Method Detail

intGetChars

public static int intGetChars(int src,
                              char[] buf,
                              int offset)

Place a character representation of src into the buffer. No formatting (e.g. localization) is done.

Parameters:

src - - the integer to convert. Must not be Integer.MIN_VALUE.

buf - - the buf to put the result in

offset - - the offset in buf to place the first digit

Returns:

the number of bytes added to buf

Throws:

java.lang.IllegalArgumentException - if src is Integer.MIN_VALUE.

intGetBytes

public static int intGetBytes(int src,
                              byte[] buf,
                              int offset)

Place a byte representation of src into the byte array buf. No commas or any other formatting is done to the integer.

Parameters:

src - - the integer to convert. Must not be Integer.MIN_VALUE.

buf - - the buf to put the result in

offset - - the offset in buf to place the first digit

Returns:

the number of bytes added to buf

Throws:

java.lang.IllegalArgumentException - if src is Integer.MIN_VALUE.

hashCode

public static int hashCode(java.lang.String s)

Work around a performance bug in String.hashCode() for strings longer than sixteen characters, by calculating a (slower) hash on all the characters in the string. Not needed starting in the JDK 1.2 release.

wordWrap

public static java.lang.String[] wordWrap(java.lang.String msg,
                                          int widthInChars)

Word-wrap a string into an array of strings. Space is the only separator character recognized.

arrayToString

public static java.lang.String arrayToString(java.lang.String[] from,
                                             java.lang.String separator)

Convert an array of strings to a single line with elements separated by the given separator. Similar to Tcl's join.

Parameters:

from - the array of strings to convert

separator - the string to insert between each element

stringToArray

public static java.lang.String[] stringToArray(java.lang.String from,
                                               java.lang.String separator)

Convert a string of delimited strings to an array of strings. Similar to AWK's and Tcl's split.

Parameters:

from - the string to convert

separator - the delimiter

truncateFloat

public static java.lang.String truncateFloat(float f,
                                             int digits)

Truncate a float to the required number of significant digits.

addCommas

public static java.lang.String addCommas(float f)

Deprecated. Use standard java.* APIs which create the correct localized number format.

Add commas to a number for "123,456.7" style formatting.

addCommas

public static java.lang.String addCommas(java.lang.String numStr)

Deprecated. Use standard java.* APIs which create the correct localized number format.

Add commas to a number for "123,456.7" style formatting.

isSubclassOf

public static boolean isSubclassOf(java.lang.Class sub,
                                   java.lang.Class sup)

Deprecated. Use sup.isAssignableFrom(sub)

Test if a class is a subclass of another.

getSuperInterfaces

public static java.util.Set getSuperInterfaces(java.lang.ClassLoader cl,
                                               java.lang.String className,
                                               java.lang.String baseClassName)
                                        throws java.lang.ClassNotFoundException

Get all super-interfaces of a class, excluding the given base interface. Returns a set of strings containing class names.

getMethod

public static java.lang.reflect.Method getMethod(java.lang.Class declaringClass,
                                                 java.lang.ClassLoader loader,
                                                 java.lang.String name,
                                                 java.lang.String[] paramClassNames)
                                          throws java.lang.Exception
