`class Pointer`

Represents a pointer type. This includes regular pointers, block pointers, Objective-C object pointers, and member pointers.

Definitions

`def pointee`

Get the type that this pointer points to.

Signature

returns　Type: The pointee type.

Implementation

def pointee
	Type.create Lib.get_pointee_type(@type), @translation_unit
end

`def function?`

Check if this is a function pointer.

Signature

returns　Boolean: True if this pointer points to a function.

Implementation

def function?
	self.pointee.is_a?(Types::Function)
end

`def class_type`

Get the class type for member pointers.

Signature

returns　Type, nil: The class type if this is a member pointer, nil otherwise.

Implementation

def class_type
	if self.kind == :type_member_pointer
		Type.create Lib.type_get_class_type(@type), @translation_unit
	else
		nil
	end
end

`def forward_declaration?`

Check if this pointer references a forward declaration.

Signature

returns　Boolean: True if this pointer points to a forward-declared type.

Implementation

def forward_declaration?
	# Is this a pointer to a record (struct or union) that referenced
	# a forward declaration at the point of its inclusion in the translation unit?
	if !self.function? && self.pointee.is_a?(Types::Elaborated) &&
			self.pointee.canonical.is_a?(Types::Record)
		
		# Get the universal symbol reference
		usr = self.pointee.canonical.declaration.usr
		
		# Now does that same usr occur earlier in the file?
		first_declaration, _ = self.translation_unit.cursor.find do |child, parent|
			child.usr == usr
		end
		# NOTE - Maybe should also check that the line number of
		# is less than the line number of the declaration this type references
		first_declaration.forward_declaration?
	end
end
