Method Detail

discard

public static final void discard(Object o)

discard

public static final void discard(int i)

equal

public static final boolean equal(String s0,
                                  String s1)

Returns whether two strings are equal or are both null.

clone

public static StatementList clone(StatementList e)

clone

public static String[] clone(String[] a)

clone

public static int[] clone(int[] a)

equals

public static boolean equals(int[] a,
                             int[] b)

Returns whether two integer arrays are equal. Neither must be null.

hash

public static int hash(int i,
                       int j)

main

public static void main(String[] args)
                 throws Exception

Runs the test suite.

Exception

minus

public static Set minus(Set set1,
                        Set set2)

Return a set of the elements which are in set1 but not in set2, without modifying either.

nLogN

public static double nLogN(double d)

Computes nlogn(n) (or n if n is small, so the result is never negative.

print

public static void print(PrintWriter pw,
                         Object o)

Print an object using reflection. We can handle null; arrays of objects and primitive values; for regular objects, we print all public fields.

print

public static void print(PrintWriter pw,
                         Object o,
                         int indent)

printJavaString

public static final void printJavaString(PrintWriter pw,
                                         String s,
                                         boolean nullMeansNull)

Prints a string, enclosing in double quotes (") and escaping if necessary. For examples, printDoubleQuoted(w,"x\"y",false) prints "x\"y".

println

public static void println(PrintWriter pw,
                           Object o)

replace

public static final String replace(String s,
                                   String find,
                                   String replace)

Replaces every occurrence of find in s with replace.

toURL

public static URL toURL(File file)
                 throws MalformedURLException

Creates a file-protocol URL for the given file.

MalformedURLException

clone

public static Expression clone(Expression exp)

clone

public static Expression[] clone(Expression[] a)

stripDoubleQuotes

public static String stripDoubleQuotes(String value)

Converts double-quoted Java strings to their contents. For example, "foo\"bar" becomes foo"bar.

                  throws Exception

Exception

toArray

public static Object[] toArray(Vector v)

Deprecated. use Vector.toArray() on Java2

toArray

                               Object[] a)

Equivalent to Vector.toArray(Object[]).
