- 
 public class SetNextRule extends Rule 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 isExactMatch()for more details.

Constructor Detail- 
SetNextRulepublic SetNextRule(java.lang.String methodName, java.lang.String paramType)Construct a "set next" rule with the specified method name.- Parameters:
- methodName- Method name of the parent method to call
- paramType- Java class of the parent method's argument (if you wish to use a primitive type, specify the corresponding Java wrapper class instead, such as- java.lang.Booleanfor a- booleanparameter)

Method Detail- 
isExactMatchpublic boolean isExactMatch() Is exact matching being used. This rule uses org.apache.commons.beanutils.MethodUtilsto introspect the relevant objects so that the right method can be called. Originally,MethodUtils.invokeExactMethodwas used. This matches methods very strictly and so may not find a matching method when one exists. This is still the behaviour when exact matching is enabled.When exact matching is disabled, MethodUtils.invokeMethodis used. This method finds more methods but is less precise when there are several methods with correct signatures. So, if you want to choose an exact signature you might need to enable this property.The default setting is to disable exact matches. - Returns:
- true iff exact matching is enabled
- Since:
- Digester Release 1.1.1
 
 - 
setExactMatchpublic void setExactMatch(boolean useExactMatch) Set whether exact matching is enabled. See isExactMatch().- Parameters:
- useExactMatch- should this rule use exact method matching
- Since:
- Digester Release 1.1.1
 
 - 
endpublic void end(java.lang.String namespace, java.lang.String name) throws java.lang.ExceptionProcess the end of this element.- Overrides:
- endin class- Rule
- Parameters:
- namespace- the namespace URI of the matching element, or an empty string if the parser is not namespace aware or the element has no namespace
- name- the local name if the parser is namespace aware, or just the element name otherwise
- Throws:
- java.lang.Exception- if an error occurs while processing the event
