Method Detail

getFlowRuleCount

int getFlowRuleCount()

Returns the number of flow rules in the store.

Returns:

number of flow rules

getFlowRuleCount

default int getFlowRuleCount(DeviceId deviceId)

Returns the number of flow rules for the given device in the store.

Parameters:

deviceId - device identifier

Returns:

number of flow rules for the given device

getFlowEntry

FlowEntry getFlowEntry(FlowRule rule)

Returns the stored flow.

Parameters:

rule - the rule to look for

Returns:

a flow rule

getFlowEntries

Iterable<FlowEntry> getFlowEntries(DeviceId deviceId)

Returns the flow entries associated with a device.

Parameters:

deviceId - the device ID

Returns:

the flow entries

storeFlowRule

@Deprecated
void storeFlowRule(FlowRule rule)

Deprecated. in Cardinal Release

// TODO: Better description of method behavior. Stores a new flow rule without generating events.

Parameters:

rule - the flow rule to add

storeBatch

void storeBatch(FlowRuleBatchOperation batchOperation)

Stores a batch of flow rules.

Parameters:

batchOperation - batch of flow rules. A batch can contain flow rules for a single device only.

batchOperationComplete

void batchOperationComplete(FlowRuleBatchEvent event)

Invoked on the completion of a storeBatch operation.

Parameters:

event - flow rule batch event

deleteFlowRule

void deleteFlowRule(FlowRule rule)

Marks a flow rule for deletion. Actual deletion will occur when the provider indicates that the flow has been removed.

Parameters:

rule - the flow rule to delete

addOrUpdateFlowRule

FlowRuleEvent addOrUpdateFlowRule(FlowEntry rule)

Stores a new flow rule, or updates an existing entry.

Parameters:

rule - the flow rule to add or update

Returns:

flow_added event, or null if just an update

removeFlowRule

FlowRuleEvent removeFlowRule(FlowEntry rule)

Parameters:

rule - the flow entry to remove

Returns:

flow_removed event, or null if nothing removed

pendingFlowRule

FlowRuleEvent pendingFlowRule(FlowEntry rule)

Marks a flow rule as PENDING_ADD during retry. Emits flow_update event if the state is changed

Parameters:

rule - the flow rule that is retrying

Returns:

flow_updated event, or null if nothing updated

purgeFlowRule

default void purgeFlowRule(DeviceId deviceId)

Removes all flow entries of given device from store.

Parameters:

deviceId - device id

purgeFlowRules

void purgeFlowRules()

Removes all flow entries from store.

updateTableStatistics

FlowRuleEvent updateTableStatistics(DeviceId deviceId,
                                    List<TableStatisticsEntry> tableStats)

Updates the flow table statistics of the specified device using the given statistics.

Parameters:

deviceId - device identifier

tableStats - list of table statistics

Returns:

ready to send event describing what occurred;

getTableStatistics

Iterable<TableStatisticsEntry> getTableStatistics(DeviceId deviceId)

Returns the flow table statistics associated with a device.

Parameters:

deviceId - the device ID

Returns:

the flow table statistics

getActiveFlowRuleCount

long getActiveFlowRuleCount(DeviceId deviceId)

Returns number of flow rules in ADDED state for specified device.

Parameters:

deviceId - the device ID
