This function takes a data.table containing user-supplied function
definitions and parses them into a structured format. The input data.table
is expected to have specific columns that include the function type, the
function itself, the name of the function, and a unique hash for the
function. The output is a list of data.table objects, where each
data.table corresponds to a unique function type and contains detailed
information about each function, including a character representation and the
callable function itself.
Usage
mk_userdef_fn_dt(x, env = parent.frame())Arguments
- x
A
data.tableobject representing the endpoint definition data model, which should contain the following columns:fn_type: Character vector specifying the type of function.
fn: List of callables (length 1) representing the function to be called.
fn_name: Character vector with the name of the function.
fn_hash: Character vector with a unique hash for each function.
- env
The environment from which to evaluate the functions. The default is the parent frame from which the function is called.
Value
A data.table with each row containing a parsed function definition. The columns include:
fn_type: Character vector with the type of function.
fn_hash: Character vector with the unique hash of the function.
fn_name: Character vector with the name of the function.
fn_call_char: Character vector with the function call as a string.
fn_callable: List of callables representing the parsed function.
