debug

void debug(String msg)

debug

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

Logs message at DEBUG level.

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

void debug(String msg,
           Throwable t)

error

void error(String msg)

error

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

Logs message at ERROR level.

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

void error(String msg,
           Throwable t)

info

void info(String msg)

info

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

Logs message at INFO level.

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());

info

void info(String msg,
          Throwable t)

trace

void trace(String msg)

trace

void trace(String msg,
           Object... arguments)
