Interface Plumbable

All Superinterfaces:

java.lang.Runnable

public interface Plumbable
extends java.lang.Runnable

is an interface for a Runnable which wants to have set an input stream to read from and/or an output stream to write to before it is run.

It is expected, that classes implementing this interface will read from an input stream, write to an output stream or do both in their run() method. The point of having the set-functions instead of specifying the streams in the constructor of such a class is that objects of the class can be created and passed around to only later have the stream(s) sepcified.

Method Detail

setOut

void setOut(java.io.OutputStream out,
            boolean closeOnExit)

setIn

void setIn(java.io.InputStream in,
           boolean closeOnExit)

getException

java.lang.Exception getException()

returns an exception which happend in the run()-method, if any.

Because input and output may cause exceptions while the run-method can not throw anything, an implementing class must have this function which allows it to return an exception which might happen during run().
