Interface ConsumerExt<T,E extends java.lang.Throwable>
-
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@PrimaryRequirement(updates=java.util.function.Consumer.class) @FunctionalInterface public interface ConsumerExt<T,E extends java.lang.Throwable>
Changes for
ConsumerWhy:
1. If a Consumer lambda throws a checked exceptions, the developer has to messily wrap it in a RuntimeException.
2. If Consumer.accept throws a RuntimeException, the compiler will not warn the developer.
3. This class provides type-safe exceptions which is not currently possible with java.util.function classes.
To eliminate the need for this class:
1. Java should support default values for generic parameters.
2. Modifyjava.util.function.Consumer<T>toConsumer<T, E extends Throwable = Throwable>
Risk:
1. Maintains source compatibility because the E parameter can be omitted.
2. Maintains binary compatibility because generic types are erased.
3. Impact on code using Reflection APIs should be minimal.
