public class LogViewer
extends java.lang.Object

Warning! All classes in package palio.admin are prepared for internal use of administration panel (written in palio code so usage cases cannot be simply referenced). Any other palio code should not access this code due to possible future incompatibilities.

Every instance of LogViewer tails one log file and keeps tracking information between sequential read calls.
