Methods

const(LilvPort) * handle() @property @nogc nothrow

World world() @property @nogc nothrow

Node node() @propertyRDF node for this port

uint index() @property @nogc nothrowPort index (may change between plugin versions).

Node symbol() @propertyShort symbol (valid C identifier).

Node name() @propertyHuman-readable name

Nodes classes() @propertyAll classes of this port

bool isA(Node portClass) @nogc nothrowDetermine if a port is of a given class (input, output, audio, etc).

Nodes properties()Return the LV2 port properties of a port. Returns: A collection of LV2 port properties or null if none

void getRange(out Node def, out Node min, out Node max)Default / min / max values. Any of the three may be null if the port has no such value. Params: def = Output default value min = Output minimum value max = Output maximum value

ScalePoints scalePoints()Get the scale points (enumeration values) of a port. This returns a collection of "interesting" named values of a port, which for example might be appropriate entries for a value selector in a UI. ...
