chapter10.SimpleConfigurator
ComputationAction2 will print the result of the compuration made by children elements but only if the computation itself is named, that is if the name attribute of the associated computation element is not null. In other words, anonymous computations will not print their result. ComputationAction2 differs from ComputationAction1 in its handling of instance variables. ComputationAction1 has a simple nameStr instance variable. This variable is set when the begin() method is called and then later used within the end() method. This simple approach works properly if the begin() and end() method of a given action are expected to be called in sequence. However, there are situations where the begin() method of the same action instance is invoked multiple times before the matching end() method is invoked. When this happens, the second call to begin() overwrites values set by the first invocation to begin(). The solution is to save parameter values into a separate stack. The well-formedness of XML will guarantee that a value saved by one begin() will be consumed only by the matching end() method. Note that in the vast majority of cases there is no need to resort to a separate stack for each variable. The situation of successive begin() invocations can only occur if: 1) the associated pattern contains a wildcard, i.e. the * character and 2) the associated element tag can contain itself as a child For example, "*/computation" pattern means that computations can contain other computation elements as children. @author Ceki Gülcü
