Class FileLogger

java.lang.Object

com.couchbase.lite.FileLogger

All Implemented Interfaces:

Logger

public final class FileLogger
extends Object
implements Logger

A logger for writing to a file in the application's storage so that log messages can persist durably after the application has stopped or encountered a problem. Each log level is written to a separate file.

Threading policy: This class is certain to be used from multiple threads. As long as it, itself, is thread safe, the various race conditions are unlikely and the penalties very small. "Volatile" ensures the thread safety and the several races are tolerable.
