each multimethod

Methods

each(mm:MultiMethod, cb:Fun) Source: stdlib.ngs:137

Call cb for each method of the MultiMethod

Example

echo.each(F(method) echo("${method.params().name.join(", ")}"))

each(al:ArrLike, cb:Fun) Source: stdlib.ngs:666

Call cb for each element in the underlying array.

each(hl:HashLike, cb:Fun) Source: stdlib.ngs:721

Iterate over keys and values.

Returns

hl

Example

my_hashlike.each(F(k, v) echo("$k=$v"))

each(r:NumRange, cb:Fun) Source: stdlib.ngs:1215

Iterates over the elements of r, passing each in turn to cb.

Parameters

cb	Function to be called with values from r

Returns

r

Example

s=0
(1...10).each(F(i) { global s; s+=i })
echo(s)  # Outputs: 55

each(arr:Arr, cb:Fun) Source: stdlib.ngs:1608

Iterates over the elements of arr, passing each in turn to cb along with args: cb(ITEM)

Parameters

cb	Function to be called with values from arr

Returns

arr

Example

s=0
[1,2,3].each(F(i) { global s; s+=i })
echo(s)  # Outputs: 6

each(arr:Arr, n:Int, cb:Fun) Source: stdlib.ngs:1669

Process each N elements of an Array at a time. Throws InvalidArgument if number of items in arr is not divisible by n. cb is called as cb(eltI, ..., eltJ) where I is multiple of n and J is I+n-1

Parameters

arr	Items to iterate in chunks of n
n	Number of items in chunk
cb	Function to be called with values from arr

Returns

arr

Example

[1,2,3,4].each(2, F(a, b) echo("$a - $b"))  # Outputs: "1 - 2" and on the next line "3 - 4"

each(h:Hash, cb:Fun) Source: stdlib.ngs:2289

Iterate a Hash.

Parameters

h	Hash to iterate
cb	Function to call with successive keys and values

Returns

h

Example

{"a": 1, "b": 2}.each(F(k, v) echo("$k=$v"))  # Outputs: "a=1" and on the next line "b=2"

each(fb:FullBox, cb:Fun) Source: stdlib.ngs:2723

Call cb with the value of the FullBox

Returns

fb

Example

Box(10).each(echo)  # Output: 10

each(eb:EmptyBox, cb:Fun) Source: stdlib.ngs:2728

Do nothing

Returns

eb

Example

Box(null).each(echo)  # No output

each(s:Success, fun:Fun) Source: stdlib.ngs:2921

Run fun with wrapped value.

each(f:Failure, fun:Fun) Source: stdlib.ngs:2937

No-op, returns f

Returns

f

each(n:Int, cb:Fun) Source: stdlib.ngs:3157

Iterate from zero up to but not including n

Parameters

cb	Function to call with current number

Returns

n

Example

10.each(echo)  # Outputs numbers from 0 to 9 inclusive, one on each line

each(s:Str, cb:Fun) Source: stdlib.ngs:3252

Iterates over all string characters (currently bytes).

Parameters

cb	Function to be called with each character from s

Returns

s

Example

"abc".each(echo)
# Output:
# a
# b
# c

each(rd:ResDef, cb:Fun) Source: autoload/Res.ngs:80

Call cb with properties of each found resource

Returns

rd

Example

AWS::Instance().each(F(i) echo(i.InstanceId))

each(i:Iter, cb:Fun) Source: autoload/Iter.ngs:98

Calls cb with each element from i

Returns

i

Example

Iter(10).each(echo)  # Prints 0 to 9

each(s:Set, cb:Fun) Source: autoload/Set.ngs:30

Call cb for each value in the set

Returns

s
