Method Detail

list

public PageSet<? extends StorageMetadata> list()

This implementation invokes CommonSwiftClient.listContainers(org.jclouds.openstack.swift.options.ListContainerOptions...)

containerExists

public boolean containerExists(String container)

This implementation invokes CommonSwiftClient.containerExists(java.lang.String)

Parameters:

container - container name

createContainerInLocation

public boolean createContainerInLocation(Location location,
                                String container)

This implementation invokes CommonSwiftClient#putBucketInRegion

Parameters:

location - currently ignored

container - container name

Returns:

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

list

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

This implementation invokes CommonSwiftClient.listObjects(java.lang.String, org.jclouds.openstack.swift.options.ListContainerOptions...)

Parameters:

container - container name

options - size, recursion, and context of the list

Returns:

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

blobExists

public boolean blobExists(String container,
                 String key)

This implementation invokes CommonSwiftClient#blobExists

Parameters:

container - container name

key - file name

blobMetadata

public BlobMetadata blobMetadata(String container,
                        String key)

This implementation invokes CommonSwiftClient.getObjectInfo(java.lang.String, java.lang.String)

Parameters:

container - container name

key - file name

Returns:

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

getBlob

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

This implementation invokes CommonSwiftClient.getObject(java.lang.String, java.lang.String, org.jclouds.http.options.GetOptions...)

Parameters:

container - container name

key - file name

optionsList - byte range or condition options

Returns:

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

putBlob

public String putBlob(String container,
             Blob blob)

This implementation invokes CommonSwiftClient.putObject(java.lang.String, org.jclouds.openstack.swift.domain.SwiftObject)

Parameters:

container - container name

blob - object

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 CommonSwiftClient.putObject(java.lang.String, org.jclouds.openstack.swift.domain.SwiftObject)

Parameters:

container - container name

blob - object

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 CommonSwiftClient.removeObject(java.lang.String, java.lang.String)

Parameters:

container - container name

key - file name

deleteAndVerifyContainerGone

protected boolean deleteAndVerifyContainerGone(String container)

Specified by:

deleteAndVerifyContainerGone in class BaseBlobStore

createContainerInLocation

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

options - controls default access control
