Method Detail

setOrAppendToArray

public static void setOrAppendToArray(com.google.gson.JsonObject object,
                                      String propertyName,
                                      com.google.gson.JsonElement newValue)

Sets the given newValue as the value of property propertyName on parent, wrapping it in an array if necessary.

The behavior is as follows:

• If there is currently no value for this property, the property is simply set to newValue using JsonObject.add(String, JsonElement).
• If the current value of the property is an array, newValue is added to this array.
• Otherwise, the current value is replaced by an array containing the current value followed by the newValue.

Parameters:

object - The object whose property must be set.

propertyName - The name of the property to set.

newValue - The value to set.
