Protected Attributes | |
Address | m_address |
The variable that this value object is based upon. | |
lldb::TypeSP | m_type_sp |
CompilerType | m_compiler_type |
![]() | |
ValueObject * | m_parent = nullptr |
The parent value object, or nullptr if this has no parent. | |
ValueObject * | m_root = nullptr |
The root of the hierarchy for this ValueObject (or nullptr if never calculated). | |
EvaluationPoint | m_update_point |
Stores both the stop id and the full context at which this value was last updated. | |
ConstString | m_name |
The name of this object. | |
DataExtractor | m_data |
A data extractor that can be used to extract the value. | |
Value | m_value |
Status | m_error |
An error object that can describe any errors that occur when updating values. | |
std::string | m_value_str |
Cached value string that will get cleared if/when the value is updated. | |
std::string | m_old_value_str |
Cached old value string from the last time the value was gotten. | |
std::string | m_location_str |
Cached location string that will get cleared if/when the value is updated. | |
std::string | m_summary_str |
Cached summary string that will get cleared if/when the value is updated. | |
std::string | m_object_desc_str |
Cached result of the "object printer". | |
CompilerType | m_override_type |
If the type of the value object should be overridden, the type to impose. | |
ValueObjectManager * | m_manager = nullptr |
This object is managed by the root object (any ValueObject that gets created without a parent.) The manager gets passed through all the generations of dependent objects, and will keep the whole cluster of objects alive as long as a shared pointer to any of them has been handed out. | |
ChildrenManager | m_children |
std::map< ConstString, ValueObject * > | m_synthetic_children |
ValueObject * | m_dynamic_value = nullptr |
ValueObject * | m_synthetic_value = nullptr |
ValueObject * | m_deref_valobj = nullptr |
lldb::ValueObjectSP | m_addr_of_valobj_sp |
We have to hold onto a shared pointer to this one because it is created as an independent ValueObjectConstResult, which isn't managed by us. | |
