Interface IMetadataRepository

All Superinterfaces:

IAdaptable, IQueryable<IInstallableUnit>, IRepository<IInstallableUnit>

All Known Implementing Classes:

AbstractMetadataRepository

public interface IMetadataRepository
extends IRepository<IInstallableUnit>

A metadata repository stores information about a set of installable units

This interface is not intended to be implemented by clients. Metadata repository implementations must subclass AbstractMetadataRepository rather than implementing this interface directly.

Since:

2.0

Restriction:

This interface is not intended to be implemented by clients. Instead subclass AbstractMetadataRepository

Method Detail

addInstallableUnits

void addInstallableUnits(Collection<IInstallableUnit> installableUnits)

Add the given installable units to this repository.

Parameters:

installableUnits - the installable units to add

addReferences

void addReferences(Collection<? extends IRepositoryReference> references)

Adds references to another repository to this repository. When a repository is loaded by IMetadataRepositoryManager, its references are automatically added to the repository manager's set of known repositories.

Note that this method does not add the contents of the given repositories to this repository, but merely adds the location of other repositories to the metadata of this repository.

Parameters:

references - The references to add

getReferences

Collection<IRepositoryReference> getReferences()

Returns the repositories that this repository is referencing.

Returns:

An immutable collection of repository references, possibly empty but never null.

removeInstallableUnits

boolean removeInstallableUnits(Collection<IInstallableUnit> installableUnits)

Removes all installable units in the given collection from this repository.

Parameters:

installableUnits - the installable units to remove

Returns:

true if any units were actually removed, and false otherwise

removeAll

void removeAll()

Remove all installable units from this repository.

executeBatch

IStatus executeBatch(IRunnableWithProgress runnable,
                     IProgressMonitor monitor)

Executes a runnable against this repository. It is up to the repository implementor to determine what "batch process" means, for example, it may mean that the repository index is not stored until after the runnable completes. The runnable should not execute anything in a separate thread.

Parameters:

runnable - The runnable to execute

monitor - A progress monitor that will be passed to the runnable

Returns:

The result of running the runnable. Any exceptions thrown during the execution will be returned in the status.

compress

void compress(IPool<IInstallableUnit> iuPool)

Cause semantically equivalent IInstallableUnits in the receiver to be replaced with a shared object from the provided IPool. New objects are added to the IPool as required.

While the IPool should be retained to increase the scope of sharing when calling compress(IPool) on subsequent repositories, the IPool can be discarded without adversely effecting the receiver.

Since:

2.1
