== Members

[#getWithException_]
=== getWithException()

Gets a result, possibly throwing a checked exception.

[#get_]
=== get()

Default _Supplier#get()_ that wraps any thrown checked exceptions (by default in a _RuntimeException_ ).

[#get_BiFunction]
=== get(BiFunction)

Gets a result, wrapping any thrown checked exceptions using the given _exceptionWrapper_ .

[#throwing_BiFunction]
=== throwing(BiFunction)

Return a new xref:refguide:commons:index/functional/ThrowingSupplier.adoc[ThrowingSupplier] where the _#get()_ method wraps any thrown checked exceptions using the given _exceptionWrapper_ .

[#of_ThrowingSupplier]
=== of(ThrowingSupplier)

Lambda friendly convenience method that can be used to create a xref:refguide:commons:index/functional/ThrowingSupplier.adoc[ThrowingSupplier] where the _#get()_ 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 _Supplier_ .

For example:

----

optional.orElseGet(ThrowingSupplier.of(Example::methodThatCanThrowCheckedException));
----

[#of_ThrowingSupplier_BiFunction]
=== of(ThrowingSupplier, BiFunction)

Lambda friendly convenience method that can be used to create xref:refguide:commons:index/functional/ThrowingSupplier.adoc[ThrowingSupplier] where the _#get()_ method wraps any thrown checked exceptions using the given _exceptionWrapper_ .

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 _Supplier_ .

For example:

----

optional.orElseGet(ThrowingSupplier.of(Example::methodThatCanThrowCheckedException, IllegalStateException::new));
----
