Javadoc

Returns the cache of expression evaluation artifacts.

This cache is meant to store artifacts of diverse nature needed along the process of parsing and executing expressions in the several languages available: Standard expressions, OGNL expressions, Spring EL expressions...

Parsing these expressions usually results in some kind of syntax tree object that represents the expression, and this is what this cache usually stores.

Keys are the expressions themselves (their String representation), along with a type that is normally used for identifying the nature of the object being cached (for example {"ognl","person.name"}}).
