Builder

protected Builder()

Default constructor for a Builder object.

Method Details

build

public Element build()

Finish building the Element object. This will call GObject.withProperties(org.gnome.glib.Type, java.lang.String[], org.gnome.gobject.Value[]) to create a new GObject instance, which is then cast to Element.

Overrides:

build in class GstObject.Builder<B extends Element.Builder<B>>

Returns:

a new instance of Element with the properties that were set in the Builder object.

onNoMorePads

public B onNoMorePads(Element.NoMorePadsCallback handler)

This signals that the element will not generate more dynamic pads. Note that this signal will usually be emitted from the context of the streaming thread.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• Element.NoMorePadsCallback.run()

onPadAdded

public B onPadAdded(Element.PadAddedCallback handler)

a new GstPad has been added to the element. Note that this signal will usually be emitted from the context of the streaming thread. Also keep in mind that if you add new elements to the pipeline in the signal handler you will need to set them to the desired target state with gst_element_set_state() or gst_element_sync_state_with_parent().

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• Element.PadAddedCallback.run(org.freedesktop.gstreamer.gst.Pad)

onPadRemoved

public B onPadRemoved(Element.PadRemovedCallback handler)

a GstPad has been removed from the element

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• Element.PadRemovedCallback.run(org.freedesktop.gstreamer.gst.Pad)
