RedirectOutputHandler

public RedirectOutputHandler(LoggerClass logger,
                             Method loggingMethod)

Create a redirect handler, with a logging class, ignoring logging levels.

Parameters:

logger - The class to use for logging. For example, java.util.logging.Logger

loggingMethod - A method which takes a *single* String argument and logs that string using the |logger| class.

RedirectOutputHandler

public RedirectOutputHandler(LoggerClass logger,
                             Method loggingMethod,
                             Map<Object,ChannelEquivalent> channelMapping,
                             ChannelEquivalent defaultChannel)

Create a redirect handler, with a logging class, redirecting both the logging message, and the channel that it came from

Parameters:

logger - The class to use for logging. For example, java.util.logging.Logger

loggingMethod - A method which takes a *single* String argument and logs that string using the |logger| class.

channelMapping - The mapping from Redwood channels, to the native Channel equivalent.

Method Detail

print

public void print(Object[] channels,
                  String line)

Description copied from class: OutputHandler

Print a string to an output without the trailing newline. Many output handlers can get by with just implementing this method.

Specified by:

print in class OutputHandler

Parameters:

channels - The channels this message was printed on; in most cases an implementing handler should not have to do anything with this. The channels should not be printed here. The channels may be null.

line - The string to be printed.

formatChannel

protected boolean formatChannel(StringBuilder b,
                                String channelStr,
                                Object channel)

Ensure that we don't print duplicate channels when adapting to another logging framework.

Overrides:

formatChannel in class OutputHandler

Parameters:

b - The StringBuilder to append to

channelStr - The [possibly truncated and/or modified] string to actually print to the StringBuilder

channel - The original channel

Returns:

|true| if the channel was printed (that is, appended to the StringBuilder)
