Method Detail

blobMetadata

public BlobMetadata blobMetadata(String container,
                                 String key)

This implementation invokes AtmosClient.headFile(java.lang.String)

Parameters:

container - container where this exists.

key - fully qualified name relative to the container.

Returns:

null if name isn't present or the blob you intended to receive.

deleteAndVerifyContainerGone

protected boolean deleteAndVerifyContainerGone(String container)

This implementation invokes AtmosAsyncClient.deletePath(java.lang.String) followed by AtmosAsyncClient.pathExists(java.lang.String) until it is true.

Specified by:

deleteAndVerifyContainerGone in class BaseBlobStore

createContainerInLocation

public boolean createContainerInLocation(Location location,
                                         String container)

This implementation invokes AtmosClient.createDirectory(java.lang.String, org.jclouds.atmos.options.PutOptions...)

Parameters:

location - currently ignored

container - directory name

Returns:

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

createDirectory

public void createDirectory(String container,
                            String directory)

This implementation invokes AtmosClient.createDirectory(java.lang.String, org.jclouds.atmos.options.PutOptions...)

Specified by:

createDirectory in interface BlobStore

Overrides:

createDirectory in class BaseBlobStore

Parameters:

container - directory name

directory - virtual path

deleteDirectory

public void deleteDirectory(String containerName,
                            String directory)

This implementation invokes removeBlob(java.lang.String, java.lang.String)

Specified by:

deleteDirectory in interface BlobStore

Overrides:

deleteDirectory in class BaseBlobStore

containerExists

public boolean containerExists(String container)

This implementation invokes AtmosClient.pathExists(java.lang.String)

directoryExists

public boolean directoryExists(String container,
                               String directory)

This implementation invokes AtmosClient.pathExists(java.lang.String)

Specified by:

directoryExists in interface BlobStore

Overrides:

directoryExists in class BaseBlobStore

Parameters:

container - container where the directory resides

directory - virtual path

blobExists

public boolean blobExists(String container,
                          String key)

This implementation invokes AtmosClient.pathExists(java.lang.String)

Parameters:

container - container

key - file name

getBlob

public Blob getBlob(String container,
                    String key,
                    GetOptions options)

This implementation invokes AtmosClient.readFile(java.lang.String, org.jclouds.http.options.GetOptions...)

Parameters:

container - container where this exists.

key - fully qualified name relative to the container.

options - byte range or condition options

Returns:

the blob you intended to receive or null, if it doesn't exist.

list

public PageSet<? extends StorageMetadata> list()

This implementation invokes AtmosClient.listDirectories(org.jclouds.atmos.options.ListOptions...)

list

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

This implementation invokes AtmosClient.listDirectory(java.lang.String, org.jclouds.atmos.options.ListOptions...)

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

putBlob

public String putBlob(String container,
                      Blob blob)

This implementation invokes AtmosClient.createFile(java.lang.String, org.jclouds.atmos.domain.AtmosObject, org.jclouds.atmos.options.PutOptions...)

Since there is no etag support in atmos, we just return the path.

Parameters:

container - container to place the blob.

blob - fully qualified name relative to the container.

Returns:

etag of the blob you uploaded, possibly null where etags are unsupported

putBlob

public String putBlob(String container,
                      Blob blob,
                      PutOptions options)

This implementation invokes AtmosClient.createFile(java.lang.String, org.jclouds.atmos.domain.AtmosObject, org.jclouds.atmos.options.PutOptions...)

Since there is no etag support in atmos, we just return the path.

Parameters:

container - container to place the blob.

blob - fully qualified name relative to the container.

options - byte range options

Returns:

etag of the blob you uploaded, possibly null where etags are unsupported

removeBlob

public void removeBlob(String container,
                       String key)

This implementation invokes AtmosClient.deletePath(java.lang.String)

Parameters:

container - container where this exists.

key - fully qualified name relative to the container.

createContainerInLocation

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

options - controls default access control
