Class NOPRINT

  • All Implemented Interfaces:
    java.lang.Appendable
    public class NOPRINT
extends java.lang.Object
implements java.lang.Appendable
    Appendable Implementation:
    This class implements and upgrades the Simple, Java java.lang.Appendable interface, providing additional features and improvements to it. The Appendable interace is a viable design-decsion possibility for outputing text-data to a log.

    An Appendable is both blindingly easy, and highly customizable to use for third-party developers who may not be familiar with the internals of another developer's source-code.

    This Class' Primary Addition to Appendable:
    Simply allows the user to provide a 'Deaf Appendable' to code that requires a non-null instance of Appendable. This class has no public constructors, and provides, instead, a singleton instance that simply ignores all character-data that it receives via its append(...) methods.

    Note that this class is no longer used in the Java-HTML JAR.
    This class is used to shunt text-output sent to a Java Appendable; note that this Appendable can be tapped, allowing for saving text-output, without printing it. This class acts as a dummy output instance of java.lang.Appendable. It does not print any actual text, either to external output (terminal-output), nor to internal StringBuffer's.

    This class does not have any externalized (public) constructors. Instead, a public, static, final, 'singleton' field-instance of this class is available. Please see field 'np'.
