| Method Summary | |
| public static Boolean | booleanValue(String convertToBoolean)
This method works like Boolean.valueOf, but allows
null values without an exception, and also translates the
string "on" as true which is useful for
converting request values.
Parameters:
convertToBoolean - a String to be converted to a boolean value. | | public static String | generateRandomString(int length)
Generates a random string of specified length, when the length 0 or less,
defaults to 8 The string only consists of letters and numbers and the
first character is always a letter.
Parameters:
length - the length of the string to generate. | | public static String | getNotNull(Object check)
If the string supplied is not null, return the string,
otherwise return the empty string. | | public static String | getNotNull(Object check, String nullString)
Handle null objects in a standard way. | | public static Integer | integerValue(String convertToInteger)
This method works like Integer.valueOf, but allows
null values without an exception.
Parameters:
convertToInteger - a String to be converted to an integer number.null Strings return in a nullIntegerreturned. | | public static boolean | isNullOrEmpty(String checkString)
This method does just what it says: evaluates the String you give it and
returns true if it is null or an empty
string.
Parameters:
checkString - the string to check for being null or empty. | | public static String | toString(Integer convert)
Works like the standard Integer.toString() except that it
allows null values, returning a null string
in this case.
Parameters:
convert - the Integer you want to convert to a string. |
| booleanValue | | public static Boolean booleanValue(String convertToBoolean)(Code) | |
This method works like Boolean.valueOf, but allows
null values without an exception, and also translates the
string "on" as true which is useful for
converting request values.
Parameters:
convertToBoolean - a String to be converted to a boolean value. nullStrings return in a nullBoolean returned. null if convertToBoolean isnull or if convertToBoolean equalsthe string "null". It returns aBoolean true value if the string is equal to"true" or "on" (ignoring case),otherwise a Booleanfalse value is returned. |
| generateRandomString | | public static String generateRandomString(int length)(Code) | |
Generates a random string of specified length, when the length 0 or less,
defaults to 8 The string only consists of letters and numbers and the
first character is always a letter.
Parameters:
length - the length of the string to generate. a random string of the specified length. |
| getNotNull | | public static String getNotNull(Object check, String nullString)(Code) | |
Handle null objects in a standard way. If the object you pass is null,
then the string nullString will be returned.
Parameters:
check - an object to compare against null
Parameters:
nullString - the string to return if o is null the parameter nullString if o is null, otherwise o.toString()
See Also: StringHandling.getNotNull(Object check) |
| integerValue | | public static Integer integerValue(String convertToInteger)(Code) | |
This method works like Integer.valueOf, but allows
null values without an exception.
Parameters:
convertToInteger - a String to be converted to an integer number.null Strings return in a nullIntegerreturned. null if convertToInteger isnull or if convertToInteger equalsthe string value "null", otherwise an integer representing thebase 10 value of convertToInteger.
See Also: java.lang.Integer.valueOf(String convertToInteger) |
| isNullOrEmpty | | public static boolean isNullOrEmpty(String checkString)(Code) | |
This method does just what it says: evaluates the String you give it and
returns true if it is null or an empty
string.
Parameters:
checkString - the string to check for being null or empty. true if checkString isnull or an empty string |
| toString | | public static String toString(Integer convert)(Code) | |
Works like the standard Integer.toString() except that it
allows null values, returning a null string
in this case.
Parameters:
convert - the Integer you want to convert to a string. null if the integer convert. isnull, otherwise the string equivalent ofconvert. |
