Package org.apache.calcite.interpreter

@DefaultQualifier(value=org.checkerframework.checker.nullness.qual.NonNull.class,locations=FIELD) @DefaultQualifier(value=org.checkerframework.checker.nullness.qual.NonNull.class,locations=PARAMETER) @DefaultQualifier(value=org.checkerframework.checker.nullness.qual.NonNull.class,locations=RETURN) package org.apache.calcite.interpreter

Provides an implementation of relational expressions using an interpreter.

The implementation is not efficient compared to generated code, but preparation time is less, and so the total prepare + execute time is competitive for queries over small data sets.
