type Proxy 

type Proxy struct {
	// pluginCore.ResourceManager
	BaseResourceManager
	ResourceNamespacePrefix pluginCore.ResourceNamespace
	ExecutionIdentifier     *core.TaskExecutionIdentifier
}

A proxy will be created for each TaskExecutionContext. The Proxy of an execution contains the resource namespace prefix (e.g., "qubole-hive-executor" for a hive task) and the token prefix (e.g., ex:<project>:<domain>:<exec_id>) of that execution. The plugins will only have access to a Proxy but not directly the underlying resource manager. The Proxy will prepend proper prefixes for the resource namespace and the allocation token.

func (Proxy) AllocateResource 

func (p Proxy) AllocateResource(ctx context.Context, namespace pluginCore.ResourceNamespace,
	allocationToken string, constraintsSpec pluginCore.ResourceConstraintsSpec) (pluginCore.AllocationStatus, error)

func (p Proxy) ComposeResourceConstraint(spec pluginCore.ResourceConstraintsSpec) []FullyQualifiedResourceConstraint

func (Proxy) ReleaseResource 

func (p Proxy) ReleaseResource(ctx context.Context, namespace pluginCore.ResourceNamespace,
	allocationToken string) error
