createObject

public static java.lang.Object createObject(java.lang.String rawJSON)
                                     throws TwitterException

Construct an object from rawJSON string. This method may be called when you do not know what a given raw JSON string contains. It will do the work of determining what type of object the JSON represents, and constructing the respective object type. For example, if the JSON contents represents a Status, then a Status will be returned. If it represents a deletion notice, then a StatusDeletionNotice will be returned. The caller can simply use instanceof to handle the returned object as applicable. NOTE: the raw JSONObject will be returned in cases where there isn't a discrete respective object type that can be constructed. That way, the caller can at least have access to the JSON itself.

Parameters:

rawJSON - raw JSON form as String

Returns:

the respective constructed object, or the JSONObject in the case where we cannot determine the object type.

Throws:

TwitterException - when provided string is not a valid JSON string.

Twitter4J 2.1.9
