Examples of java.io.PrintStream.checkError()

java.io.PrintStream.checkError()
Answers a boolean indicating whether or not this PrintStream has encountered an error. If so, the receiver should probably be closed since further writes will not actually take place. A side effect of calling checkError is that the target OutputStream is flushed. @return true if an error occurred in this PrintStream,false otherwise.

                for (String r : res) {

                if (out.checkError()) {
                  break;

              }
            } catch (IOException e) {
              console.printError("Failed with exception " + e.getClass().getName() + ":"
