# RegisterFunction
## Control Functionality, Type (Regular or Container Control), and Parent Control
- **Control Functionality**: Provides a global function registration and retrieval mechanism for managing and maintaining reusable functional functions. Functions are registered by name and can be dynamically retrieved later using their names.
- **Type**: Regular control
- **Parent Control**: None (native JavaScript class)
## Initialization Parameters
- No explicit initialization parameters. The constructor `constructor()` initializes an empty object `this.rfs = {}` to store registered functions.
## Main Events
- No DOM events. This control primarily provides the following methods as its interface:
- `register(n, f)`: Registers function `f` with the name `n` into the internal storage object.
- `get(n)`: Retrieves the function registered under name `n`. Returns `null` if no such function exists (handled after catching exceptions).
