codeValueExpression (Code Value Expression)

In the Properties view, this property is the Code Value Expression property in the Bar Code category.

Property of the BARCODEBOX, which expects a PXML string expression value to calculate a page number string. When set, the value of the property overrides the codeValue property. The value of the codeValue property is still used for measuring the required space, but if it is not set the default size which is computed from the expression should be sufficiently exact.

Type: PXML.

If a value for this property, or for the X-Size property, is not set, a default length is used in calculating the page number string from these functions.

These functions can be used to format and access specific page numbers and totals.

• Class String: format(Numeric number, Enum format) - formats the number as specified. The value for the format parameter can be ARABIC, LOWERROMAN or UPPERROMAN.
• Class Numeric: getPhysicalPageNumber() - gets the current page number of the physical page.
• Class Numeric: getTotalNumberOfPhysicalPages() - gets the total number of physical pages.
• Class Numeric: getPageNumber(String pageName)- gets the page number of the specified page
• Class Numeric: getTotalNumberOfPages(String pageName) - gets the total number of pages for the specified page.

See " Page N of M" examples.
