replace

Performs a linear scan of complete array, replacing occurrences of specified element with the new element. Comparisons will be performed using the supplied predicate or '==' if none is supplied.

size_t replace(T[] array, T element, T new_element, Pred pred)
size_t replace(Buffer!(T) array, T element, T new_element, Pred pred)
size_t
replace
(
T
Pred = DefaultPredicates.IsEqual!(T)
)
(
ref Buffer!(T) array
,
in T element
,
T new_element
,
Pred pred = Pred.init
)

Parameters

array Buffer!(T): The array to scan.
element T: The pattern to match.
new_element T: The value to substitute.
pred Pred: The evaluation predicate, which should return true if e1 is equal to e2 and false if not. This predicate may be any callable type.

Return Value

Type: size_t

The number of elements replaced.

Examples

auto buffer = createBuffer("abbbbc");
test!("==")(replace(buffer, 'b', 'x'), 4);
test!("==")(buffer[], "axxxxc");

auto array = "abbbbc".dup;
test!("==")(replace(array, 'b', 'x'), 4);
test!("==")(array, "axxxxc");
