stzStringCharList

44 own methods · 5 forms written with extensions, listed under their method

also named: stzListOfChars

the source: base/string/stzStringCharList.ring(opens in a new tab) · All classes · The area reference: String

Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean

Examples: 0 come from the library's tests; 27 were composed from each method's signature and run for this page, on a fresh object, for example o1 = new stzStringCharList("hello"). 17 methods have none yet. Examples run on 2026-10-03 20:23 inside the library at commit 0e72e2e2c.
