/**
* Represents an operation that accepts three input arguments and returns no
* result. This is the three-arity specialization of {@link Consumer}.
* Unlike most other functional interfaces, {@code TriConsumer} is expected
* to operate via side-effects.
*
* This can be used anywhere you need to apply an operation to three input parameters
* and don't need to return a result, for example, in handling events with three attributes.
*
*
This is a functional interface
* whose functional method is {@link #accept(Object, Object, Object)}.
*
* @param the type of the first argument to the operation
* @param the type of the second argument to the operation
* @param the type of the third argument to the operation

* Returns a composed {@code TriConsumer} that performs, in sequence, this
* operation followed by the {@code after} operation. If performing either
* operation throws an exception, it is relayed to the caller of the
* composed operation. If performing this operation throws an exception,
* the {@code after} operation will not be performed.
*
* This can be useful in scenarios where you have several operations that
* must be performed on the same set of input parameters, possibly by different parts
* of your code.
