Detailed Description

Represents a generic declaration context in a program.

A declaration context is data structure that contains declarations (e.g. namespaces).

This class serves as an abstraction for a declaration context 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

CompilerDeclContext() [1/2]

lldb_private::CompilerDeclContext::CompilerDeclContext ( )

default

Constructs an invalid CompilerDeclContext.

CompilerDeclContext() [2/2]

lldb_private::CompilerDeclContext::CompilerDeclContext ( TypeSystem *  type_system, void *  decl_ctx  )

inline

Constructs a CompilerDeclContext with the given opaque decl context and its respective TypeSystem instance.

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

IsClassMethod()

bool CompilerDeclContext::IsClassMethod	(	lldb::LanguageType *	language_ptr,
		bool *	is_instance_method_ptr,
		ConstString *	language_object_name_ptr
	)

Checks if this decl context represents a method of a class.

Parameters

[out]	language_ptr	If non NULL and true is returned from this function, this will indicate if the language that respresents the method.
[out]	is_instance_method_ptr	If non NULL and true is returned from this function, this will indicate if the method is an instance function (true) or a class method (false indicating the function is static, or doesn't require an instance of the class to be called).
[out]	language_object_name_ptr	If non NULL and true is returned from this function, this will indicate if implicit object name for the language like "this" for C++, and "self" for Objective C.

Returns

Returns true if this is a decl context that represents a method in a struct, union or class.

IsContainedInLookup()

bool CompilerDeclContext::IsContainedInLookup

(

CompilerDeclContext

other

)

const

Check if the given other decl context is contained in the lookup of this decl context (for example because the other context is a nested inline namespace).

Parameters

[in]

other

The other decl context for which we should check if it is contained in the lookoup of this context.

Returns

Returns true iff the other decl context is contained in the lookup of this decl context.
