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