HashLike type

Base type for user-defined hash-like types. This is a workaround: it's not possible currently no inherit from the built-in Hash type.

Direct parent types

Eachable2: Eachable which each() calls the callback with two arguments
Direct subtypes: 2

Direct children types

Hook: Hook is a simple pub-sub

Stats: A group of named counters

Methods

.(hl:HashLike, k:Any) Source: stdlib.ngs:702

Get value by key. Throws KeyNotFound.

Automatically called by NGS for syntax

your_hashlike.literal_key

Returns

Any

.=(hl:HashLike, k:Any, v:Any) Source: stdlib.ngs:707

Set value.

Automatically called by NGS for syntax

your_hashlike.literal_key = v

Returns

[](hl:HashLike, k:Any) Source: stdlib.ngs:693

Get value by key. Throws KeyNotFound.

Automatically called by NGS for syntax

your_hashlike[k]

[]=(hl:HashLike, k:Any, v:Any) Source: stdlib.ngs:697

Set value.

Automatically called by NGS for syntax

your_hashlike[k] = v

Bool(hl:HashLike) Source: stdlib.ngs:735: Check whether hl has any elements.
Returns
Bool

dflt(hl:HashLike, k:Any, v:Any) Source: stdlib.ngs:984

Set a key if it's not already set

Returns

Key value, the already-existed or new.

Example

mysomething.dflt(k, []).push(elt)

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

Iterate over keys and values.

Returns

Example

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

filter(hl:HashLike, predicate:Fun) Source: stdlib.ngs:744

Filter hash. Build new HashLike with kev-value pairs selected by predicate.

Parameters

predicate

Test function to be called with one key and one value at a time.

Returns

HashLike

Example

my_hashlike.filter(F(k, v) k == 'a')

get(hl:HashLike, k:Any, dflt:Any) Source: stdlib.ngs:711: Get value by key or dflt if it does not exist
Returns
Any

get(hl:HashLike, k:Any) Source: stdlib.ngs:715: Get value by key or null if it does not exist
Returns
Any

Hash(hl:HashLike) Source: stdlib.ngs:762: Get the underlying Hash with all the keys/values of the HashLike. Note: the returned value is not a copy.
Returns
Hash

in(k:Any, hl:HashLike) Source: stdlib.ngs:684: Check whether k is in the HashLike
Returns
Bool

init(hl:HashLike, h:Hash=null) Source: stdlib.ngs:753

Create a HashLike.

Parameters

h	If provided, used as initial value.

Example

HashLike(%{a aha b bee}) # <HashLike a=aha b=bee>

keys(hl:HashLike) Source: stdlib.ngs:727: Get keys
Returns
Arr

len(hl:HashLike) Source: stdlib.ngs:688: Get number of key-value pairs in a HashLike
Returns
Int

map_idx_key_val(hl:HashLike, mapper:Fun) Source: stdlib.ngs:737: Undocumented

values(hl:HashLike) Source: stdlib.ngs:731: Get values
Returns
Arr
