Items not described here are as in the Standard ML Basis' MONO_ARRAY_SLICE signature.
A local synonym for type slice.
Creates a vector of the elements of sl. Equivalent to vector sl.
Creates a list of the elements of sl in order of increasing indices.
Reverses in-place the order of elements in the slice sl.
Swaps the ith and jth element of slice sl. If i < 0 or |sl| <= i, or j < 0 or |sl| <= j, then the Subscript exception is raised.
These functions remove k elements from the left (respectively, right) of the slice sl. If k is greater than the size of the slice, an empty slice is returned. Specifically, for a slice sl = slice(arr,i,j) and k ≤ j, we have:
triml k sl = slice(arr, i+k, j-k) trimr k sl = slice(arr, i, j-k)
The exception Subscript is raised if k < 0. This exception is raised when triml k or trimr k is evaluated.
Returns the pair of slices (sl1, sl2), where sl1 contains the first i characters of sl and sl2 contains the rest, assuming 0 ≤ i ≤ size sl. Otherwise, it raises Subscript.
These functions scan sl from left to right (respectively, right to left) looking for the first element that does not satisfy the predicate f. They return the pair (sl1, sl2) giving the split of the slice into the span up to that element and the rest. The slice sl1 is the left side of the split, sl2the right side.
These routines scan the slice sl for the first element not satisfying the predicate f. The functions dropl and takel scan left to right (i.e., increasing indices), while dropr and taker scan from the right. The drop functions drop the maximal subslice consisting of elements satisfying the predicate, while the take functions return the maximal such subslice. These can be defined in terms of the split operations:
takel f sl = #1(splitl f sl) dropl f sl = #2(splitl f sl) taker f sl = #2(splitr f sl) dropr f sl = #1(splitr f sl)
Like app and appi, but apply f in right to left order (i.e., decreasing indices). The expression appr f sl is equivalent to:
appri (f o #2) sl
Indexed versions of the functions all and exists. The index of each element is passed to f as an additional argument. The following equivalences hold:
all f sl = alli (f o #2) sl exists f sl = existsi (f o #2) sl
Returns true if the element a occurs in the slice sl, with respect to the element equality eq; otherwise false.
Returns true if the element a does not occur in the slice sl, with respect to the element equality eq; otherwise false. Equivalent to not(contains eq sl a).
Creates an equality function on slices given an equality on the element type.
Returns true iff the elements in sl are sorted with respect to the ordering function f.
Sorts the elements in the slice sl with respect to the ordering function f. Sorting may be unstable with respect to equal elements.
