Method Detail

whitelist

public static <T> Predicate<T> whitelist(String input,
                                         Function<String,String[]> splitter,
                                         Function<String,T> factory)

Generate a whitelist filter/predicate that allows only those values that are included in the supplied input.

Parameters:

input - the input string

splitter - the function that splits the input into multiple items; may not be null

factory - the factory for creating string items into filter matches; may not be null

Returns:

the predicate that returns true if and only if the argument to the predicate matches (with equals(...) one of the objects parsed from the input; never null

whitelist

public static <T> Predicate<T> whitelist(String input,
                                         char delimiter,
                                         Function<String,T> factory)

Generate a whitelist filter/predicate that allows only those values that are included in the supplied input.

Parameters:

input - the input string

delimiter - the character used to delimit the items in the input

factory - the factory for creating string items into filter matches; may not be null

Returns:

the predicate that returns true if and only if the argument to the predicate matches (with equals(...) one of the objects parsed from the input; never null

whitelist

public static <T> Predicate<T> whitelist(String input,
                                         Function<String,T> factory)

Generate a whitelist filter/predicate that allows only those values that are included in the supplied comma-separated input.

Parameters:

input - the input string

factory - the factory for creating string items into filter matches; may not be null

Returns:

the predicate that returns true if and only if the argument to the predicate matches (with equals(...) one of the objects parsed from the input; never null

whitelist

public static Predicate<String> whitelist(String input)

Generate a whitelist filter/predicate that allows only those values that are included in the supplied comma-separated input.

Parameters:
