Intent

protected Intent(ApplicationId appId,
                 Key key,
                 Collection<NetworkResource> resources,
                 int priority,
                 ResourceGroup resourceGroup)

Creates a new intent.

Parameters:

appId - application identifier

key - optional key

resources - required network resources (optional)

priority - flow rule priority

resourceGroup - the resource group for intent

Method Detail

id

public IntentId id()

Returns the intent object identifier.

Returns:

intent fingerprint

appId

public ApplicationId appId()

Returns the identifier of the application that requested the intent.

Returns:

application identifier

priority

public int priority()

Returns the priority of the intent.

Returns:

intent priority

resources

public Collection<NetworkResource> resources()

Returns the collection of resources required for this intent.

Returns:

collection of resources; may be null

resourceGroup

Returns the resource group for this intent.

Returns:

the resource group; may be null

isInstallable

public boolean isInstallable()

Indicates whether or not the intent is installable.

Returns:

true if installable

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

bindIdGenerator

public static void bindIdGenerator(IdGenerator newIdGenerator)

Binds an id generator for unique intent id generation. Note: A generator cannot be bound if there is already a generator bound.

Parameters:

newIdGenerator - id generator

unbindIdGenerator

public static void unbindIdGenerator(IdGenerator oldIdGenerator)

Unbinds an id generator. Note: The caller must provide the old id generator to succeed.

Parameters:

oldIdGenerator - the current id generator

key

public Key key()

Returns the key to identify an "Intent".

When an Intent is updated, (e.g., flow is re-routed in reaction to network topology change) related Intent object's IntentId may change, but the key will remain unchanged.

Returns:

key
