Method Detail
-
apply
char apply(char x)
Computes the operator on the given input.- Parameters:
x
- the input.- Returns:
- the output of the operator on the given input.
-
identity
static CharUnaryOperator identity()
Returns aUnaryOperator
that always returns the input unmodified.- See Also:
UnaryOperator.identity()

applyAsInt
@Deprecated default int applyAsInt(int x)
Deprecated.Please useapply(char)
.- Specified by:
applyAsInt
in interfacejava.util.function.IntUnaryOperator
- Throws:
java.lang.IllegalArgumentException
- If the given operands are not an element of the key domain.- Since:
- 8.5.0
- Implementation Specification:
- This default implementation delegates to
apply(char)
after narrowing down the argument to the actual key type, throwing an exception if the argument cannot be represented in the restricted domain. This is done for interoperability with the Java 8 function environment. The use of this method discouraged, as unexpected errors can occur.
