Modifier and Type	Method and Description
public default T	get() Implements java.util.function.Supplier.get. Default `Supplier#get()` that wraps any thrown checked exceptions (by default in a `RuntimeException`).
public default T	Returns: a result get(BiFunction<String, Exception, RuntimeException> `BiFunction` that wraps the given message and checked exception into a runtime exception exceptionWrapper) Gets a result, wrapping any thrown checked exceptions using the given `exceptionWrapper`.
public T	Returns: a result getWithException() Gets a result, possibly throwing a checked exception.
public static < the type of results supplied by this supplier T> ThrowingSupplier<T>	Returns: a new `ThrowingSupplier` instance of(ThrowingSupplier<T> the source supplier supplier) Lambda friendly convenience method that can be used to create a `ThrowingSupplier` where the `get()` method wraps any checked exception thrown by the supplied lambda expression or method reference.

public static <T> ThrowingSupplier<T> of(ThrowingSupplier<T> supplier) Lambda friendly convenience method that can be used to create a `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)); Parameters <T> the type of results supplied by this supplier supplier:ThrowingSupplier<T> the source supplier Returns:ThrowingSupplier<T> a new `ThrowingSupplier` instance

public static <T> ThrowingSupplier<T> of(ThrowingSupplier<T> supplier)

Lambda friendly convenience method that can be used to create a 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));

Parameters

<T>: the type of results supplied by this supplier
supplier:ThrowingSupplier<T>: the source supplier

Returns:ThrowingSupplier<T>

a new ThrowingSupplier instance
