Overview

Arithmetic builders shared by symbols, qualified columns and expressions. Imported into the Symbol refinement like Predications, so every method must be defined with def.

Instance Method Details

#&(other) ⇒ Object

SQL's bitwise operators. & and | are AND and OR between conditions and are defined there, which is what leaves them free to mean here what SQL means by them. Ruby's precedence puts all six above the comparisons, so :flags & 4 > 0 groups the way it reads.
