Package com.globalmentor.io.function
Interface IOUnaryOperator<T>
- Type Parameters:
T
- the type of the operand and result of the operator
- All Superinterfaces:
IOFunction<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.
Represents an operation on a single operand that produces a result of the same type as its operand. This is a specialization of
Function
for the case
where the operand and result are of the same type.
This interface is similar to UnaryOperator
except that it is allowed to throw an IOException
.
