Iterator in modern Java: traversing an aggregate without exposing it, and choosing between Iterator, Stream and Spliterator — external pull versus internal lazy pipeline versus the parallel decomposition primitive. Covers when a Spliterator can adapt to both, what fail-fast really promises and how weakly consistent iterators differ, streams that hold a resource and must be closed, remote pagination as iteration with page drift, and the characteristics that decide whether a stream can be sized…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Iterator ## Purpose Let a caller walk a sequence without knowing how it is stored, and without the sequence handing out its internals. The pattern is so thoroughly absorbed into Java — `Iterable`, the enhanced `for`, `Stream` — that the design question is almost never "should we have an iterator" but "which of the three abstractions should this type expose, and what does each promise". Inspect compiler release/toolchains, source ownership, null/mutation contracts and resource lifetime before choosing. Examples use Java 17 (partial domain types/imports omitted); Gatherers are standard in Java 24 ([JEP 485](https://openjdk.org/jeps/485)) and are optional, not a reason to upgrade a target project. Start with ordinary traversal, an advanced consumer such as interleaved passes, and an early-exit or failure path. Inspect existing callers and provider contracts for replay, order, mutation and ownership before asking about gaps. Keep an adequate loop, collection view or iterator; add a new abstraction only for a required consumer capability. ## Iterator, Stream, Spliterator ```text Iterator<T> external, pull. The caller controls the pace and may …

How to install
mdr add robsonkades/agent-skills/gof-iterator@sha256:3168caadaaaf253cThe line at the top of this page pins the label git:20260927.9ecadfd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
