Method Detail

getDefinition

public JcrPackageDefinition getDefinition()
                                   throws RepositoryException

Returns the package definition of this package

Specified by:

getDefinition in interface JcrPackage

Returns:

the package definition or null if this package is not valid.

Throws:

RepositoryException - if an error occurs

compareTo

public int compareTo(JcrPackage o)

Specified by:

compareTo in interface Comparable<JcrPackage>

isValid

public boolean isValid()

Checks if the underlying node contains the correct structure.

isValid in interface JcrPackage

Returns:

true if this package is valid.

isInstalled

public boolean isInstalled()
                    throws RepositoryException

isEmpty

public boolean isEmpty()

Checks if the package has content.

Specified by:

isEmpty in interface JcrPackage

true if this package doesn't have content

getNode

public Node getNode()

Returns the underlying node

Specified by:

getNode in interface JcrPackage

Returns:

the node

isSealed

public boolean isSealed()

Checks if this package is sealed. this is the case, if it was not modified since it was unwrapped.

Specified by:

isSealed in interface JcrPackage

Returns:

true if this package is sealed.

verifyId

@Deprecated
public boolean verifyId(boolean autoFix,
                        boolean autoSave)
                 throws RepositoryException

Deprecated.

Checks if the package id is correct in respect to the installation path and adjusts it accordingly.

Specified by:

verifyId in interface JcrPackage

Parameters:

autoFix - true to automatically fix the id

autoSave - true to save changes immediately

Returns:

true always.

Throws:

RepositoryException - if an error occurs.

tryUnwrap

public void tryUnwrap()
               throws IOException,
                      RepositoryException

Tries to unwrap the definition of this package.

Throws:

IOException - if an I/O error occurs or if the underlying file is not a package

RepositoryException - if a repository error occurs

getPackage

public VaultPackage getPackage()
                        throws RepositoryException,
                               IOException

Returns the vault package stored in the data of this package. Opens the package implicitly therefore JcrPackage.close() needs to be afterwards. This is potentially a costly operation as this requires uncompressing the ZIP stream (and potentially creating temporary files) therefore prefer using JcrPackage.getDefinition() whenever possible to access meta data.

Specified by:

getPackage in interface JcrPackage

Returns:

the package, this is closed when JcrPackage.close() is called on this package

Throws:

RepositoryException - if an error occurs

IOException - if an I/O error occurs

getPackage

@NotNull
protected @NotNull VaultPackage getPackage(boolean forceFileArchive)
                                    throws RepositoryException,
                                           IOException

Creates a new package by creating the appropriate archive. This is basically a workaround to ensure that 'rewrap' has a zip file to work on. Ideally rewrap should not rely on the archive format.

Parameters:

forceFileArchive - if true a file archive is enforced

Returns:

the package

Throws:

RepositoryException - If a repository error occurs.

IOException - if an i/o error occurs.

extract

public void extract(ImportOptions opts)
             throws RepositoryException,
                    PackageException,
                    IOException

Extracts the package contents to the repository. Opens the package implicitly therefore JcrPackage.close() needs to be afterwards.

Specified by:

extract in interface JcrPackage

Parameters:

opts - import options

Throws:

RepositoryException - if a repository error during installation occurs.

PackageException - if an error during packaging occurs

IOException - if an I/O error occurs

public void install(ImportOptions opts)
             throws RepositoryException,
                    PackageException,
                    IOException

Installs the package contents to the repository but creates a snapshot if necessary. Opens the package implicitly therefore JcrPackage.close() needs to be afterwards.

Specified by:

install in interface JcrPackage

Parameters:

opts - import options

Throws:

RepositoryException - if a repository error during installation occurs.

PackageException - if an error during packaging occurs

IOException - if an I/O error occurs
