public final class ConsoleAppender
extends AbstractOutputStreamAppender<OutputStreamManager>

ConsoleAppender appends log events to System.out or System.err using a layout specified by the user. The default target is System.out. TODO accessing System.out or .err as a byte stream instead of a writer bypasses the JVM's knowledge of the proper encoding. (RG) Encoding is handled within the Layout. Typically, a Layout will generate a String and then call getBytes which may use a configured encoding or the system default. OTOH, a Writer cannot print byte streams.

                                                           String ignore)
Create a Console Appender.

layout - The layout to use (required).
filter - The Filter or null.
targetStr - The target ("SYSTEM_OUT" or "SYSTEM_ERR"). The default is "SYSTEM_OUT".
follow - If true will follow changes to the underlying output stream.
name - The name of the Appender (required).
ignore - If "true" (default) exceptions encountered when appending events are logged; otherwise they are propagated to the caller.
The ConsoleAppender.
