Examples of org.apache.commons.digester.SetNextRule

org.apache.commons.digester.SetNextRule

Rule implementation that calls a method on the (top-1) (parent) object, passing the top object (child) as an argument. It is commonly used to establish parent-child relationships.

This rule now supports more flexible method matching by default. It is possible that this may break (some) code written against release 1.1.1 or earlier. See {@link #isExactMatch()} for more details.

Note that while CallMethodRule uses commons-beanutils' data-conversion functionality (ConvertUtils class) to convert parameter values into the appropriate type for the parameter to the called method, this rule does not. Needing to use ConvertUtils functionality when building parent-child relationships is expected to be very rare; however if you do need this then instead of using this rule, create a CallMethodRule specifying targetOffset of 1 in the constructor.
