Class `dmd.mtype.Parameter`


						
				class Parameter
				
  : ASTNode
				;

Methods

Name	Description
`_foreach` (parameters, dg)	Expands tuples in args in depth first order. Calls dg(void ctx, size_t argidx, Parameter arg) for each Parameter. If dg returns !=0, stops and returns that value else returns 0. Use this function to avoid the O(N + N^2/2) complexity of calculating dim and calling N times getNth.
`dim` (parameters)	Determine number of arguments, folding in tuples.
`getNth` (parameters, nth)	Get nth `Parameter`, folding in tuples.
`isCovariant` (returnByRef, p, previewIn)	Compute covariance of parameters `this` and `p` as determined by the storage classes of both.
`isLazyArray` ()	Determine if parameter is a lazy array of delegates. If so, return the return type of those delegates. If not, return NULL.
`isReference` ()
`accept` (v)	Visits this AST node using the given visitor.
`factory` (classname)	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`opCmp` (o)	Compare with another Object obj.
`opEquals` (o)	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides for `opEquals` should attempt to compare objects by their contents.
`toHash` ()	Compute hash function for Object.
`toString` ()
`toString` ()	Convert Object to a human readable string.

Aliases

Name	Description
`ForeachDg`	Type of delegate when iterating solely on the parameters
`SemanticForeachDg`	Type of delegate when iterating on both the original set of parameters, and the type tuple. Useful for semantic analysis. 'o' stands for 'original' and 'e' stands for 'expanded'.
