public class Util

extends java.lang.Object

Field Summary

static java.lang.String	DATE_FORMAT_AM_PM
static java.lang.String	DATE_FORMAT_CANONICAL Deprecated. Will become a private constant since this doesn't handle parsing a general IS0-8601 format. (Only handles our subset). Instead always use the public methods stringToDate and getCanonicalDateString. (At some point we may want to handle parsing a general IS0-8601 format).
static java.lang.String	DATE_FORMAT_COMPACT Year-month-day with twenty-four-hour time: "yyyyMMdd HH:mm:ss"
static java.lang.String	DATE_FORMAT_DEFAULT
static java.lang.String	DATE_FORMAT_MILLIS Timestamp in milliseconds (a stringified Java long value).

Method Detail

isNumeric

public static boolean isNumeric(java.lang.String s)

Parameters:

s - string

Returns:

true if the specified string contains only digits or decimal points, and possibly a leading minus sign. Cheaper than catching an exception from a parse method.

stringToDate

public static java.util.Date stringToDate(java.lang.String src)
                                   throws java.text.ParseException

Convert the string representation for a date into a Date object. The string may be of the following forms: M/d/y H:m:s z M/d/y H:m:s M/d/y yyyyMMdd HH:mm:ss (default) yyyyMMdd HH:mm:ss.SSS (old canonical) yyyyMMddTHH:mm:ss.SSS (old canonical absolute) yyyy-MM-ddTHH:mm:ss.SSSZ (canonical, no offset) yyyy-MM-ddTHH:mm:ss.SSS+/-HHMM (canonical, offset) nnnnnnnnnnnnnnnnn (milliseconds)

Throws:

java.text.ParseException

See Also:

Util.DATE_FORMAT_COMPACT, Util.DATE_FORMAT_DEFAULT, Util.DATE_FORMAT_MILLIS

dateToString

public static java.lang.String dateToString(java.util.Date src)

Format a Date value as a String, using the usual "American" format with the current time zone. NOTE: The "American" format doesn't sort worth a damn.

decodeCommaString

public static java.util.List decodeCommaString(java.lang.String src)

Parse a comma delimited string into a List of strings.

Parameters:

src - comma separated list of values

Returns:

list of values

decodeCommaString

public static java.util.List decodeCommaString(java.lang.String src,
                                               boolean filterEmpty)

dateToString

public static java.lang.String dateToString(java.util.Date date,
                                            java.lang.String simpleDateFormatPattern)

Returns:

a string representing a specified date in the specified format.

getCanonicalDateString

public static java.lang.String getCanonicalDateString(java.util.Date date,
                                                      java.util.TimeZone timeZone)

Returns:

An IS0-8601 formatted date string

lpad

public static java.lang.String lpad(java.lang.String str,
                                    int length)

Left-pad a string to the specified length. Pad a numeric string with zeros, any other with the space character.

Parameters:

str - string

length - length for padded string

Returns:

left padded string

Util.isNumeric(String)

lpad

public static java.lang.String lpad(java.lang.String str,

                                    char padChar)

Left-pad a string to the specified length with the specified character.

Parameters:

str - string

length - length for pad

padChar - character to use for padding

Returns:

padded string

pad

public static java.lang.String pad(java.lang.String s,
                                   int len,
                                   char pad,

Parameters:

v - number or string representation of a number

Returns:

int value, possibly truncated, of v

itoa

public static java.lang.String itoa(int i)

Convert an primitive integer value into a String. This doesn't really save much space, but its the obvious inverse to atoi.

Parameters:

i - integer

Returns:

String representation of i

flattenList

public static void flattenList(java.util.List inList,
                               java.util.List retList)

Flatten out an input list that may contain list entries. Flattened list is contained in retList No entries are removed from retList. Only new non-List entities are added.

Parameters:

inList -

retList -

isPath

public static boolean isPath(java.lang.String s)

Determine if string is a path. It is a path if it contains a '.' or '[' character. This was done to replace 2 indexOf() calls which were found to be taking a significant amount of time for some scenarios

Parameters:

s -

Returns:

true if a path, false otherwise

splitPathAroundLastDot

public static void splitPathAroundLastDot(java.lang.String tmpPath,
                                          java.lang.StringBuilder sbVo,
                                          java.lang.StringBuilder sbAttr)

Divide up a path based on the last '.' in the path. sbVo will contain everything to the left and sbAttr will contain everything to the right If path does not have any '.' characters then entire path is put into sbVo
