Method Detail

isDebugEnabled

public boolean isDebugEnabled()

Description copied from interface: SFLogger

Is debug level enabled?

Specified by:

isDebugEnabled in interface SFLogger

Returns:

true if the trace level is DEBUG

isErrorEnabled

public boolean isErrorEnabled()

Description copied from interface: SFLogger

Is error level enabled?

Specified by:

isErrorEnabled in interface SFLogger

Returns:

true if the trace level is ERROR

isInfoEnabled

public boolean isInfoEnabled()

Description copied from interface: SFLogger

Is info level enabled?

Specified by:

isInfoEnabled in interface SFLogger

Returns:

true if the trace level is INFO

isTraceEnabled

public boolean isTraceEnabled()

Description copied from interface: SFLogger

Is trace level enabled?

Specified by:

isTraceEnabled in interface SFLogger

Returns:

true if the trace level is TRACE

isWarnEnabled

public boolean isWarnEnabled()

Description copied from interface: SFLogger

Is warn level enabled?

Specified by:

isWarnEnabled in interface SFLogger

Returns:

true if the trace level is WARN

debug

public void debug(String msg)

Specified by:

debug in interface SFLogger

debug

public void debug(String msg,
                  Object... arguments)

Description copied from interface: SFLogger

Logs message at DEBUG level.

Specified by:

debug in interface SFLogger

Parameters:

msg - Message or message format

arguments - objects that supply value to placeholders in the message format. Expensive operations that supply these values can be specified using lambdas implementing ArgSupplier so that they are run only if the message is going to be logged. E.g., Logger.debug("Value: {}", (ArgSupplier) () -> expensiveOperation());

debug

public void debug(String msg,
                  Throwable t)

Specified by:

debug in interface SFLogger

error

public void error(String msg)

Specified by:

error in interface SFLogger

error

public void error(String msg,
                  Object... arguments)

Description copied from interface: SFLogger

Logs message at ERROR level.

Specified by:

error in interface SFLogger

Parameters:

msg - Message or message format

arguments - objects that supply value to placeholders in the message format. Expensive operations that supply these values can be specified using lambdas implementing ArgSupplier so that they are run only if the message is going to be logged. E.g., Logger.warn("Value: {}", (ArgSupplier) () -> expensiveOperation());

error

public void error(String msg,
                  Throwable t)

Specified by:

error in interface SFLogger

info

public void info(String msg)

Specified by:

info in interface SFLogger

info

public void info(String msg,
                 Object... arguments)

Description copied from interface: SFLogger

Logs message at INFO level.

Specified by:

info in interface SFLogger

Parameters:

msg - Message or message format

arguments - objects that supply value to placeholders in the message format. Expensive operations that supply these values can be specified using lambdas implementing ArgSupplier so that they are run only if the message is going to be logged. E.g., Logger.info("Value: {}", (ArgSupplier) () -> expensiveOperation());

public void info(String msg,
                 Throwable t)

Specified by:

info in interface SFLogger

Specified by:

trace in interface SFLogger

Parameters:

msg - Message or message format

arguments - objects that supply value to placeholders in the message format. Expensive operations that supply these values can be specified using lambdas implementing ArgSupplier so that they are run only if the message is going to be logged. E.g., Logger.trace("Value: {}", (ArgSupplier) () -> expensiveOperation());

trace

public void trace(String msg,
                  Throwable t)

Specified by:
