wc_get_logger() │ WC 1.0

Get a shared logger instance.

Use the woocommerce_logging_class filter to change the logging class. You may provide one of the following:

- a class name which will be instantiated as `new $class` with no arguments
- an instance which will be used directly as the logger

In either case, the class or instance must implement WC_Logger_Interface.

Return

WC_Logger_Interface.
