Method Detail

integerFromString

public static BigInteger integerFromString(String str)
                                    throws NumberFormatException,
                                           NullPointerException

Parses the given string into a BigInteger. This method uses BigInteger.BigInteger(java.lang.String) to parse the string, but allows a optional leading '+' for positive values.

Parameters:

str - the string to be parsed.

Returns:

a BigInteger representing the same value as the string.

Throws:

NumberFormatException - if the string can not be parsed.

NullPointerException - if the string is null.

intFromString

public static int intFromString(String str)
                         throws NumberFormatException,
                                NullPointerException

Parses the given string into a int. This method uses Integer.parseInt(java.lang.String) to parse the string, but allows a optional leading '+' for positive values.

Parameters:

str - the string to be parsed.

Returns:

a int representing the same value as the string.

Throws:

NumberFormatException - if the string can not be parsed.

NullPointerException - if the string is null.

longFromString

public static long longFromString(String str)
                           throws NumberFormatException,
                                  NullPointerException

Parses the given string into a long. This method uses Long.parseLong(java.lang.String) to parse the string, but allows a optional leading '+' for positive values.

Parameters:

str - the string to be parsed.

Returns:

a long representing the same value as the string.

Throws:

NumberFormatException - if the string can not be parsed.

NullPointerException - if the string is null.

isValidToken

public static boolean isValidToken(String token)

Checks if the given string complies to the XML schema token restrictions.

XML Schema Definition: token represents tokenized strings. The value space of token is the set of strings that do not contain the carriage return (#xD), line feed (#xA) nor tab (#x9) characters, that have no leading or trailing spaces (#x20) and that have no internal sequences of two or more spaces. For more information about the XML Schema datatype definition of a token see XML Schema datatype: token

Parameters:

token - the string to be checked

Returns:

true if the given string complies to the XML schema token restrictions; false otherwise.

fromDateTimeString

public static Date fromDateTimeString(String date)

Parses the given String as schema date time representation and returns a Date object holding the given time. This method must only be used after a JAXBContext has been initialized, otherwise it is likely that a NullpointerException is thrown.

Parameters:

date - the date time in schema dateTime

Returns:

a newly generated Date object representing the time given in the date.

fromDateString

public static Date fromDateString(String date)

Parses the given String as schema date representation and returns a Date object holding the given time. This method must only be used after a JAXBContext has been initialized, otherwise it is likely that a NullpointerException is thrown.

Parameters:

date - the date in schema date representation

Returns:

a newly generated Date object representing the time given in the date.
