setBoolean

replaces the existing field with a Boolean value or adds a new field.

Arguments:

• jsonObject :: pdk.net.JsonObject

• field :: pdk.core.String

• value :: pdk.core.Boolean

Result:

• No variable is returned. A field in the object was set.

Possible exceptions

• NullPointerException - throws if the input object is NULL

Example:

jsonObject :: pdk.net.JsonObject = {
    "id": 1,
    "type": "cat"
}

field :: pdk.core.String = "type"
value :: pdk.core.Boolean = true

setBoolean(jsonObject, field, value) :: Void ->
jsonObject = {
    "id": 1,
    "type": true
}

jsonObject :: pdk.net.JsonObject = {
    "id": 1,
    "type": "cat"
}

field :: pdk.core.String = "isProcessed"
value :: pdk.core.Boolean = false

setBoolean(jsonObject, field, value) :: Void ->
jsonObject = {
    "id": 1,
    "type": true,
    "isProcessed": false
}

---

setFloat

replaces the existing field with a Float value or adds a new field.

Arguments:

• jsonObject :: pdk.net.JsonObject
• field :: pdk.core.String
• value :: pdk.core.Float

Result:

• No variable is returned. A field in the object was set.

Possible exceptions

• NullPointerException - throws if the input object is NULL

Example:

jsonObject :: pdk.net.JsonObject = {
    "id": 1,
    "type": "cat"
}

field :: pdk.core.String = "price"
value :: pdk.core.Float = 10.99

setFloat(jsonObject, field, value) :: Void ->
jsonObject = {
    "id": 1,
    "type": true,
    "price": 10.99
}

---

Possible exceptions

• NullPointerException - throws if the input object is NULL

Example:

jsonObject :: pdk.net.JsonObject = {
    "id": 1,
    "type": "cat"
}

field :: pdk.core.String = "count"
value :: pdk.core.Integer = 81

setInteger(jsonObject, field, value) :: Void ->
jsonObject = {
    "id": 1,
    "type": true,
    "count": 81
}

---

setString

Example:

jsonObject :: pdk.net.JsonObject = {
    "id": 1,
    "type": "cat"
}

field :: pdk.core.String = "name"
value :: pdk.core.String = "Tom"

setString(jsonObject, field, value) :: Void ->
jsonObject = {
    "id": 1,
    "type": true,
    "name": "Tom"
}

---

setJsonObject

replaces the existing field with a JsonObject value or adds a new field.

Arguments:

• jsonObject :: pdk.net.JsonObject

    "author": {
        "name": "Peter"
    }
}

---

setJsonArray

replaces the existing field with a JsonArray value or adds a new field.

Arguments:

• jsonObject :: pdk.net.JsonObject

Possible exceptions

• NullPointerException - throws if the input object is NULL

Example:

jsonObject :: pdk.net.JsonObject = {
    "id": 1,
    "type": "book"
}

field :: pdk.core.String = "tags"
value :: pdk.net.JsonArray = [{
    "id": 1,
