I - type of inputO - type of outputpublic interface UnaryOp<I,O> extends NullaryOp<O>, UnaryInput<I>
Unary ops come in three major flavors: UnaryComputerOp,
UnaryFunctionOp and UnaryInplaceOp. Additional hybrid types
union these flavors in various combinations: UnaryHybridCF,
UnaryHybridCI and UnaryHybridCFI.
A unary op may be treated as a NullaryOp by holding the input
constant.
SpecialOp.Flavor| Modifier and Type | Method and Description |
|---|---|
default int |
getArity()
Gets the op's number of special input parameters.
|
default UnaryOp<I,O> |
getIndependentInstance()
Gets a reference to an instance of this object which can be used
simultaneously from a second thread while this instance is being used from
"its" thread.

run(I input,
O output)
Executes the operation in a type-safe but flexible way.

SpecialOp
Note that this value may be larger than intuition might dictate in certain
scenarios, because UnaryOp extends NullaryOp, and
BinaryOp extends UnaryOp. This allows higher-order ops to
be treated as lower-order by holding the extra input parameters constant.
But it also means that e.g. a BinaryComputerOp which is locally
typed as UnaryComputerOp will report its arity as 2 rather than 1
as one might expect.

ThreadableIt is expected that subclasses which override this method will narrow the return type appropriately. We do not enforce this at compile time via recursive generics due to their complexity: they introduce a host of typing difficulties.
