Method Detail

accept

void accept(T t)
     throws E extends Exception

Performs this operation on the given argument.

Parameters:

t - the input argument

Throws:

E - in case of an error during the data consumption

E extends Exception

andThen

default FailableConsumer<T,E> andThen(FailableConsumer<? super T,? extends E> after)

Similar to andThen method of Consumer

Parameters:

after - the operation to perform after this operation

Returns:

a composed FailableConsumer that performs in sequence this operation followed by the after operation

fromConsumer

static <T,E extends Exception> FailableConsumer<T,E> fromConsumer(Consumer<T> consumer)

Utility method for wrapping a consumer with a failable consumer

Type Parameters:

T - The type of the data being consumed

E - The exception type

Parameters:

consumer - The consumer to wrap

Returns:

The failable consumer (which effectively never throws checked exceptions)
