Package eu.bandm.tools.message

Class MessagePrinter.Indenting<M extends Message>

java.lang.Object

eu.bandm.tools.message.MessagePrinter<M>

eu.bandm.tools.message.MessagePrinter.Indenting<M>

All Implemented Interfaces:

MessageReceiver<M>

Enclosing class:

MessagePrinter<M extends Message>

public static class MessagePrinter.Indenting<M extends Message>
extends MessagePrinter<M>

Specialization of MessagePrinter with addtional features.

• indenting of messages according to Message.Kind.logStart and Message.Kind.logEnd
• a SimpleMessage.Ping message is printed as a single character without line feed, for progress indication.
• colors can be set to highlight errors and warnings.
• the time between a logstart and corresponding logend can be printed

The string values for indentation and pinging are defined at construction time.
Error, warning and hint messages are not indented, for not disturbing their recognition by a parser, e.g. by XEmac's "next-error" function.

Constructor Details

Indenting

public Indenting(OutputStream os)

Takes default values for indent and ping string, behaves like the super constructor.

Indenting

public Indenting(PrintWriter out)

Takes default values for indent and ping string, behaves like the super constructor.

Indenting

public Indenting(OutputStream os,
 String ps,
 String is,
 boolean sst)

Indenting

public Indenting(PrintWriter out,
 String ps,
 String is,
 boolean sst)

constructor which takes explitly values for ping string and indent string. Apart from that behaves like the super constructor.
