Class `dmd.statement.ForwardingStatement`

Statement whose symbol table contains foreach index variables in a local scope and forwards other members to the parent scope. This wraps a statement.



class ForwardingStatement

  : Statement
;

Also see: ForwardingAttribDeclaration

Fields

Name	Type	Description
`statement`	`Statement`	The wrapped statement.
`sym`	`ForwardingScopeDsymbol`	The symbol containing the `static foreach` variables.

Methods

Name	Description
`flatten`	ForwardingStatements are distributed over the flattened sequence of statements. This prevents flattening to be "blocked" by a ForwardingStatement and is necessary, for example, to support generating scope guards with `static foreach`:
`accept`	Support Visitor Pattern
`arraySyntaxCopy`	Do syntax copy of an array of Statement's.
`comeFrom`
`factory`	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`hasBreak`	Determine if an enclosed `break` would apply to this statement, such as if it is a loop or switch statement.
`hasCode`
`hasContinue`	Determine if an enclosed `continue` would apply to this statement, such as if it is a loop statement.
`isBreakStatement`	A cheaper method of doing downcasting of Statements.
`isCaseStatement`	A cheaper method of doing downcasting of Statements.
`isCompoundStatement`	A cheaper method of doing downcasting of Statements.
`isDefaultStatement`	A cheaper method of doing downcasting of Statements.
`isDtorExpStatement`	A cheaper method of doing downcasting of Statements.
`isErrorStatement`	A cheaper method of doing downcasting of Statements.
`isExpStatement`	A cheaper method of doing downcasting of Statements.
`isForwardingStatement`	A cheaper method of doing downcasting of Statements.
`isGotoCaseStatement`	A cheaper method of doing downcasting of Statements.
`isGotoDefaultStatement`	A cheaper method of doing downcasting of Statements.
`isIfStatement`	A cheaper method of doing downcasting of Statements.
`isLabelStatement`	A cheaper method of doing downcasting of Statements.
`isReturnStatement`	A cheaper method of doing downcasting of Statements.
`isScopeStatement`	A cheaper method of doing downcasting of Statements.
`last`	Find last statement in a sequence of statements.
`opCmp`	Compare with another Object obj.
`opEquals`	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.
`scopeCode`	If this statement has code that needs to run in a finally clause at the end of the current scope, return that code in the form of a Statement.
`toHash`	Compute hash function for Object.
`toString`
`toString`	Convert Object to a human readable string.
`usesEH`
