In the domain of computer science, specifically within the theoretical framework of sequence data structures and algorithmic processing, an iterable object is formally defined as an entity adhering to the iterator protocol or the sequence protocol that permits sequential access to its constituent elements. This concept operates under the mechanism of lazy evaluation and stateful progression, where iteration continues until a termination condition—often signaled by a sentinel value or exhaustion of internal state—is met. As a fundamental subfield of data structure theory, this principle establishes the necessary conditions for higher-order functions to consume heterogeneous collections without requiring random access capabilities.
