Returns the previous element in the DtpSplitString object.
Syntax
String prevElement()
Return values
Returns a String containing the previous element.
Exceptions
DtpNoElementAtPositionException - If there is no previous element.
Notes
You can use prevElement(), along with nextElement(), to navigate the elements (tokens) in a DtpSplitString object. The first time you call nextElement(), the element position is zero. Subsequent calls to nextElement()increment the position by one. The prevElement() method returns the previous element and decrements the element position by one.
Examples
// Create a DtpSplitString object DtpSplitString MyString = new DtpSplitString("This,is a test",", "); // This call returns element 0 containing "This" String firstElement = MyString.nextElement() // This call returns element 1 containing "is" String secondElement = MyString.nextElement() // This call returns element 0 containing "This" String anotherElement = MyString.prevElement()
