Method Detail

isDebugEnabled

boolean isDebugEnabled()

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.

Returns:

true if debug is enabled in the underlying logger.

isErrorEnabled

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.

Returns:

true if error is enabled in the underlying logger.

isFatalEnabled

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.

Returns:

true if fatal is enabled in the underlying logger.

isInfoEnabled

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.

Returns:

true if info is enabled in the underlying logger.

isTraceEnabled

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.

Returns:

true if trace is enabled in the underlying logger.

isWarnEnabled

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.

Returns:

true if warn is enabled in the underlying logger.
