Method Detail

isTraceable

public static boolean isTraceable(java.lang.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".

Parameters:

label - The name of a class.

Returns:

True iff a boolean true value is set for a property with the key Trace.label.

getLevel

public static int getLevel(java.lang.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(java.lang.String label1,
                           java.lang.String label2)

Returns the maximum of the debug levels for label1 and label2.

getOutput

public static java.io.PrintWriter getOutput()

Returns the PrintWriter to which debugging output is to be sent.
