## padCopy
Called from: src/node/db/Pad.js
## `padCopy`
Things in context:
Called from: `src/node/db/Pad.js`
1. originalPad - the source pad instance
2. destinationID - the id of the pad copied from originalPad
Called when a pad is copied so that plugins can copy plugin-specific database
records or perform some other plugin-specific initialization.
This hook gets called when an existing pad was copied.
Order of events when a pad is copied:
1. Destination pad is deleted if it exists and overwrite is permitted. This
causes the `padRemove` hook to run.
2. Pad-specific database records are copied in the database, except for
records with plugin-specific database keys.
3. A new Pad object is created for the destination pad. This causes the
`padLoad` hook to run.
4. This hook runs.
Context properties:
* `originalPad`: The source Pad object.
* `destinationID`: The ID of the pad copied from `originalPad`.
