Constructor Detail

NFDebug

public NFDebug()

Method Detail

getOptions

public static java.util.Hashtable getOptions()

Returns a static hashtable containing the String names of all debug options as the key, and the numeric id as the value.

Returns:

The options.

set

public static void set(long type)

Enable the given type(s) for subsequent output. The type may be composed of OR'd type values to set multiple types at one time.

Parameters:

type - The debug option to set.

set

public static void set(java.lang.String list)

Enable the given options for subsequent output as defined in the comma separated list of option names.

Parameters:

list - A list of debug options.

set

public static void set(java.util.Vector v)

Enable all of the types defined in the given vector. The vector should contain Number objects, which will be converted to a long value to determine the bit setting. This method is generally used in conjunction with the defineDebug() method.

Parameters:

v - The list of debug options to set.

clear

public static void clear(long type)

Disable the given type(s) for subsequent output. The type may be composed of OR'd type values to clear multiple types.

Parameters:

type - The debug option to unset.

clear

public static void clear(java.lang.String list)

Clear the given options for subsequent output as defined in the comma separated list of option names.

Parameters:

list - A list of debug options.

clear

public static void clear(java.util.Vector v)

Clear all of the types defined in the given vector. The vector should contain Number objects, which will be converted to a long value to determine the bit setting.

Parameters:

v - The debug options to unset.

enabled

public static boolean enabled(long type)

Returns true if one or more of the types specified by the OR'd type parameter are currently set.

Parameters:

type - The debug option to check.

print

public static void print(java.lang.String msg)

Print the message on the current printStream, without checking for type settings.

Parameters:

msg - The message to print.

print

public static void print(long type,
                         java.lang.String msg)

Print the message on the current printStream, if the given type(s) is set.

Parameters:

type - The option.

msg - The message to print.

print

public static void print(java.io.PrintStream ps,
                         java.lang.String str)

Print the message on the given printStream.

Parameters:

ps - The stream.

str - The message to print.

exception

public static void exception(java.lang.Exception e)

Print the exception to the default printStream and notify observers.

Parameters:

e - The exception.

exception

public static void exception(java.lang.String summary,
                             java.lang.Exception e)

Print the exception to the default printStream and notify observers.

Parameters:

summary - Text to summarize the exception.

e - The exception.

exception

public static void exception(java.io.PrintStream ps,
                             java.lang.String summary,
                             java.lang.Exception e)

Print the exception to the given printStream and notify observers.

Parameters:

ps - The stream.

summary - Text to summarize the exception.

e - The exception.

warning

public static void warning(java.lang.Object warning)

Print the exception to the default printStream and notify observers.

Parameters:

warning - The warning. Note that the warning's "toString" method will be called to write to the print stream. This allows custom objects to be passed along to observers

warning

public static void warning(java.io.PrintStream ps,
                           java.lang.Object warning)

Print the exception to the given printStream and notify observers.

Parameters:

ps - The stream.

warning - The warning. Note that the warning's "toString" method will be called to write to the print stream. This allows custom objects to be passed along to observers

information

public static void information(java.lang.Object information)

Print the exception to the default printStream and notify observers.

Parameters:

information - The information. Note that the information's "toString" method will be called to write to the print stream. This allows custom objects to be passed along to observers
