class BlockDecl::Capture

Declaration

class BlockDecl::Capture { /* full declaration omitted */ };

Description

A class which contains all the information about a particular captured value.

Declared at: clang/include/clang/AST/Decl.h:4225

Member Variables

private llvm::PointerIntPair<VarDecl*, 2> VariableAndFlags

The variable being captured.

private clang::Expr* CopyExpr

The copy expression, expressed in terms of a DeclRef (or BlockDeclRef) to the captured variable. Only required if the variable has a C++ class type.

Declared at: clang/include/clang/AST/Decl.h:4265

¶clang::VarDecl* getVariable() const

Description

¶bool hasCopyExpr() const

Declared at: clang/include/clang/AST/Decl.h:4264

¶bool isByRef() const

Description

Whether this is a "by ref" capture, i.e. a capture of a __block variable.

Declared at: clang/include/clang/AST/Decl.h:4250

¶bool isEscapingByref() const

Declared at: clang/include/clang/AST/Decl.h:4252

¶bool isNested() const

Description

Whether this is a nested capture, i.e. the variable captured is not from outside the immediately enclosing function/block.
