Method Detail

createRepository

IMetadataRepository createRepository(URI location,
                                     String name,
                                     String type,
                                     Map<String,String> properties)
                              throws ProvisionException,
                                     OperationCanceledException

Creates and returns a new empty metadata repository of the given type at the given location.

The resulting repository is added to the list of repositories tracked by the repository manager. Clients must make a subsequent call to IRepositoryManager.removeRepository(URI) if they do not want the repository manager to remember the repository for subsequent load attempts.

Parameters:

location - the absolute location for the new repository

name - the name of the new repository

type - the kind of repository to create

properties - the properties to set on the repository

Returns:

the newly created repository

Throws:

ProvisionException - if the repository could not be created. Reasons include:

• The repository type is unknown.
• There was an error writing to the given repository location.
• A repository already exists at that location.

OperationCanceledException - if this operation has been canceled

loadRepository

IMetadataRepository loadRepository(URI location,
                                   IProgressMonitor monitor)
                            throws ProvisionException,
                                   OperationCanceledException

Loads a repository corresponding to the given URL. If a repository has previously been loaded at the given location, the same cached repository may be returned.

The resulting repository is added to the list of repositories tracked by the repository manager. Clients must make a subsequent call to IRepositoryManager.removeRepository(URI) if they do not want the repository manager to remember the repository for subsequent load attempts.

Parameters:

location - The absolute location of the repository to load

monitor - a progress monitor, or null if progress reporting is not desired

Returns:

The loaded metadata repository

Throws:

OperationCanceledException - if this operation has been canceled

ProvisionException - if the repository could not be created. Reasons include:

• There is no existing repository at that location.
• The repository at that location could not be read.

loadRepository

IMetadataRepository loadRepository(URI location,
                                   int flags,
                                   IProgressMonitor monitor)
                            throws ProvisionException,
                                   OperationCanceledException

Loads a repository corresponding to the given URL. If a repository has previously been loaded at the given location, the same cached repository may be returned.

The resulting repository is added to the list of repositories tracked by the repository manager. Clients must make a subsequent call to IRepositoryManager.removeRepository(URI) if they do not want the repository manager to remember the repository for subsequent load attempts.

The flags passed in should be taken as a hint for the type of repository to load. If the manager cannot load a repository that satisfies these hints, it can fail fast.

Parameters:

location - The absolute location of the repository to load

flags - - bit-wise or of flags to consider when loading the repository (currently only IRepositoryManager.REPOSITORY_HINT_MODIFIABLE is supported)

monitor - a progress monitor, or null if progress reporting is not desired

Returns:

The loaded metadata repository

Throws:

OperationCanceledException - if this operation has been canceled

ProvisionException - if the repository could not be created. Reasons include:

• There is no existing repository at that location.
• The repository at that location could not be read.

See Also:

IRepositoryManager.REPOSITORY_HINT_MODIFIABLE

refreshRepository

IMetadataRepository refreshRepository(URI location,
                                      IProgressMonitor monitor)
                               throws ProvisionException,
                                      OperationCanceledException

Refreshes the repository corresponding to the given URL. This method discards any cached state held by the repository manager and reloads the repository contents. The provided repository location must already be known to the repository manager.

Parameters:

location - The absolute location of the repository to refresh

monitor - a progress monitor, or null if progress reporting is not desired

Returns:

The refreshed metadata repository

Throws:

OperationCanceledException - if this operation has been canceled

ProvisionException - if the repository could not be refreshed. Reasons include:

• The location is not known to the repository manager.
• There is no existing repository at that location.
• The repository at that location could not be read.
