ptable Package
devsup.ptable
The devsup.ptable
module provides the means to define a Parameter Table, which is
something like a dictionary (parameter name <-> dict key) where a
parameter may be associated (attached) with zero or more EPICS
records.
Changes to a parameter may be reflected in the attached records. A change in an attached record will update the parameter value, and optionally, involve some functions (actions) to make some use of the new value.
The basis of all tables is the TableBase class. User code will typically
sub-class TableBase.
