Constructor Detail

DiagnosticsLoggerTeam

public DiagnosticsLoggerTeam(org.apache.avalon.framework.logger.Logger mainLogger,
                             org.apache.avalon.framework.logger.Logger diagnosticsLogger)

Constructs this object with the specified main and diagnostics logger. If no loggers are supplied then the null logger is used.

Parameters:

mainLogger - the main logger of the team

diagnosticsLogger - the diagnostics logger of the team

Method Detail

isNullLogger

protected boolean isNullLogger()

Description copied from class: AbstractLoggerTeam

Indicates if this logger team is made up of only null loggers.

Overrides:

isNullLogger in class AbstractLoggerTeam

See Also:

AbstractLoggerTeam.isNullLogger()

getMember

public org.apache.avalon.framework.logger.Logger getMember(Object tag)

Description copied from interface: LoggerTeam

Returns the memeber logger associated with the tag. This operation will always return a logger as an undefined tag is implicitly associated with a NullLogger.

Overrides:

getMember in class AbstractLoggerTeam

See Also:

LoggerTeam.getMember(Object)

createChildLoggerTeam

public LoggerTeam createChildLoggerTeam(String name)

Description copied from interface: LoggerTeam

Creates a new child LoggerTeam with the specified name. This operation has the same function as the getChildLogger operation, but avoids the need to cast to LoggerTeam.

See Also:

LoggerTeam.createChildLoggerTeam(String)

createPrefixingLoggerTeam

public LoggerTeam createPrefixingLoggerTeam()

Description copied from interface: LoggerTeam

Creates a prefixing version of this LoggerTeam.

See Also:

LoggerTeam.createPrefixingLoggerTeam()

narrow

public static LoggerTeam narrow(org.apache.avalon.framework.logger.Logger logger,
                                org.apache.avalon.framework.logger.Logger diagnosticsParent,
                                String childName)

Narrow a Logger to a LoggerTeam by either casting or wrapping in and instance of DiagnosticsLoggerTeam using the specified child logger.

Parameters:

logger - the logger to be narrowed

diagnosticsParent - the parent logger to create the child from

childName - the child name to be used

Returns:

the narrowed logger
