Method Details
-
applyWithException
Applies this function to the given argument, possibly throwing a checked exception.- Parameters:
t
- the first function argumentu
- the second function argument- Returns:
- the function result
- Throws:
Exception
- on error
-
apply
DefaultBiFunction.apply(Object, Object)
that wraps any thrown checked exceptions (by default in aRuntimeException
).- Specified by:
apply
in interfaceBiFunction<T,
U, R> - Parameters:
t
- the first function argumentu
- the second function argument- Returns:
- the function result

.- Parameters:
t
- the first function argumentu
- the second function argumentexceptionWrapper

of
Lambda friendly convenience method that can be used to create aThrowingBiFunction
where theapply(Object, Object)
method wraps any checked exception thrown by the supplied lambda expression or method reference.This method can be especially useful when working with method references. It allows you to easily convert a method that throws a checked exception into an instance compatible with a regular
BiFunction
.For example:
map.replaceAll(ThrowingBiFunction.of(Example::methodThatCanThrowCheckedException));
- Type Parameters:
T
- the type of the first argument to the functionU
- the type of the second argument to the functionR
- the type of the result of the function- Parameters:
function
- the source function- Returns:
- a new
ThrowingFunction
instance

where theapply(Object, Object)
method wraps any thrown checked exceptions using the givenexceptionWrapper
.This method can be especially useful when working with method references. It allows you to easily convert a method that throws a checked exception into an instance compatible with a regular
