Interface PrecomputedValueRegistry

  • All Known Implementing Classes:
    PrecomputedValueRegistryBuilder

    public interface PrecomputedValueRegistry
    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.
