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 and overloads for `opEquals` should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for `null` on the typed overload.
`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'.
