Abstract

Consumer is a functional interface that is used to process data. A Consumer object is specified with type parameter T. Its functional method, called accept, takes an argument of type T and has return type void. Long chains of consumers can be composed to perform an operation that does not require a result to be returned. As with other functional interfaces, the composed consumer of the first two operations becomes the first operand of the second composed consumer, and so on.
