Adds a value to an array.
Example 
Dim o As New JSONMBS

o.Add 1

MessageBox o.toString

Variant is converted to JSONMBS if needed.

If the self is an empty object, we replace it with an empty array and add the value.

Same as Add method.

JSONMBS.AddAt(index As Integer, value As Variant)   New in 23.5

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 23.5 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Insert a value to an array at the given index.
Example 
Dim o As New JSONMBS

o.Append 1
o.AddAt 1,2

MessageBox o.toString

o.AddAt 1,3

MessageBox o.toString

Variant is converted to JSONMBS if needed.

If the self is an empty object, we replace it with an empty array and insert the value.

Same as Insert method.

JSONMBS.AddItemToArray(item as JSONMBS)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 13.3 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Adds an item to an array.
Example 

Var subscriptionId As Integer = 123456
Var Quantity As Integer = 1

// build inner object
Dim ji As JSONMBS = JSONMBS.NewObjectNode

ji.AddItemToObject "subscriptionId", JSONMBS.NewNumberNode(subscriptionId)
ji.AddItemToObject "newQuantity", JSONMBS.NewNumberNode(Quantity)

// array around it
Dim ja As JSONMBS = JSONMBS.NewArrayNode
ja.AddItemToArray ji

// and object around
Dim jo As JSONMBS = JSONMBS.NewObjectNode
jo.AddItemToObject "subscriptionAmendmentParameters", ja


Dim json As String = jo.toString
MessageBox json

'{
'	"subscriptionAmendmentParameters":    [
'		{
'			"subscriptionId":    123456,
'			"newQuantity":    1
'		}
'	]
'}

If you add item from new nodes created with plugin, we add them to the tree.
If you add items from existing node from other JSON tree, we add references.

Some examples using this method:

JSONMBS.AddItemToObject(label as string, value as JSONMBS)

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 13.3 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Adds an item to an object with given label.
Example 

Var subscriptionId As Integer = 123456
Var Quantity As Integer = 1

// build inner object
Dim ji As JSONMBS = JSONMBS.NewObjectNode

ji.AddItemToObject "subscriptionId", JSONMBS.NewNumberNode(subscriptionId)
ji.AddItemToObject "newQuantity", JSONMBS.NewNumberNode(Quantity)

// array around it
Dim ja As JSONMBS = JSONMBS.NewArrayNode
ja.AddItemToArray ji

// and object around
Dim jo As JSONMBS = JSONMBS.NewObjectNode
jo.AddItemToObject "subscriptionAmendmentParameters", ja


Dim json As String = jo.toString
MessageBox json

'{
'	"subscriptionAmendmentParameters":    [
'		{
'			"subscriptionId":    123456,
'			"newQuantity":    1
'		}
'	]
'}

If you add item from new nodes created with plugin, we add them to the tree.
If you add items from existing node from other JSON tree, we add references.

Some examples using this method:

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 20.4 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All

JSONMBS.Convert as Variant

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 19.2 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All

// convert to Dictionary
Dim v As Variant = j.Convert

// and back
Dim o As JSONMBS = JSONMBS.Convert(v)

// show
MsgBox o.toString

Depending on the JSON content, you get variants containing values (string, double, boolean or nil), dictionaries or array of variants.

Dictionary is not case sensitive, so may not work correctly if you have duplicate keys with only different in case.

Break

Convenience function to get all entries.
Converts values to variants as needed.

Works for both objects and arrays.

JSONMBS.Equals(Other as JSONMBS) as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 19.0 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Checks if two JSON are equal.
Example

dim j3 as JSONMBS = JSONMBS.NewNumberNode(6)

if not j1.Equals(j2) then
  break // failed
end if

if j3.Equals(j2) then
  break // failed
end if

Break // okay

We compare recursively all nodes.
If structure and values are the same, we return true, otherwise false.
Objects do not need to have same order for entries.

JSONMBS.FilterObjectArray(Name as String, Other as JSONMBS) as JSONMBS   New in 23.5

j1.AddItemToObject "name", JSONMBS.NewStringNode("John")
j.AddItemToArray j1

Dim j2 As JSONMBS = JSONMBS.NewObjectNode
j2.AddItemToObject "id", JSONMBS.NewNumberNode(123)
j2.AddItemToObject "name", JSONMBS.NewStringNode("Matt")
j.AddItemToArray j2

Dim j3 As JSONMBS = JSONMBS.NewObjectNode
j3.AddItemToObject "id", JSONMBS.NewNumberNode(124)
j3.AddItemToObject "name", JSONMBS.NewStringNode("Bob")
j.AddItemToArray j3

Dim resultArray As JSONMBS = j.FilterObjectArray("id", JSONMBS.NewNumberNode(123))
Dim firstEntry As JSONMBS = resultArray.ArrayItem(0)

Break

Similar as if you loop and look for index of matching items with FindValueInObjectArray and transfer it yourself to a new array.

JSONMBS.FindValueInArray(Other as JSONMBS, StartIndex as Integer = 0) as Integer   New in 23.5

Type Topic Plugin Version macOS Windows Linux iOS Targets
method JavaScript Object Notation MBS Util Plugin 23.5 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Queries index of value in array.
Example 
dim j1 as JSONMBS = JSONMBS.NewIntegerArray(array(3,4,5,6,7))
dim j2 as JSONMBS = JSONMBS.NewNumberNode(5)
dim j3 as JSONMBS = JSONMBS.NewNumberNode(8)
dim j4 as JSONMBS = JSONMBS.NewStringNode("5")

dim index1 as integer = j1.FindValueInArray(j2) // we can find this
dim index2 as integer = j1.FindValueInArray(j3) // value not found
dim index3 as integer = j1.FindValueInArray(j4) // can't find string in number array

if index1 = 2 and index2 = -1 and index3 = -1 then
  Break // okay
else
  Break // failed
end if

Returns zero based index or -1 if not found.

Version 20.0 or newer allows with ByContent parameter = true to find by content, so number can be found via text.

StartIndex parameter added in version 21.5: Index of first element to check. Zero if not specified.
If you like to continue searching, you can pass last result + 1.
