public class SqlRecorder extends SqlLogger
Extension of SqlLogger that includes buffer for queries which can be inspected later. Information to the buffer is added regardless of the logger level setting, but can be controlled by startRecording() and stopRecording() methods. Recording is off when the SQL recorder is created, only logging works. Maximum size of the buffer is provided in the constructor, information about older queries are discarded when the buffer is full. Query buffer contains SQL string and string for each parameter formatted for the logging. For instance, it contains just a preview of very long byte array, not the original value. Logs everything on debug, including parameters as they are formatted for the buffer anyway.
