addBoolean

adds new element with type Boolean to the input array.

Arguments:

• jsonArray :: pdk.net.JsonArray

• value :: pdk.core.Boolean

Result:

• No variable is returned. An array contains a new element.

Possible exceptions

• NullPointerException - throws if the input jsonArray is NULL

Example:

jsonArray :: pdk.net.JsonArray = []
value :: pdk.core.Boolean = true

addBoolean(jsonArray, value) :: Void ->
jsonArray = [true]
value = true

---

addFloat

adds new element with type Float to the input array.

Arguments:

• jsonArray :: pdk.net.JsonArray

• value :: pdk.core.Float

Result:

• No variable is returned. An array contains a new element.

Possible exceptions

• NullPointerException - throws if the input jsonArray is NULL

Example:

jsonArray :: pdk.net.JsonArray = []
value :: pdk.core.Float = 3.1415

addFloat(jsonArray, value) :: Void ->
jsonArray = [3.1415]
value = 3.1415

---

addInteger

adds new element with type Integer to the input array.

Arguments:

• jsonArray :: pdk.net.JsonArray

• value :: pdk.core.Integer

Result:

• No variable is returned. An array contains a new element.

Possible exceptions

• NullPointerException - throws if the input jsonArray is NULL

Example:

jsonArray :: pdk.net.JsonArray = []
value :: pdk.core.Integer = 100

addString

adds new element with type String to the input array.

Arguments:

• jsonArray :: pdk.net.JsonArray

• value :: pdk.core.String

Result:

• No variable is returned. An array contains a new element.

Possible exceptions
