buildFlowRuleMap

public static Map<String,List<FlowRule>> buildFlowRuleMap(List<FlowRule> list)

Build the flow rule map from raw list of flow rules, grouping by resource name.

参数:

list - raw list of flow rules

返回:

constructed new flow rule map; empty map if list is null or empty, or no valid rules

buildFlowRuleMap

public static Map<String,List<FlowRule>> buildFlowRuleMap(List<FlowRule> list,
 Predicate<FlowRule> filter)

Build the flow rule map from raw list of flow rules, grouping by resource name.

参数:

list - raw list of flow rules

filter - rule filter

返回:

constructed new flow rule map; empty map if list is null or empty, or no wanted rules

buildFlowRuleMap

public static Map<String,List<FlowRule>> buildFlowRuleMap(List<FlowRule> list,
 Predicate<FlowRule> filter,
 boolean shouldSort)

Build the flow rule map from raw list of flow rules, grouping by resource name.

参数:

list - raw list of flow rules

filter - rule filter

shouldSort - whether the rules should be sorted

返回:

constructed new flow rule map; empty map if list is null or empty, or no wanted rules

buildFlowRuleMap

public static <K> Map<K,List<FlowRule>> buildFlowRuleMap(List<FlowRule> list,
 Function<FlowRule,K> groupFunction,
 Predicate<FlowRule> filter,
 boolean shouldSort)

Build the flow rule map from raw list of flow rules, grouping by provided group function.

类型参数:

K - type of key

参数:

list - raw list of flow rules

groupFunction - grouping function of the map (by key)

filter - rule filter

shouldSort - whether the rules should be sorted

返回:

constructed new flow rule map; empty map if list is null or empty, or no wanted rules

validClusterRuleId

public static boolean validClusterRuleId(Long id)

Check whether provided ID can be a valid cluster flow ID.

参数:

id - flow ID to check

返回:

true if valid, otherwise false

isValidRule

public static boolean isValidRule(FlowRule rule)

Check whether provided flow rule is valid.

参数:

rule - flow rule to check

返回:

true if valid, otherwise false

checkClusterConcurrentField

public static boolean checkClusterConcurrentField(FlowRule rule)

isWindowConfigValid

public static boolean isWindowConfigValid(int sampleCount,
 int windowIntervalMs)
