HasSameContentAs()

HasSameContentAs: order-independent equality check. Two lists have the same content iff each is a permutation of the other -- same length, and every item in A appears (with the same multiplicity) in B. Walk-and-mark, O(N*M) -- fine for narrative test sizes; lift to a hash-based approach when called on large lists in real code paths.

The extensions of this method

Each extension, and whether it exists for this method; an extension that exists combines with the others (FindSTCS).

Extension

Exists

What it adds · The names

does what the method does, then returns the object, so the call can be chained

chains on the next, more specific type of object (the Q ladder)

QQQ

chains on the most specific type of object (the Q ladder)

QRT

returns the result as an object of the requested type

takes a case-sensitivity flag

takes the position to start from (StartingAt)

takes bounds that are included (IncludingBounds)

the extended form: more parameters than the base method

XTT

yet another extension: a further extended form, after XT

includes the position in what it returns

returns positions as sections, [start, end]

selects by a condition

selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)

takes a direction, forward or backward (Directional)

takes a function (the condition or the update is given as a function); the forms document also uses F for the future form, which defers the action

Many

works on a collection of items instead of one (the plural form)

Except

takes exceptions, what to leave out (the exceptional form)

returns the result without duplication

Every example is a test file of the library, run inside the library for this page; only those whose output kept every promise their file wrote are shown.
