Class Debug

java.lang.Object

simpledb.Debug

public class Debug
extends java.lang.Object

Debug is a utility class that wraps println statements and allows more or less command line output to be turned on.

Change the value of the DEBUG_LEVEL constant using a system property: simpledb.Debug. For example, on the command line, use -Dsimpledb.Debug=x, or simply -Dsimpledb.Debug to enable it at level 0. The log(level, message, ...) method will print to standard output if the level number is less than or equal to the currently set DEBUG_LEVEL.
