public static final Function<String,String> TO_LOWER_CASE

Function of toLowerCase(String) method.

Method Details

prepareIdentifierCompareLocale

public static void prepareIdentifierCompareLocale()

toLowerCase

public static String toLowerCase(String identifier)

Converts the given identifier string to lowercase. The rule of conversion is subject to the language defined in crowd.identifier.language system property.

Parameters:

identifier - the identifier string, null allowed.

Returns:

lowercase identifier.

toLowerCase

public static Set<String> toLowerCase(Collection<? extends String> identifiers)

Converts the given set identifier string to lowercase. The rule of conversion is subject to the language defined in crowd.identifier.language system property.

Parameters:

identifiers - the identifier strings, nulls allowed.

Returns:

set of lowercase identifier.

containsIdentifierPredicate

public static Predicate<String> containsIdentifierPredicate(Collection<String> identifiers)

Parameters:

identifiers - the identifier strings, nulls allowed.

Returns:

Predicate returning whether given identifier is in identifiers, ignoring case

compareToInLowerCase

public static int compareToInLowerCase(String identifier1,
 String identifier2)

Converts the two given identifier strings to lowercase and compare them. The rule of conversion is subject to the language defined in crowd.identifier.language system property.

Parameters:

identifier1 - identifier. Must not be null

identifier2 - identifier. Must not be null

Returns:

comparison result similar to as Comparator.compare(Object, Object)}

equalsInLowerCase

public static boolean equalsInLowerCase(String identifier1,
 String identifier2)

Converts the two given identifier strings to lowercase and check for equality. The rule of conversion is subject to the language defined in crowd.identifier.language system property.

Parameters:

identifier1 - identifier. Can be null

identifier2 - identifier. Can be null

Returns:

true if equal, otherwise false.

hasLeadingOrTrailingWhitespace

public static boolean hasLeadingOrTrailingWhitespace(String s)

Parameters:

s - a non-null identifier

Returns:

true if this identifier starts or ends with white space

containsIdentifierBiPredicate

public static BiPredicate<String,String> containsIdentifierBiPredicate(Map<String,List<String>> map)

Returns function that checks presence of an entry in the original Map, ignoring string casing.

Parameters:

map - original case sensitive map

Returns:

function that checks presence of an entry in the original Map, ignoring string casing
