Member Enumeration Documentation

IsolatedASTKind

enum lldb_private::ScratchTypeSystemClang::IsolatedASTKind

The different kinds of isolated ASTs within the scratch TypeSystem.

These ASTs are isolated from the main scratch AST and are each dedicated to a special language option/feature that makes the contained AST nodes incompatible with other AST nodes.

Enumerator
CppModules	The isolated AST for declarations/types from expressions that imported type information from a C++ module. The templates from a C++ module often conflict with the templates we generate from debug information, so we put these types in their own AST.

GetForTarget() [1/2]

lldb::TypeSystemClangSP lldb_private::ScratchTypeSystemClang::GetForTarget ( Target & target, const clang::LangOptions & lang_opts )

inlinestatic

Returns the scratch TypeSystemClang for the given target.

The returned TypeSystemClang will be the scratch AST or a sub-AST, depending on which fits best to the passed LangOptions.

Parameters

target	The Target which scratch TypeSystemClang should be returned.
lang_opts	The LangOptions of a clang ASTContext that the caller wants to export type information from. This is used to find the best matching sub-AST that will be returned.

GetForTarget() [2/2]

TypeSystemClangSP ScratchTypeSystemClang::GetForTarget ( Target & target, std::optional< IsolatedASTKind > ast_kind = DefaultAST, bool create_on_demand = true )

static

Returns the scratch TypeSystemClang for the given target.

Parameters

target	The Target which scratch TypeSystemClang should be returned.
ast_kind	Allows requesting a specific sub-AST instead of the default scratch AST. See also IsolatedASTKind.
create_on_demand	If the scratch TypeSystemClang instance can be created by this call if it doesn't exist yet. If it doesn't exist yet and this parameter is false, this function returns a nullptr.

Returns

The scratch type system of the target or a nullptr in case an error occurred.
