EventType (GStreamer 1.x Java Core 1.4.0 API)

java.lang.Object
- java.lang.Enum<EventType>
- - org.freedesktop.gstreamer.event.EventType

All Implemented Interfaces:

Serializable, Comparable<EventType>, NativeEnum<EventType>
```
public enum EventType
extends Enum<EventType>
implements NativeEnum<EventType>
```
The standard event types that can be sent in a pipeline.
See upstream documentation at https://gstreamer.freedesktop.org/data/doc/gstreamer/stable/gstreamer/html/GstEvent.html#GstEventType
The custom event types can be used for private messages between elements that can't be expressed using normal GStreamer buffer passing semantics.
Custom events carry an arbitrary Structure. Specific custom events are distinguished by the name of the structure.

- Enum Constant Detail
  - UNKNOWN
```
public static final EventType UNKNOWN
```
    Unknown event
  - FLUSH_START
```
public static final EventType FLUSH_START
```
    Start a flush operation. This event clears all data from the pipeline and unblock all streaming threads.
  - FLUSH_STOP
```
public static final EventType FLUSH_STOP
```
    Stop a flush operation. This event resets the running-time of the pipeline.
  - STREAM_START
```
public static final EventType STREAM_START
```
    Event to mark the start of a new stream. Sent before any other serialized event and only sent at the start of a new stream, not after flushing seeks.
  - CAPS
```
public static final EventType CAPS
```
    #GstCaps event. Notify the pad of a new media type.
  - SEGMENT
```
public static final EventType SEGMENT
```
    A new media segment follows in the dataflow. The segment events contains information for clipping buffers and converting buffer timestamps to running-time and stream-time.
  - STREAM_COLLECTION
```
@Gst.Since(minor=10)
public static final EventType STREAM_COLLECTION
```
    A new #GstStreamCollection is available (Since 1.10)
  - TAG
```
public static final EventType TAG
```
    A new set of metadata tags has been found in the stream.
  - BUFFERSIZE
```
public static final EventType BUFFERSIZE
```
    Notification of buffering requirements. Currently not used yet.
  - SINK_MESSAGE
```
public static final EventType SINK_MESSAGE
```
    An event that sinks turn into a message. Used to send messages that should be emitted in sync with rendering.
  - STREAM_GROUP_DONE
```
@Gst.Since(minor=10)
public static final EventType STREAM_GROUP_DONE
```
    Indicates that there is no more data for the stream group ID in the message. Sent before EOS in some instances and should be handled mostly the same. (Since 1.10)
  - EOS
```
public static final EventType EOS
```
    End-Of-Stream. No more data is to be expected to follow without a SEGMENT event.
  - TOC
```
public static final EventType TOC
```
    An event which indicates that a new table of contents (TOC) was found or updated.
  - PROTECTION
```
public static final EventType PROTECTION
```
    An event which indicates that new or updated encryption information has been found in the stream.
  - SEGMENT_DONE
```
public static final EventType SEGMENT_DONE
```
    Marks the end of a segment playback.
  - GAP
```
public static final EventType GAP
```
    Marks a gap in the datastream.
  - QOS
```
public static final EventType QOS
```
    A quality message. Used to indicate to upstream elements that the downstream elements should adjust their processing rate.
  - SEEK
```
public static final EventType SEEK
```
    A request for a new playback position and rate.
  - NAVIGATION
```
public static final EventType NAVIGATION
```
    Navigation events are usually used for communicating user requests, such as mouse or keyboard movements, to upstream elements.
  - LATENCY
```
public static final EventType LATENCY
```
    Notification of new latency adjustment. Sinks will use the latency information to adjust their synchronisation.

  - RECONFIGURE
```
public static final EventType RECONFIGURE
```
    A request for upstream renegotiating caps and reconfiguring.
  - TOC_SELECT
```
public static final EventType TOC_SELECT
```
    A request for a new playback position based on TOC entry's UID.
  - SELECT_STREAMS
```
@Gst.Since(minor=10)
public static final EventType SELECT_STREAMS
```
    A request to select one or more streams (Since 1.10)

```
    Custom out-of-band downstream event.
  - CUSTOM_DOWNSTREAM_STICKY
```
public static final EventType CUSTOM_DOWNSTREAM_STICKY
```
    Custom sticky downstream event.

```
    Custom upstream or downstream out-of-band event.
- Method Detail
  - values
```
public static EventType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (EventType c : EventType.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static EventType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - intValue
```
public int intValue()
```
    Specified by:
    
    intValue in interface NativeEnum<EventType>
