Method Detail

getLongFromMAC

public static Long getLongFromMAC(org.pcap4j.util.MacAddress macAddress)

toMap

public static Map<String,String> toMap(Dictionary<String,?> dictionary)

matchingSubset

public static Map<String,String> matchingSubset(Map<String,String> properties,
                                                String prefix,
                                                boolean keepPrefix)

Extracts a specific property key subset from the map passed. The prefix may be removed from the keys in the resulting map, or it may be kept. In the latter case, exact matches on the prefix will also be copied into the resulting map.

Parameters:

prefix - is the key prefix to filter the map keys by.

keepPrefix - if true, the key prefix is kept in the resulting map. As side-effect, a key that matches the prefix exactly will also be copied. If false, the resulting dictionary's keys are shortened by the prefix. An exact prefix match will not be copied, as it would result in an empty string key.

Returns:

a map matching the filter key. May be an empty map, if no prefix matches were found.

Map.get() is used to assemble matches

getProperty

public static String getProperty(Map<String,String> properties,
                                 String key)
