= class Gst::Bin
Base container element.
== Object Hierarchy
- * Gst::Object
- * Gst::Element
+ * ((<Gst::Object>))
+ * ((<Gst::Element>))
== Class Methods
--- Gst::Bin.new(aStringName=nil)
Constructs a new Gst::Bin object.
If element name is ommited (or nil), then the bin will receive a guaranteed
unique name, consisting of the "bin" string and a number.
If name is given, it will be given the name supplied.
== Instance Methods
--- add(*elements)
Adds one or more Gst::Element objects to the bin.
Returns an array of all Gst::Element objects in the container.
--- clear
Synonym for Gst::Bin#remove_all.
--- clock
Gets the current clock of the (scheduler of the) bin.
This method overrides Gst::Element#get_clock.
--- each_element { |aGstElement| block }
Calls the block for each element in the bin, passing a reference to
the Gst::Element as parameter.
Always returns nil.
--- elements
Returns an array of all Gst::Element objects in the container.
--- get_by_name(aName)
Gets the element with the given name from the bin, as a reference to
a Gst::Element object. Returns nil if the bin does not contain an element
with the given name.
--- has_fixed_clock?
Checks if the Gst::Bin::FLAG_FIXED_CLOCK flag is set on the object.
--- iterate
Iterates over the elements in this bin.
Returns true if the bin did something useful. This value can be used
to determine if the bin is in EOS ("end of stream").
--- length
Returns the number of elements in the container.
--- manager?
Checks if the Gst::Bin::FLAG_MANAGER flag is set on the object.
--- prefers_cothreads?
Checks if the Gst::Bin::FLAG_PREFER_COTHREADS flag is set on the object.
--- remove(*elements)
Removes one or more Gst::Element objects from the bin, unparenting
as well.
Returns an array of all Gst::Element objects in the container.
--- remove_all
Removes all Gst::Element objects in the bin.
Returns an empty array.
--- schedulable?
Checks if the Gst::Bin::FLAG_SCHEDULABLE flag is set on the object.
--- size
Synonym for Gst::Bin#length.
== Constants
--- FLAG_FIXED_CLOCK
This bin has a fixed clock.
--- FLAG_MANAGER
This bin is a manager of child elements, i.e. a Gst::Pipeline or
a Gst::Thread.
--- FLAG_PREFER_COTHREADS
This bin prefers to have cothreads when its an option, over chain-based.
--- FLAG_SCHEDULABLE
This bin iterates itself.
== Signals
--- element-added
--- element-removed
