Detailed Description

cannam@0: A base class for plugins with optional configurable parameters, programs, etc. cannam@0:

cannam@21: The Vamp::Plugin is derived from this, and individual Vamp plugins should derive from that.

cannam@21: This class does not provide the necessary interfaces to instantiate or run a plugin. It only specifies an interface for retrieving those controls that the host may wish to show to the user for editing. It could meaningfully be subclassed by real-time plugins or other sorts of plugin as well as Vamp plugins. cannam@21:

virtual std::string Vamp::PluginBase::getIdentifier ( ) const [pure virtual]

cannam@0:

cannam@0: cannam@0:

cannam@0: Get the computer-usable name of the plugin. cannam@0:

cannam@0: This should be reasonably short and contain no whitespace or punctuation characters. It may only contain the characters [a-zA-Z0-9_-]. This is the authoritative way for a program to identify a plugin within a given library.

cannam@0: This text may be visible to the user, but it should not be the main text used to identify a plugin to the user (that will be the name, below).

cannam@0: Example: "zero_crossings" cannam@21:

Implemented in Vamp::PluginHostAdapter, Vamp::HostExt::PluginWrapper, AmplitudeFollower, FixedTempoEstimator, PercussionOnsetDetector, PowerSpectrum, SpectralCentroid, and ZeroCrossing.

cannam@0:

cannam@0: cannam@0:

cannam@0: Get a human-readable name or title of the plugin. cannam@0:

cannam@0: This should be brief and self-contained, as it may be used to identify the plugin to the user in isolation (i.e. without also showing the plugin's "identifier").

cannam@0: Example: "Zero Crossings" cannam@21:

Implemented in Vamp::PluginHostAdapter, Vamp::HostExt::PluginWrapper, AmplitudeFollower, FixedTempoEstimator, PercussionOnsetDetector, PowerSpectrum, SpectralCentroid, and ZeroCrossing.

cannam@0:

cannam@0: cannam@0:

cannam@0: Get a human-readable description for the plugin, typically a line of text that may optionally be displayed in addition to the plugin's "name". cannam@0:

cannam@0: May be empty if the name has said it all already.

cannam@0: Example: "Detect and count zero crossing points" cannam@21:

cannam@0: This should be a short identifying text, as it may be used to label plugins from the same source in a menu or similar. cannam@21:

Implemented in Vamp::PluginHostAdapter, Vamp::HostExt::PluginWrapper, AmplitudeFollower, FixedTempoEstimator, PercussionOnsetDetector, PowerSpectrum, SpectralCentroid, and ZeroCrossing.

cannam@0:

cannam@0: cannam@0:

cannam@0: Get the program settings available in this plugin. cannam@0:

cannam@0: A program is a named shorthand for a set of parameter values; changing the program may cause the plugin to alter the values of its published parameters (and/or non-public internal processing parameters). The host should re-read the plugin's parameter values after setting a new program.

cannam@0: The programs must have unique names. cannam@21:
