Method Detail

compareTo

public static int compareTo(Comparable a,
                            Object b)

Compare two objects allowing null. Null is ordered low.

compareTo

public static int compareTo(int a,
                            int b)

compareTo

public static int compareTo(short a,
                            short b)

enum2Iterator

public static final Iterator enum2Iterator(Enumeration enum)

Turn an Enumeration into an Iterator.

Enumeration, Iterator, Collections.enumeration(Collection)

iter2Collection

public static final Collection iter2Collection(Collection coll,
                                               Enumeration iter)

Turn an Iterator into a Collection.

iter2Collection

public static final Collection iter2Collection(Enumeration iter)

Turn an enumeration into a Collection.

iterator2Collection

public static final Collection iterator2Collection(Collection coll,
                                                   Iterator iter)

Turn an Iterator into a Collection.

iterator2Collection

public static final Collection iterator2Collection(Iterator iter)

Turn an Iterator into a Collection.

keyForValue

public static Object keyForValue(Map map,
                                 Object value)
                          throws NoSuchElementException

NoSuchElementException

putAll

public static void putAll(Dictionary dest,
                          Dictionary src)

Provides a putAll implementation for Java1.

split

public static final String[] split(String src,
                                   String delimiter)

Split a String into a String[] using the StringTokenizer. Works on any type of delimiter, including ''.

StringTokenizer

throwable2String

public static String throwable2String(Throwable ex)

toBinaryString

public static final String toBinaryString(int value,
                                          int pad)

Format the integer to a padded binary string.
