Detailed Description

Represents a generic declaration such as a function declaration.

This class serves as an abstraction for a declaration inside one of the TypeSystems implemented by the language plugins. It does not have any actual logic in it but only stores an opaque pointer and a pointer to the TypeSystem that gives meaning to this opaque pointer. All methods of this class should call their respective method in the TypeSystem interface and pass the opaque pointer along.

Constructor & Destructor Documentation

CompilerDecl() [1/2]

lldb_private::CompilerDecl::CompilerDecl ( )

default

CompilerDecl() [2/2]

lldb_private::CompilerDecl::CompilerDecl ( TypeSystem *  type_system, void *  decl  )

inline

Creates a CompilerDecl with the given TypeSystem and opaque pointer.

This constructor should only be called from the respective TypeSystem implementation.

Clear()

void lldb_private::CompilerDecl::Clear ( )

GetCompilerContext()

std::vector< lldb_private::CompilerContext > CompilerDecl::GetCompilerContext

(

)

const

Populate a valid compiler context from the current declaration.

Returns

A valid vector of CompilerContext entries that describes this declaration. The first entry in the vector is the parent of the subsequent entry, so the topmost entry is the global namespace.
