Class Debug
public class Debug
extends java.lang.Object
This class provides methods for determining where debugging output should be
sent, and what level of debugging is enabled for specific classes and
algorithms. Debugging levels are set in the
Cryptix.properties
file.

GLOBAL_DEBUG
public static final boolean GLOBAL_DEBUG
Whether to compile the library with a standard level of debugging
support.
After changing this field, all classes should be recompiled
in order to make sure that the change has taken effect.
- true
GLOBAL_DEBUG_SLOW
public static final boolean GLOBAL_DEBUG_SLOW
Whether to compile the library with additional debugging support that
is likely to slow it down.
After changing this field, all classes should be recompiled
in order to make sure that the change has taken effect.
- false
GLOBAL_TRACE
public static final boolean GLOBAL_TRACE
Whether to compile the library with tracing support or not.
After changing this field, all classes should be recompiled in order
to make sure that the change has taken effect.
- true
getLevel
public static int getLevel(String label)
Returns the debug level for
label. This is normally
given by the numeric provider property
"
Debug.Level.label
".
If this property is not set, "
Debug.Level.*
" is
searched next. If neither property is set, or if the first property
found is not a valid decimal integer, then this method returns 0.
getLevel
public static int getLevel(String label1,
String label2)
Returns the maximum of the debug levels for label1 and label2.
getOutput
public static PrintWriter getOutput()
Returns the PrintWriter to which debugging output is to be sent.
isTraceable
public static boolean isTraceable(String label)
Return true if tracing is requested for a given class.
User indicates this by setting the tracing
boolean
property for
label in the
Cryptix.properties
file. The property's key is "
Trace.label
".
label
- The name of a class.
- True iff a boolean true value is set for a property with
the key
Trace.label
.
