applyIfNotEmpty

public static <I,R,T extends Throwable> Optional<R> applyIfNotEmpty(I value,
                                                                    ThrowingFunction<I,R,T> function)

Tests whether the value is not null, an empty string, an empty collection or a map and transform it using the given function.

Parameters:

value - the value, if its a String it will be tested for text length as well

function - the function to be executed against value if not empty

Throws:

T extends Throwable

applyIfNotEmpty

public static <I,R,T extends Throwable> R applyIfNotEmpty(I value,
                                                          ThrowingFunction<I,R,T> consumer,

Tests whether the value is not null, an empty string, an empty collection or a map and transform it using the given function.

Parameters:

value - the value, if its a String it will be tested for text length as well

consumer - the function to be executed against value if not empty

orElse - the supplier to use to retrieve a result if the given value is empty

Throws:

T extends Throwable
