Class `dmd.cond.StaticForeach`

Implements common functionality for StaticForeachDeclaration and StaticForeachStatement This performs the necessary lowerings before dmd.statementsem.makeTupleForeach can be used to expand the corresponding static foreach declaration or statement.


						
				class StaticForeach
  : RootObject;

Fields

Name	Type	Description
`aggrfe`	`ForeachStatement`	Not `null` iff the `static foreach` is over an aggregate. In this case, it contains the corresponding ForeachStatement. For StaticForeachDeclaration, the body is `null`.
`needExpansion`	`bool`	true if it is necessary to expand a tuple into multiple variables (see lowerNonArrayAggregate).
`rangefe`	`ForeachRangeStatement`	Not `null` iff the `static foreach` is over a range. Exactly one of the `aggrefe` and `rangefe` fields is not null. See `aggrfe` field for more details.

Methods

Name	Description
`createForeach` (loc, parameters, s)	Create a `foreach` statement from `aggrefe/rangefe` with given `foreach` variables and body `s`.
`createTuple` (loc, type, e)	Create the AST for an instantiation of a suitable tuple type.
`createTupleType` (loc, e, sc)	For a `static foreach` with multiple loop variables, the aggregate is lowered to an array of tuples. As D does not have built-in tuples, we need a suitable tuple type. This generates a `struct` that serves as the tuple type. This type is only used during CTFE and hence its typeinfo will not go to the object file.
`ready` ()
`wrapAndCall` (loc, s)	Wrap a statement into a function literal and call it.
`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.
