| * This annotator will copy the text of one view to another view. It is required that source view |
| * already exists. If the destination view does not yet exist, then it will be created. A use case |
| * for this analysis engine is when you have a "gold view" which is populated with text and |
| * gold-standard annotations. Now you want to run your system/pipeline on a "system view" so that at |
| * the end you can compare the annotations in the system view with those in the gold view. It is |
| * convenient to have an annotator that simply copies the text from the gold view to the system view |
| * before running a pipeline on the system view. |
