Introduction
Package Name
phantasy is brief for Physics High-level Applications and Toolkit for Accelerator System.Architecture
Lattice
Element
Element with
Channel Access
support is instantiated from CaElement, which in
aggregate attaches relevant information with the target device.
From the user side, interested information of the element can be reached by referring the attributes, which are composed of static and dynamic fields, the static fields are to represent the device properties that do not change often, especially the attribute name itself in Python object, e.g. device name, type, geometry length and location, etc., while the dynamic fields are to represent the device properties regarding to Channel Access ability, that is:
The attribute name is not fixed, depends on the device configuration;
The value of the attribute usually is not fixed, depends on the runtime;
Each dynamic field is instantiated from
CaField.
