AbstractLocation |
configure(java.util.Map<?,?> properties)
Will set fields from flags, and put the remaining ones into the 'leftovers' map.
|
java.util.Map<java.lang.String,java.lang.Object> |
getProvisioningFlags(java.util.Collection<java.lang.String> tags)
Gets flags, suitable as an argument to
MachineProvisioningLocation.obtain(Map) . |
void |
init()
Called by framework (in new-style instances where spec was used) after configuring etc,
but before a reference to this instance is shared.
|
AggregatingMachineProvisioningLocation<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() |
T |
obtain(java.util.Map<?,?> flags)
Obtain a machine in this location.
|
void |
release(T machine)
Release a previously-obtained machine.

To preserve backwards compatibility for if the instance is constructed directly, one can call the code below, but that means it will be called after references to this policy have been shared with other entities.

To be overridden by AbstractEntity, AbstractLoation, AbstractPolicy, AbstractEnricher, etc.
But should not be overridden by specific entity types. If you do, the entity may break in subsequent releases. Also note that if you require fields to be initialized you must do that in this method. You must *not* rely on field initializers because they may not run until *after* this method (this method is invoked by the constructor in this class, so initializers in subclasses will not have run when this overridden method is invoked.)

. 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.getProvisioningFlags
