ModelTransformer::Input ModelTransformerFactory::getConfigurationForTransform ( Transform transform,
const std::vector< Model * > &  candidateInputModels,
Model defaultInputModel,
AudioPlaySource source = 0,
int  startFrame = 0,
int  duration = 0,
UserConfigurator configurator = 0 
)

Fill out the configuration for the given transform (may include asking the user by calling back on the UserConfigurator).

Returns the selected input model and channel if the transform is acceptable, or an input with a null model if the operation should be cancelled. Audio play source may be used to audition effects plugins, if provided.

!! This will need revision -- we'll have to have a callback

Model * ModelTransformerFactory::transform ( const Transform transform,
const ModelTransformer::Input input,
QString &  message,
AdditionalModelHandler handler = 0 
)

Return the output model resulting from applying the named transform to the given input model.

The transform may still be working in the background when the model is returned; check the output model's isReady completion status for more details. To cancel a background transform, call abandon() on its model.

If the transform is unknown or the input model is not an appropriate type for the given transform, or if some other problem occurs, return 0. Set message if there is any error or warning to report.

Some transforms may return additional models at the end of processing. (For example, a transform that splits an output into multiple one-per-bin models.) If an additionalModelHandler is provided here, its moreModelsAvailable method will be called when those models become available, and ownership of those models will be transferred to the handler. Otherwise (if the handler is null) any such models will be discarded.

The returned model is owned by the caller and must be deleted when no longer needed.

vector< Model * > ModelTransformerFactory::transformMultiple ( const Transforms transform,
const ModelTransformer::Input input,
QString &  message,
AdditionalModelHandler handler = 0 
)

Return the multiple output models resulting from applying the named transforms to the given input model.

The transforms may differ only in output identifier for the plugin: they must all use the same plugin, parameters, and programs. The plugin will be run once only, but more than one output will be harvested (as appropriate). Models will be returned in the same order as the transforms were given. The plugin may still be working in the background when the model is returned; check the output models' isReady completion statuses for more details. To cancel a background transform, call abandon() on its model.

If a transform is unknown or the transforms are insufficiently closely related or the input model is not an appropriate type for the given transform, or if some other problem occurs, return 0. Set message if there is any error or warning to report.

Some transforms may return additional models at the end of processing. (For example, a transform that splits an output into multiple one-per-bin models.) If an additionalModelHandler is provided here, its moreModelsAvailable method will be called when those models become available, and ownership of those models will be transferred to the handler. Otherwise (if the handler is null) any such models will be discarded. Note that calling abandon() on any one of the models returned by transformMultiple is sufficient to cancel all background transform activity associated with these output models.

The returned models are owned by the caller and must be deleted when no longer needed.
