Constructor Detail

DefaultFlowRule

public DefaultFlowRule(FlowRule rule)

Creates a new flow rule from an existing rule.

Parameters:

rule - new flow rule

Method Detail

id

public FlowId id()

Description copied from interface: FlowRule

Returns the ID of this flow.

Specified by:

id in interface FlowRule

Returns:

the flow ID

appId

public short appId()

Description copied from interface: FlowRule

Returns the application id of this flow.

Specified by:

appId in interface FlowRule

Returns:

an applicationId

groupId

public GroupId groupId()

Description copied from interface: FlowRule

Returns the group id of this flow.

Specified by:

groupId in interface FlowRule

Returns:

an groupId

priority

public int priority()

Description copied from interface: FlowRule

Returns the flow rule priority given in natural order; higher numbers mean higher priorities.

Specified by:

priority in interface FlowRule

Returns:

flow rule priority

deviceId

public DeviceId deviceId()

Description copied from interface: FlowRule

Returns the identity of the device where this rule applies.

Specified by:

deviceId in interface FlowRule

Returns:

device identifier

selector

public TrafficSelector selector()

Description copied from interface: FlowRule

Returns the traffic selector that identifies what traffic this rule should apply to.

Specified by:

selector in interface FlowRule

Returns:

traffic selector

treatment

public TrafficTreatment treatment()

Description copied from interface: FlowRule

Returns the traffic treatment that applies to selected traffic.

Specified by:

treatment in interface FlowRule

Returns:

traffic treatment

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Description copied from interface: FlowRule

Equality for flow rules only considers 'match equality'. This means that two flow rules with the same match conditions will be equal, regardless of the treatment or other characteristics of the flow.

Specified by:

equals in interface FlowRule

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

exactMatch

public boolean exactMatch(FlowRule rule)

Description copied from interface: FlowRule

Returns whether this flow rule is an exact match to the flow rule given in the argument.

Exact match means that deviceId, priority, selector, tableId, flowId and treatment are equal. Note that this differs from the notion of object equality for flow rules, which does not consider the flowId or treatment when testing equality.

Specified by:

exactMatch in interface FlowRule

Parameters:

rule - other rule to match against

Returns:

true if the rules are an exact match, otherwise false

toString

public String toString()

Overrides:

toString in class Object

timeout

public int timeout()

Description copied from interface: FlowRule

Returns the timeout for this flow requested by an application.

Specified by:

timeout in interface FlowRule

Returns:

integer value of the timeout

hardTimeout

public int hardTimeout()

Description copied from interface: FlowRule

Returns the hard timeout for this flow requested by an application. This parameter configure switch's flow hard timeout. In case of controller-switch connection lost, this variable can be useful.

Specified by:

hardTimeout in interface FlowRule

Returns:

integer value of the hard Timeout

reason

public FlowRule.FlowRemoveReason reason()

Description copied from interface: FlowRule

Returns the reason for the flow received from switches.

Specified by:

reason in interface FlowRule

Returns:

FlowRemoveReason value of reason

isPermanent

public boolean isPermanent()

Description copied from interface: FlowRule

Returns whether the flow is permanent i.e. does not time out.

Specified by:

isPermanent in interface FlowRule

Returns:

true if the flow is permanent, otherwise false

tableId

public int tableId()

Description copied from interface: FlowRule

Returns the table id for this rule.

Specified by:

tableId in interface FlowRule

Returns:

an integer.

table

public TableId table()

Description copied from interface: FlowRule

Returns the table identifier for this rule.

Specified by:

table in interface FlowRule

Returns:

a table identifier.

created

public long created()

Returns the wallclock time that the flow was created.

Returns:

creation time in milliseconds since epoch

builder

public static DefaultFlowRule.Builder builder()

Returns a default flow rule builder.

Returns:

builder
