Method Details

newReadOnlyBlobStore

public static BlobStore newReadOnlyBlobStore(BlobStore blobStore)

getContext

public BlobStoreContext getContext()

Specified by:

getContext in interface BlobStore

Overrides:

getContext in class ForwardingBlobStore

Returns:

a reference to the context that created this BlobStore.

blobBuilder

public BlobBuilder blobBuilder(String name)

Specified by:

blobBuilder in interface BlobStore

Overrides:

blobBuilder in class ForwardingBlobStore

Returns:

builder for creating new Blobs

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.

Specified by:

createContainerInLocation in interface BlobStore

Overrides:

createContainerInLocation in class ForwardingBlobStore

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 createContainerOptions)

Specified by:

createContainerInLocation in interface BlobStore

Overrides:

createContainerInLocation in class ForwardingBlobStore

Parameters:

createContainerOptions - controls default access control

See Also:

Parameters:

container - what to clear

clearContainer

public void clearContainer(String container,
 ListContainerOptions options)

Description copied from interface: BlobStore
