This output shows that each invocation of a method resulted in creating a brand-new Transformer object even for the same-source stylesheet file. In the next section, you will see how you can use a caching aspect to avoid creating a new Transformer object if the stylesheet is the same. 7.5.1 AspectJ-based caching: the first version Now let s introduce caching using AspectJ. We would like to cache the Transformer instances for each source stylesheet file, and create the Transformer for tableRaw.xsl and tablePretty.xsl only once. The subsequent transformations should just reuse those instances. Extending the pooling concept, we need to surround the Transformer creation with an around advice. The advice should first check whether the cache already has a matching Transformer; if it exists, the advice should return it. Otherwise, the around advice should proceed with creating a new instance and add it to the cache before returning. We encode this logic into an aspect, as shown in listing 7.19.

And in fact we don t have to we can pass an array of numbers to a simpler overload of the Sort method, as shown in Example 7-16.
