set(delimiters)
delimiters
Sets a new record boundary. The delimiters parameter is an offset from the current delimiter,
expressed in an integer that represents a number of delimiters.
If this parameter is not specified, then a value of 0 is assumed. A value of 0 indicates the
record boundary occurs on the current delimiter.
A negative value of -n indicates that the record boundary occurred -n delimiters before the
current delimiter.
A positive value of n indicates that the record boundary occurs +n delimiters after the current
delimiter.
Note
Specifying a positive value not only sets the DataMapper record boundary but it also advances the
current delimiter to the specified delimiter. That's where the processing resumes. This allows you to
skip some pages/records when you know they do not need to be examined. Negative (or 0) values
simply set the boundary without changing the current location.
Example
This script sets a boundary when the text TOTALis found on the current page in a PDFfile.
The number of delimiters is set to 1, so the boundary is set on the next delimiter, which is the
start of the next page.
if (boundaries.find("TOTAL", region.createRegion
(10,10,215,279)).found) {
boundaries.set(1);
}
Assume you want to set record boundaries whenever the text "TOTAL" appears in a specific
region of the page of a PDF file, but the PDF file has already been padded with blank pages for
duplexing purposes. The boundary should therefore be placed at the end of the page where the
match is found if that match occurs on an even page, or at the end of the next blank page, if the
match occurs on an odd page. Recall that for PDF files, the natural delimiter is a PDF page.
The JavaScript code would look something like the following:
var myRegion = region.createRegion(150,220,200,240);
if(boundaries.find("TOTAL", myRegion).found) {
/* a match was found. Check if we are on a odd or even page and
