Class `dmd.expression.StructLiteralExp`

sd( e1, e2, e3, ... )


						
				class StructLiteralExp
				
  : Expression
				;

Fields

Name	Type	Description
`elements`	`dmd.root.array.Array!(dmd.expression.Expression)*`	parallels sd.fields[] with null entries for fields to skip
`inlinecopy`	`StructLiteralExp`	those fields need to prevent a infinite recursion when one field of struct initialized with 'this' pointer.
`isOriginal`	`bool`	used when moving instances to indicate `this is this.origin`
`origin`	`StructLiteralExp`	pointer to the origin instance of the expression. once a new expression is created, origin is set to 'this'. anytime when an expression copy is created, 'origin' pointer is set to 'origin' pointer value of the original expression.
`sd`	`StructDeclaration`	which aggregate this is for
`stageflags`	`ubyte`	anytime when recursive function is calling, 'stageflags' marks with bit flag of current stage and unmarks before return from this function. 'inlinecopy' uses similar 'stageflags' and from multiple evaluation 'doInline' (with infinite recursion) of this expression.
`stype`	`Type`	final type of result (can be different from sd's type)
`sym`	`void*`	back end symbol to initialize with literal (used as a Symbol*)
`useStaticInit`	`bool`	if this is true, use the StructDeclaration's init symbol

Methods

Name	Description
`getField` (type, offset)	Gets expression at offset of type. Returns NULL if not found.
`getFieldIndex` (type, offset)	Get index of field. Returns -1 if not found.
`accept` (v)	Visits this AST node using the given visitor.
`addressOf` ()	Take address of expression.
`checkReadModifyWrite` (rmwOp, ex)	Check whether the expression allows RMW operations, error with rmw operator diagnostic if not. ex is the RHS expression, or NULL if ++/-- is used (for diagnostics) Returns true if error occurs.
`checkType` ()	Check that the expression has a valid type. If not, generates an error "... has no type".
`checkValue` ()	Check that the expression has a valid value. If not, generates an error "... has no value".
`combine` (e1, e2)	Combine e1 and e2 by CommaExp if both are not NULL.
`copy` ()	Does not do a deep copy.
`deinitialize` ()	Deinitializes the global state of the compiler.
`deref` ()	If this is a reference, dereference it.
`extractLast` (e, e0)	If 'e' is a tree of commas, returns the rightmost expression by stripping off it from the tree. The remained part of the tree is returned via e0. Otherwise 'e' is directly returned and e0 is set to NULL.
`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.
`isIdentical` (e)	Identical, not just equal. I.e. NaNs with different bit patterns are not identical
`isLvalue` ()	Return !=0 if expression is an lvalue.
`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.
`size` ()
`toBool` ()	Statically evaluate this expression to a `bool` if possible
`toHash` ()	Compute hash function for Object.
`toString` ()
`toString` ()	Convert Object to a human readable string.
