dmd.statement

TypeIdentifier getThrowable();

Returns:

TypeIdentifier corresponding to object.Throwable

TypeIdentifier getException();

Returns:

TypeIdentifier corresponding to object.Exception

enum STMT: ubyte;

Identify Statement types with this enum rather than virtual functions.

abstract class 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

void accept(Visitor v);

Support Visitor Pattern

Parameters:

Visitor v

visitor

inout pure nothrow @nogc inout(ReturnStatement) endsWithReturnStatement();

Does this statement end with a return statement?

I.e. is it a single return statement or some compound statement that unconditionally hits a return statement.

Returns:

return statement it ends with, otherwise null

final inout pure nothrow @nogc inout(ErrorStatement) isErrorStatement();

A cheaper method of doing downcasting of Statements.

Returns:

the downcast statement if it can be downcasted, otherwise null

class 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().

class DtorExpStatement: dmd.statement.ExpStatement;

class CompileStatement: dmd.statement.Statement;

https://dlang.org/spec/statement.html#mixin-statement

class CompoundStatement: dmd.statement.Statement;

final this(ref const Loc loc, Statements* statements);

Construct a CompoundStatement using an already existing array of Statements

Parameters:

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 Statements

Parameters:

Loc loc	Instantiation information
Statement[] sts	A variadic array of Statements, that will copied in this class The entries themselves will not be copied.

class CompoundDeclarationStatement: dmd.statement.CompoundStatement;

class 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, ...
