Javadoc

Utility class that splits calls to #invoke(Object) into calls to #fork(Object) or #call(Object)depending on the max number of reentrant calls to #invoke(Object).

This class prevents StackOverflowErrors in case of methods that end up invoking themselves, such is common for Callback#succeeded().

Typical use case is:

 
public void reentrantMethod(Object param) 
{ 
if (condition || tooManyReenters) 
fork(param) 
else 
call(param) 
}

Calculating tooManyReenters usually involves using a ThreadLocal and algebra on the number of reentrant invocations, which is factored out in this class for convenience.

The same code using this class becomes:

 
private final ForkInvoker invoker = ...; 
public void reentrantMethod(Object param) 
{ 
invoker.invoke(param); 
}

Most used methods

call
Executes the direct, non-forked, invocation
condition
Subclasses should override this method returning true if they want #invoke(Object) to call #fork(Obj
fork
Executes the forked invocation
invoke
Invokes either #fork(Object) or #call(Object). If #condition() returns true, #fork(Object) is invoke
