Statement
: dmd.ast_node.ASTNode; Specification http://dlang.org/spec/statement.html
- static Statements*
arraySyntaxCopy
(Statements*a
); - Do syntax copy of an array of Statement's.
- const pure nothrow bool
hasBreak
(); - Determine if an enclosed break would apply to this statement, such as if it is a loop or switch statement.Returns:true if it does
- const pure nothrow bool
hasContinue
(); - Determine if an enclosed continue would apply to this statement, such as if it is a loop statement.Returns:true if it does
- final bool
usesEH
(); - Returns:true if statement uses exception handling
- final bool
comeFrom
(); - Returns:true if statement 'comes from' somewhere else, like a goto
- final bool
hasCode
(); - Returns:true if statement has executable code.
- Statement
scopeCode
(Scope*sc
, Statement*sentry
, Statement*sexception
, Statement*sfinally
); - 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.Parameters:
Scope* sc
context Statement* sentry
set to code executed upon entry to the scope Statement* sexception
set to code executed upon exit from the scope via exception Statement* sfinally
set to code executed in finally block Returns:code to be run in the finally clause - Statements*
flatten
(Scope*sc
); - Flatten out the scope by presenting the statement as an array of statements.Parameters:
Scope* sc
context Returns:The array of Statements, or null if no flattening necessary - inout pure nothrow inout(Statement)
last
(); - Find last statement in a sequence of statements.Returns:the last statement, or null if there isn't one

(); - A cheaper method of doing downcasting of Statements.Returns:the downcast statement if it can be downcasted, otherwise null

ErrorStatement
: dmd.statement.Statement; - Any Statement that fails semantic() or has a component that is an ErrorExp or a TypeError should return an ErrorStatement from semantic().

CompoundStatement
: dmd.statement.Statement; -
- final this(ref const Loc
loc
, Statements*statements
); - Construct a CompoundStatement using an already existing array of StatementsParameters:
Loc loc
Instantiation information Statements* statements
An array of Statements, that will referenced by this class - final this(ref const Loc
loc
, Statement[]sts
...); - Construct a CompoundStatement from an array of StatementsParameters:
Loc loc
Instantiation information Statement[] sts
A variadic array of Statements, that will copied in this class The entries themselves will not be copied.

CompoundDeclarationStatement

UnrolledLoopStatement
: dmd.statement.Statement; - The purpose of this is so that continue will go to the next of the statements, and break will go to the end of the statements.
- class
ScopeStatement
: dmd.statement.Statement; - class
ForwardingStatement
: dmd.statement.Statement; - Statement whose symbol table contains foreach index variables in a local scope and forwards other members to the parent scope. This wraps a statement.Also see: dmd.attrib.ForwardingAttribDeclaration
- ForwardingScopeDsymbol
sym
; - The symbol containing the static foreach variables.
- Statement
statement
; - The wrapped statement.
- Statements*
flatten
(Scope*sc
); - 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`:static foreach(i; 0 .. 10) scope(exit) writeln(i); writeln("this is printed first"); // then, it prints 10, 9, 8, 7, ...
