Detailed Description

An object on the audio graph (a Graph, Block, or Port).

Each of these is a Raul::Deletable and so can be deleted in a realtime safe way from anywhere, and they all have a map of variable for clients to store arbitrary values in (which the engine puts no significance to whatsoever).

Member Function Documentation

§ get_property()

const Atom & Ingen::Server::NodeImpl::get_property ( const Raul::URI & uri ) const

virtual

Get a single property value.

This is only useful for properties with a single value. If the requested property has several values, the first will be returned.

Reimplemented from Ingen::Resource.

References Ingen::Resource::properties().

§ parent_graph()

GraphImpl * Ingen::Server::NodeImpl::parent_graph ( ) const

virtual

The Graph this object is a child of.

Reimplemented in Ingen::Server::BlockImpl.

§ prepare_poly()

virtual bool Ingen::Server::NodeImpl::prepare_poly	(	BufferFactory &	bufs,
		uint32_t	poly
	)

pure virtual

Prepare for a new (external) polyphony value.

Preprocessor thread, poly is actually applied by apply_poly.

Returns: true on success.

Implemented in Ingen::Server::BlockImpl, Ingen::Server::PortImpl, Ingen::Server::DuplexPort, Ingen::Server::LV2Block, and Ingen::Server::Internals::NoteNode.

§ apply_poly()

virtual bool Ingen::Server::NodeImpl::apply_poly	(	RunContext &	context,
		Raul::Maid &	maid,
		uint32_t	poly
	)

pure virtual

Apply a new (external) polyphony value.

Parameters

context	Process context (process thread only).
poly	Must be <= the most recent value passed to prepare_poly.
maid	Any objects no longer needed will be pushed to this

Implemented in Ingen::Server::BlockImpl, Ingen::Server::PortImpl, Ingen::Server::DuplexPort, Ingen::Server::InputPort, Ingen::Server::LV2Block, and Ingen::Server::Internals::NoteNode.
