Method Detail

getNode

public NodeMetadata getNode(String id)

Description copied from interface: JCloudsNativeComputeServiceAdapter

Specified by:

getNode in interface ComputeServiceAdapter<NodeMetadata,Hardware,Image,Location>

Specified by:

getNode in interface JCloudsNativeComputeServiceAdapter

listNodes

public Iterable<NodeMetadata> listNodes()

Description copied from interface: JCloudsNativeComputeServiceAdapter

Specified by:

listNodes in interface ComputeServiceAdapter<NodeMetadata,Hardware,Image,Location>

Specified by:

listNodes in interface JCloudsNativeComputeServiceAdapter

listHardwareProfiles

public Iterable<Hardware> listHardwareProfiles()

Description copied from interface: JCloudsNativeComputeServiceAdapter

Hardware profiles describe available cpu, memory, and disk configurations that can be used to run a node.

To implement this method, return the library native hardware profiles available to the user. These will be used to launch nodes as a part of the template.

Specified by:

listHardwareProfiles in interface ComputeServiceAdapter<NodeMetadata,Hardware,Image,Location>

Specified by:

listHardwareProfiles in interface JCloudsNativeComputeServiceAdapter

Returns:

a non-null iterable of available hardware profiles.

See Also:

ComputeService.listHardwareProfiles()

listImages

public Iterable<Image> listImages()

Description copied from interface: JCloudsNativeComputeServiceAdapter

Images are the available configured operating systems that someone can run a node with.

To implement this method, return the library native images available to the user. These will be used to launch nodes as a part of the template.

Specified by:

listImages in interface ComputeServiceAdapter<NodeMetadata,Hardware,Image,Location>

Specified by:

listImages in interface JCloudsNativeComputeServiceAdapter

Returns:

a non-null iterable of available images.

See Also:

ComputeService.listImages()

listLocations

public Iterable<Location> listLocations()

Description copied from interface: JCloudsNativeComputeServiceAdapter

Specified by:

listLocations in interface ComputeServiceAdapter<NodeMetadata,Hardware,Image,Location>
