Performs a linear scan of the complete array, replacing elements where pred returns true.

size_t replaceIf(T[] array, T new_element, Pred pred)
size_t replaceIf(Buffer!(T) array, T new_element, Pred pred)
size_t
replaceIf
(
T
Pred
)
(
ref Buffer!(T) array
,
T new_element
,
Pred pred
)

Parameters

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

Return Value

Type: size_t

The number of elements replaced.

Examples

auto array = "abbc".dup;
test!("==")(replaceIf(array, 'x', (char c) { return c > 'a'; }), 3);
test!("==")(array, "axxx");

auto buffer = createBuffer("abbc");
test!("==")(replaceIf(buffer, 'x', (char c) { return c > 'a'; }), 3);
test!("==")(buffer[], "axxx");
