Data Fields | |
struct pm_scope * | previous |
A pointer to the previous scope in the linked list. | |
pm_locals_t | locals |
The IDs of the locals in the given scope. | |
pm_node_list_t | implicit_parameters |
This is a list of the implicit parameters contained within the block. More... | |
pm_scope_parameters_t | parameters |
This is a bitfield that indicates the parameters that are being used in this scope. More... | |
pm_shareable_constant_value_t | shareable_constant |
The current state of constant shareability for this scope. More... | |
bool | closed |
A boolean indicating whether or not this scope can see into its parent. More... | |
This struct represents a node in a linked list of scopes.
Some scopes can see into their parent scopes, while others cannot.
pm_node_list_t pm_scope::implicit_parameters |
This is a list of the implicit parameters contained within the block.
These will be processed after the block is parsed to determine the kind of parameters node that should be used and to check if any errors need to be added.
pm_scope_parameters_t pm_scope::parameters |
This is a bitfield that indicates the parameters that are being used in this scope.
It is a combination of the PM_SCOPE_PARAMETERS_* constants. There are three different kinds of parameters that can be used in a scope:
If ordinary parameters are being used, then certain parameters can be forwarded to another method/structure. Those are indicated by four additional bits in the params field. For example, some combinations of:
pm_shareable_constant_value_t pm_scope::shareable_constant |
The current state of constant shareability for this scope.
This is changed by magic shareable_constant_value comments.
bool pm_scope::closed |
A boolean indicating whether or not this scope can see into its parent.
If closed is true, then the scope cannot see into its parent.
