Standard Abstraction

This section deals with the integration of an existing patch in another patch.

Adding a Patch From the Workspace to Another Patch

Procedure

To be used as an abstraction, a patch can be dragged from the workspace window to another patch editor .

The abstraction refers to the patch located in the workspace.

Consequently :

the abstraction and the patch in the workspace have the same name and icon
the representation of the patch remains visible in the workspace, it hasn't been moved to the patch editor
both items will be affected by subsequent operations performed in the abstraction.

No matter where the patch is open from, the displayed editor will be the same.

Preserving the Master of a Patch

Saving / Reloading a Patch

Using Duplicates

Several patch boxes with the same reference can coexist in a patch editor. Hence, the same function can be used at several steps of a program. Duplicating an abstraction creates another box referring to the same master patch. Subsequent modifications to the reference patch will therefore affect both items.

One representation of patch1 has been added inputs. The other representation has been added outputs. Both items have been equally and simultaneously modified.

Managing Abstractions in the Workspace

Renaming an Abstraction

A blue patch can only be renamed in the workspace.

Deleting a Patch

In a workspace, nothing shows that a blue patch is used as an abstraction : this must be taken into account when organizing it.

When deleting a patch from the workspace , a warning will pop up if this patch is used as an abstraction in another patch. If it is deleted its reference in the other patch editor will be replaced by a dead box .
