(metallurgy)

A converter that separates purified copper from residue in a single operation.

(programming)

selector - 1. In Smalltalk or Objective C, the syntax of a message which selects a particular method in the target object.

2. An operation that returns the state of an object but does not alter that state. Selector functions or methods often have names which begin with "get" and corresponding modifier methods or procedures whose names begin with "set".

Selector

an electromechanical device for the reception of calls in a selective telephone communication system. Selectors have been used predominantly in railroad systems. The call signal of a subscriber consists of a code, or series of electric pulses. The selector is tuned to a certain coded combination of pulses and operates—for example, rings a bell—only when the corresponding call signal is transmitted through the telephone line. In the 1960’s selector systems were supplanted by improved systems based on harmonic selective ringing. [23-S75–2]
