Class Printers

java.lang.Object
  de.unkrig.commons.text.Printers

public final class Printers
extends java.lang.Object

Manages the "context printer".

Use the error(String), warn(String), info(String), verbose(String) and debug(String) methods to print to the context printer.

The default context printer prints errors and warnings to System.err and infos to System.out, and discards verbose and debug messages.

To switch to a different printer, use the withPrinter(Printer, Runnable) methods.
