Struct `dmd.mtype.ParameterList`

Represents a function's formal parameters + variadics info. Length, indexing and iteration are based on a depth-first tuple expansion.


						
				struct ParameterList
				;

Fields

Name	Type	Description
`parameters`	`dmd.root.array.Array!(dmd.mtype.Parameter)*`	The raw (unexpanded) formal parameters, possibly containing tuples.

Methods

Name	Description
`length` ()	Returns the number of expanded parameters. Complexity: O(N).
`opApply` (dg)	Iterates over the expanded parameters. Complexity: O(N). Prefer this to avoid the O(N + N^2/2) complexity of calculating length and calling N times opIndex.
`opApply` (dg)	Iterates over the expanded parameters, matching them with the unexpanded ones, for semantic processing
`opIndex` (i)	Returns the expanded parameter at the given index, or null if out of bounds. Complexity: O(i).
