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

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

Methods

NameDescription
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
opEquals (other) Compares this to another ParameterList (and expands tuples if necessary)
opIndex (i) Returns the expanded parameter at the given index, or null if out of bounds. Complexity: O(i).
