Inherited constants
From class Parcelable Int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. Int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.
From class BroadcastInfoRequest Int REQUEST_OPTION_AUTO_UPDATE Request option: auto update. With this option, a response is sent only when broadcast information is detected for the first time, new values are detected. Int REQUEST_OPTION_ONESHOT Request option: one-shot With this option, only one response will be given per request. Int REQUEST_OPTION_ONEWAY Request option: one-way With this option, no response is expected after sending the request. Int REQUEST_OPTION_REPEAT Request option: repeat. With this option, a response is sent when related broadcast information is detected, even if the same information has been sent previously.

Public constructors
SignalingDataRequest(requestId: Int, option: Int, group: Int, signalingDataTypes: MutableList<String!>)

Public methods
Int	describeContents()
Int	getGroup() Gets the group with which any signaling returned will be associated.
MutableList<String!>	getSignalingDataTypes() Gets the signaling data types for which data should be retrieved.
Unit	writeToParcel(dest: Parcel, flags: Int) Flatten this object in to a Parcel.

Inherited functions

From class BroadcastInfoRequest Int getOption() Gets the request option of the request. Int getRequestId() Gets the ID of the request. The ID is used to associate the response with the request. Int getType() Gets the broadcast info type. The type indicates what broadcast information is requested, such as broadcast table, PES (packetized Elementary Stream), TS (transport stream), etc. The type of the request and the related responses should be the same.
