All known Subclasses: org.jfree.report.data.PrecomputedValueRegistryBuilder,
| PrecomputedValueRegistry | | public interface PrecomputedValueRegistry (Code) | | Expression precomputation processes the report in a parallel process to
retrieve the final value of an function. The final value of an expression
is the value the expression would return before it goes out of scope.
Precomputation can be generally considered expensive, so it should be done
only once. During the precomputation run, no output is generated at all.
Only named data-row expressions can be precomputed.
