Plugin.supportedFeatures
Nodes supportedFeatures()Get the LV2 Features supported (required or optionally) by a plugin.
A feature is “supported” by a plugin if it is required OR optional.
Since required features have special rules the host must obey, this function probably shouldn’t be used by normal hosts. Using getOptionalFeatures() and getRequiredFeatures() separately is best in most cases.
Returns
Collection of supported features or null
