Method Details

setOutputDirectory

public static void setOutputDirectory(String dirName,
 String mainClassName)

Graphics files are saved in directory dirName/mainClassName. dirName directory is created if it does not already exist. If dirName/mainClassName exists, then numbers are appended to the directory name: "dirName/mainClassName 1", "dirName/mainClassName 2", etc.

isWindows

public static boolean isWindows()

getDesktop

public static String getDesktop()

peekFilename

public static String peekFilename()

The name of the output file is derived from baseFilename by appending successive integers.

nextFilename

private static String nextFilename()

setBaseFilename

private static void setBaseFilename()

canTreatAsPrimitive

private static boolean canTreatAsPrimitive(Value v)

looksLikePrimitiveArray

private static boolean looksLikePrimitiveArray(ArrayReference obj)

canIgnoreObjectField

private static boolean canIgnoreObjectField(Field field)

canIgnoreStaticField

private static boolean canIgnoreStaticField(Field field)

canAppearUnquotedInLabel

private static boolean canAppearUnquotedInLabel(char c)

quote

protected static String quote(String s)

unescapeJavaString

private static String unescapeJavaString(String st)

Unescapes a string that contains standard Java escape sequences.

• \\b \\f \\n \\r \\t \\" \\' : BS, FF, NL, CR, TAB, double and single quote.
• \\N \\NN \\NNN : Octal character specification (0 - 377, 0x00 - 0xFF).
• \\uNNNN : Hexadecimal based Unicode character.

Parameters:

st - A string optionally containing standard java escape sequences.

Returns:

The translated string.
