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

DecodeHints: Undocumented

Hook: Hook is a simple pub-sub

Stats: A group of named counters

Methods

.(hl:HashLike, k:Any) Source: stdlib.ngs:1639

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:1644

Set value.

Automatically called by NGS for syntax

your_hashlike.literal_key = v

Returns

[](hl:HashLike, k:Any) Source: stdlib.ngs:1630

Get value by key. Throws KeyNotFound.

Automatically called by NGS for syntax

your_hashlike[k]

[]=(hl:HashLike, k:Any, v:Any) Source: stdlib.ngs:1634

Set value.

Automatically called by NGS for syntax

your_hashlike[k] = v

Bool(hl:HashLike) Source: stdlib.ngs:1669: Check whether hl has any elements.
Returns
Bool

del(hl:HashLike, k:Any) Source: stdlib.ngs:1688: Remove k from hl
Returns
hl

dflt(hl:HashLike, k:Any, v:Any) Source: stdlib.ngs:2035

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:1657

Iterate over keys and values.

Returns

Example

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

filter(hl:HashLike, predicate:Fun) Source: stdlib.ngs:1678

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

value of the same type as hl

Example

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

get(hl:HashLike, k:Any, dflt:Any) Source: stdlib.ngs:1648: Get value by key or dflt if it does not exist
Returns
Any

get(hl:HashLike, k:Any) Source: stdlib.ngs:1652: Get value by key or null if it does not exist
Returns
Any

Hash(hl:HashLike) Source: stdlib.ngs:1701: 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:1621: Check whether k is in the HashLike
Returns
Bool

init(hl:HashLike, h:Hash=null) Source: stdlib.ngs:1696

Create a HashLike.

Parameters

h	If provided, used as initial value.

Example

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

JsonData(hl:HashLike) Source: stdlib.ngs:1704: Convert HashLike into JSON compatible data structure - object

keys(hl:HashLike) Source: stdlib.ngs:1661: Get keys
Returns
Arr

len(hl:HashLike) Source: stdlib.ngs:1625: Get number of key-value pairs in a HashLike
Returns
Int

map_idx_key_val(hl:HashLike, mapper:Fun) Source: stdlib.ngs:1671: Undocumented

values(hl:HashLike) Source: stdlib.ngs:1665: Get values
Returns
Arr
