Package org.apache.commons.io.function
Interface IOBinaryOperator<T>
- Type Parameters:
- T- the type of the operands and result of the operator.
- All Superinterfaces:
- IOBiFunction<T,- T, - T> 
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
