* \class Branch
|
|
*
|
|
* A class describing a 'branch', i.e., a named alternative for
|
|
* selectively outputting some parts of a document while suppressing
|
|
* other parts.
|
|
*
|
|
* A branch has a name, can either be selected or not, and uses a
|
|
* user-specifyable background colour. All these can be set and
|
|
* queried.
|
|
*
|
|
* \class BranchList
|
|
*
|
|
* A class containing a vector of all defined branches within a
|
|
* document. Has methods for selecting or deselecting branches by
|
|
* name, for outputting a '|'-separated string of all elements or only
|
|
* the selected ones, and for adding and removing elements.
