public final class UtilsCidr
extends Object

The unavoidable utility class.

It provides static functions to escape unescape, trim or removing leading?trailing quotes out of String.

It also provide additional utility functions, handy to make them unit tested.

Method Detail

getCidrFieldKey

public static String getCidrFieldKey(Tuple t)

Given a tuple, return the key of the first element that match a CIDR format.

This function is inefficient. Use if only to build things at startup.

Parameters:

t - the input tuple.

Returns:

the key of the CIDR field, or null if none found.

getCidrTrie

public static com.github.veqryn.collect.Trie<com.github.veqryn.net.Cidr4,Tuple> getCidrTrie(Tuple resource,
                                                                                            String cidrField)

Given an input resource tuple, return a CIDR Trie structure.

The resource tuple MUST be an array.

Parameters:

resource - the input resource tuple

cidrField - the tuple field key that must be used as CIDR. You can pass null, in which case the first tuple field that matches a CIDR will be used.

Returns:

your trie

Throws:

PunchRuntimeException - in case of error

getCompactCidrTrie

public static com.github.veqryn.collect.Trie<com.github.veqryn.net.Cidr4,Long> getCompactCidrTrie(org.thales.punch.libraries.punchlang.impl.operator.CompactCsv resource,
                                                                                                  String cidrField)

Parameters:

resource - your input compact csv

cidrField - the columns

Returns:

a ready to use Trie
