- 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* sccontext Statement* sentryset to code executed upon entry to the scope Statement* sexceptionset to code executed upon exit from the scope via exception Statement* sfinallyset 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* sccontext 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(Visitorv); - Support Visitor PatternParameters:
Visitor vvisitor - 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().

CompoundStatement: dmd.statement.Statement; -
- final this(ref const Loc
loc, Statements*statements); - Construct a CompoundStatement using an already existing array of StatementsParameters:
Loc locInstantiation information Statements* statementsAn 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 locInstantiation information Statement[] stsA 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, ...
