dw::core::Objects

Returns a list of key value pair object describing the object entries

Example

%dw 2.0
import dw::core::Objects
---
Objects::entrySet({a: true, b: 1})

Output

[{key: "a", value: true}, {key: "b", value: 1}]

Functions

EntryAt

entryAt({ (K): V }, Number): { (K)?: V } | Null

Returns selecting only the entry at the specified index. If the index is not valid it return null. If index es less than 0 then it will start from the last element e.g {a: true, b: 1} entryAt -1 returns the last entry

Example

%dw 2.0
import dw::core::Objects
---
Objects::entryAt({a: true, b: 1}, 0)

Output

{a: true}

EntrySet

entrySet(T)

KeySet

keySet(T): ?

Returns the list of key names of an object

Example

%dw 2.0
import dw::core::Objects
---
Objects::nameSet({a: true, b: 1})

Output

["a","b"]

MergeWith

mergeWith(T, V): ?

Overrides the source with the target object so that the result with contain all the properties from the target plus the properties on the source that are not declared on the target

Example

%dw 2.0
import mergeWith from dw::core::Objects
---
{a: true, b: 1} mergeWith {a: false, c: "Test"}

Output

{a: false, b: 1 , c: "Test"}

mergeWith(Null, T): T

Helper method to make mergetWith null friendly

mergeWith(T, Null): T

Helper method to make mergetWith null friendly

NameSet

nameSet(Object): Array<String>

Returns the list of key names of an object

Example

%dw 2.0
import dw::core::Objects
---
Objects::nameSet({a: true, b: 1})

Output

["a","b"]

ValueSet

valueSet({ K?: V }): Array<V>

Returns the list of key values of an object

Example

%dw 2.0
import dw::core::Objects
---
Objects::nameSet({a: true, b: 1})

Output

[true,1]
