ParameterList

Represents a function's formal parameters + variadics info. Length, indexing and iteration are based on a depth-first tuple expansion. https://dlang.org/spec/function.html#ParameterList

extern (C++)

struct ParameterList {

Constructors

this this(Parameters* parameters, VarArg varargs, StorageClass stc): Undocumented in source.

length size_t length(): Returns the number of expanded parameters. Complexity: O(N).
opApply int opApply(Parameter.ForeachDg 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 int opApply(Parameter.SemanticForeachDg dg): Iterates over the expanded parameters, matching them with the unexpanded ones, for semantic processing
opIndex Parameter opIndex(size_t i): Returns the expanded parameter at the given index, or null if out of bounds. Complexity: O(i).
syntaxCopy ParameterList syntaxCopy(): Undocumented in source. Be warned that the author may not have intended to support it.

parameters Parameters* parameters;: The raw (unexpanded) formal parameters, possibly containing tuples.
stc StorageClass stc;: Undocumented in source.
varargs VarArg varargs;: Undocumented in source.
