All Implemented Interfaces:

FinishableOutputStream

public class UniquePrintStream

extends PrintStream

implements FinishableOutputStream

The UniquePrintStream keeps Strings buffered in sorted order, but any duplicates are removed. This stream can be used to print error messages exactly once. When finish is called all messages are printed. It only acts on the println(String) method, any other method will print directly.
