Public methods
close
fun close(): Unit
Close the session.
| Exceptions | |
|---|---|
java.lang.Exception |
if this resource cannot be closed |
java.lang.IllegalStateException |
if the MediaCas instance is not valid. |
android.media.MediaCasStateException |
for CAS-specific state exceptions. |
equals
fun equals(other: Any?): Boolean
Query if an object equal current Session object.
| Parameters | |
|---|---|
obj |
an object to compare to current Session object. |
| Return | |
|---|---|
Boolean |
Whether input object equal current Session object. |
getSessionId
fun getSessionId(): ByteArray
Get Session Id.
| Return | |
|---|---|
ByteArray |
session Id of the session. This value cannot be null. |
| Exceptions | |
|---|---|
java.lang.IllegalStateException |
if the MediaCas instance is not valid. |
processEcm
fun processEcm(
data: ByteArray,
offset: Int,
length: Int
): Unit
Send a received ECM packet to the specified session of the CA system.
| Parameters | |
|---|---|
data |
ByteArray: byte array of the ECM data. This value cannot be null. |
offset |
Int: position within data where the ECM data begins. |
length |
Int: length of the data (starting from offset). |
| Exceptions | |
|---|---|
java.lang.IllegalStateException |
if the MediaCas instance is not valid. |
android.media.MediaCasException |
for CAS-specific errors. |
android.media.MediaCasStateException |
for CAS-specific state exceptions. |
processEcm
fun processEcm(data: ByteArray): Unit
Send a received ECM packet to the specified session of the CA system. This is similar to Session#processEcm(byte[], int, int) except that the entire byte array is sent.
| Parameters | |
|---|---|
data |
ByteArray: byte array of the ECM data. This value cannot be null. |
| Exceptions | |
|---|---|
java.lang.IllegalStateException |
if the MediaCas instance is not valid. |
android.media.MediaCasException |
for CAS-specific errors. |
android.media.MediaCasStateException |
for CAS-specific state exceptions. |
sendSessionEvent
fun sendSessionEvent(
event: Int,
arg: Int,
data: ByteArray?
): Unit
Send a session event to a CA system. The format of the event is scheme-specific and is opaque to the framework.
| Parameters | |
|---|---|
event |
Int: an integer denoting a scheme-specific event to be sent. |
arg |
Int: a scheme-specific integer argument for the event. |
data |
ByteArray?: a byte array containing scheme-specific data for the event. This value may be null. |
| Exceptions | |
|---|---|
java.lang.IllegalStateException |
if the MediaCas instance is not valid. |
android.media.MediaCasException |

setPrivateData
fun setPrivateData(data: ByteArray): Unit
Set the private data for a session.
| Parameters | |
|---|---|
data |
ByteArray: byte array of the private data. This value cannot be null. |
| Exceptions | |
|---|---|
java.lang.IllegalStateException |
if the MediaCas instance is not valid. |
android.media.MediaCasException |
