Additional Inherited Members | |
| Protected Attributes inherited from AbstractQoreNode | |
| bool | custom_reference_handlers: 1 |
| set to one for objects that need custom reference handlers | |
| bool | needs_eval_flag: 1 |
| if this is true then the type can be evaluated | |
| bool | there_can_be_only_one: 1 |
| if this is set to true, then reference counting is turned off for objects of this class | |
| qore_type_t | type: 11 |
| the type of the object More... | |
| bool | value: 1 |
| this is true for values, if false then either the type needs evaluation to produce a value or is a parse expression | |
| Protected Attributes inherited from QoreReferenceCounter | |
| QoreThreadLock | mRO |
| pthread lock to ensure atomicity of updates for architectures where we don't have an atomic increment and decrement implementation | |
