest.

params - Properties-style list of options specific to this packager

Returns:

List of Identifiers of DSpaceObjects replaced

Throws:

PackageValidationException - if initial package (or any referenced package) is unacceptable or there is a fatal error in creating a DSpaceObject

UnsupportedOperationException - if this packager does not implement replaceAll

CrosswalkException - if crosswalk error

AuthorizeException - if authorization error

SQLException - if database error

IOException - if IO error

PackageException

getParameterHelp

public String getParameterHelp()

Returns a user help string which should describe the additional valid command-line options that this packager implementation will accept when using the -o or --option flags with the Packager script.

Specified by:

getParameterHelp in interface PackageIngester

Returns:

a string describing additional command-line options available with this packager
