/**
 * Represents an operation that accepts a single {@code char}-valued argument and
 * returns no result. This is the primitive type specialization of {@link EConsumer}
 * for {@code char}. Unlike most other functional interfaces, {@link ECharConsumer}
 * is expected to operate via side-effects.
 *
 * 
 * Additionally, the functional method is allowed to throw a generic
 * {@link Throwable} of type {@code E}.
 *
 * 
 * This is a functional interface whose functional method is
 * {@link #acceptChecked(char)}.
