java.util.Map<java.lang.String,java.lang.Object> |
getProvisioningFlags(java.util.Collection<java.lang.String> tags)
Gets flags, suitable as an argument to
obtain(Map). |
MachineProvisioningLocation<T> |
newSubLocation(java.util.Map<?,?> newFlags)
Creates a new location of the same type, but with additional creation instructions in the form of flags,
e.g.
|
T |
obtain(java.util.Map<?,?> flags)
Obtain a machine in this location.
|
void |
release(T machine)
Release a previously-obtained machine.

obtain in interface ProvisioningLocation<T extends MachineLocation>flags - Details of the desired machine (e.g. image, size, open ports, etc; some flag support is limited to selected providers).
"callerContext" can be specified to have custom logging and error messages (useful if starting machines in parallel)NoMachinesAvailableException - if there are no machines available in this location (or impls may return null, but that is discouraged)MachineProvisioningLocation<T> newSubLocation(java.util.Map<?,?> newFlags)
Implementers who wish to subclass this provisioning location for additional functionality in a specific cloud can use the relevant implementation of this method as a guide.
void release(T machine)
release in interface ProvisioningLocation<T extends MachineLocation>machine - a MachineLocation previously obtained from a call to #obtain()java.lang.IllegalStateException - if the machine did not come from a call to #obtain() or it has already been released.java.util.Map<java.lang.String,java.lang.Object> getProvisioningFlags(java.util.Collection<java.lang.String> tags)
obtain(Map). The tags provided give
hints about the machine required. The provisioning-location could be configured to
understand those tags.
For example, an AWS-location could be configured to understand that a particular entity
type (e.g. "TomcatServer") requires a particular AMI in that region, so would return the
required image id.tags -
