Poor-man Cache

A simple way of caching plugin execution is shown in the PrologPlugin.

We use two tags:

• XXX for normal execution at view time
• SAVEXXX for caching at save time the execution

In commonTagsHandler:

• we handle normally the %XXX{<args>}% tag
• we visualize the cached value ( <result> ) stored in %SAVEXXX{<args> cachedvalue="<result>"}%

• we transform the %XXX{<args>}% tag to %SAVEXXX{<args> cachedvalue="<result>"}%

• we transform back the %SAVEXXX{<args> cachedvalue="<result>"}% tag to the XXX{<args>} form for edit
