ReplaceSection()
ReplaceSection: the section [n1..n2] is replaced by ONE new item -- -- if that item is a list, it is inserted as a SINGLE element. This is -- the canonical Softanza semantics (see ReplaceSectionByMany to splice).
Basic examples (2)
Softanza
o1 = new stzList([ "1", "2", "_", "_", "_", "4", "5" ]) o1.ReplaceSection(3, 5, :With = "3") ? @@( o1.Content() )
Output
[ "1", "2", "3", "4", "5" ]

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
Q
yes
does what the method does, then returns the object, so the call can be chained · ReplaceSectionQ
QQ
no
chains on the next, more specific type of object (the Q ladder)
QQQ
no
chains on the most specific type of object (the Q ladder)
QRT
no
returns the result as an object of the requested type
CS
no
takes a case-sensitivity flag
ST
no
takes the position to start from (StartingAt)
IB
no
takes bounds that are included (IncludingBounds)
XT
no
the extended form: more parameters than the base method
XTT
no
yet another extension: a further extended form, after XT
Z
no
includes the position in what it returns
ZZ
no
returns positions as sections, [start, end]
W
no
selects by a condition
WF
no
selects by a condition, with the expressive keywords (@NextItem, @PreviousItem...)
D
no
takes a direction, forward or backward (Directional)
F
no
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
no
works on a collection of items instead of one (the plural form)
Except
no
takes exceptions, what to leave out (the exceptional form)
U
no
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.
