Constructor Detail

SLF4JExoLog

public SLF4JExoLog(org.slf4j.Logger logger)
            throws IllegalArgumentException

Create a new instance.

Parameters:

logger - Logger

Throws:

IllegalArgumentException - if the logger is null

Method Detail

isDebugEnabled

public boolean isDebugEnabled()

Description copied from interface: Log

Is debug logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than debug.

Specified by:

isDebugEnabled in interface Log

Returns:

true if debug is enabled in the underlying logger.

isErrorEnabled

public boolean isErrorEnabled()

Is error logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than error.

Specified by:

isErrorEnabled in interface Log

Returns:

true if error is enabled in the underlying logger.

isFatalEnabled

public boolean isFatalEnabled()

Is fatal logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than fatal.

Specified by:

isFatalEnabled in interface Log

Returns:

true if fatal is enabled in the underlying logger.

isInfoEnabled

public boolean isInfoEnabled()

Is info logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than info.

Specified by:

isInfoEnabled in interface Log

Returns:

true if info is enabled in the underlying logger.

isTraceEnabled

public boolean isTraceEnabled()

Is trace logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than trace.

Specified by:

isTraceEnabled in interface Log

Returns:

true if trace is enabled in the underlying logger.

isWarnEnabled

public boolean isWarnEnabled()

Is warn logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than warn.

Specified by:

isWarnEnabled in interface Log

Returns:

true if warn is enabled in the underlying logger.
