java.util.concurrent: public interface: Callable

java.util.concurrent
public interface: Callable [javadoc | source]

All Known Implementing Classes:
RunnableAdapter, PrivilegedCallable, CompilationTask, PrivilegedCallableUsingCurrentClassLoader

A task that returns a result and may throw an exception. Implementors define a single method with no arguments called call.

The Callable interface is similar to java.lang.Runnable , in that both are designed for classes whose instances are potentially executed by another thread. A Runnable, however, does not return a result and cannot throw a checked exception.

The Executors class contains utility methods to convert from other common forms to Callable classes.

Parameters:

< - V> the result type of method call
