Method Detail

list

public PageSet<? extends StorageMetadata> list()

Description copied from interface: BlobStore

Lists all root-level resources available to the identity.

containerExists

public boolean containerExists(String container)

Description copied from interface: BlobStore

determines if a service-level container exists

createContainerInLocation

public boolean createContainerInLocation(Location location,
                                         String container)

Description copied from interface: BlobStore

Creates a namespace for your blobs

A container is a namespace for your objects. Depending on the service, the scope can be global, identity, or sub-identity scoped. For example, in Amazon S3, containers are called buckets, and they must be uniquely named such that no-one else in the world conflicts. In other blobstores, the naming convention of the container is less strict. All blobstores allow you to list your containers and also the contents within them. These contents can either be blobs, folders, or virtual paths.

Parameters:

location - some blobstores allow you to specify a location, such as US-EAST, for where this container will exist. null will choose a default location

container - namespace. Typically constrained to lowercase alpha-numeric and hyphens.

Returns:

true if the container was created, false if it already existed.

createContainerInLocation

public boolean createContainerInLocation(Location location,
                                         String container,
                                         CreateContainerOptions options)

options - controls default access control

getContainerAccess

public ContainerAccess getContainerAccess(String container)

setContainerAccess

public void setContainerAccess(String container,
                               ContainerAccess access)

list

public PageSet<? extends StorageMetadata> list(String container)

Description copied from class: BaseBlobStore

This implementation invokes BlobStore.list(String,org.jclouds.blobstore.options.ListContainerOptions)

Specified by:

list in interface BlobStore

Overrides:

list in class BaseBlobStore

Parameters:

container - container name

Returns:

a list that may be incomplete, depending on whether PageSet#getNextMarker is set

                                               ListContainerOptions options)

Description copied from interface: BlobStore

Like BlobStore.list(String) except you can control the size, recursion, and context of the list using options

Parameters:

container - what to list

options - size, recursion, and context of the list

Returns:

a list that may be incomplete, depending on whether PageSet#getNextMarker is set
