Chris@0 | 26 * A Transform turns one data model into another. |
Chris@0 | 27 * |
Chris@0 | 28 * Typically in this application, a Transform might have a |
Chris@0 | 29 * DenseTimeValueModel as its input (e.g. an audio waveform) and a |
Chris@0 | 30 * SparseOneDimensionalModel (e.g. detected beats) as its output. |
Chris@0 | 31 * |
Chris@0 | 32 * The Transform typically runs in the background, as a separate |
Chris@0 | 33 * thread populating the output model. The model is available to the |
Chris@0 | 34 * user of the Transform immediately, but may be initially empty until |
Chris@0 | 35 * the background thread has populated it. |
