The IVariable<C, T> type is an interface type applies to ProtoFlux nodes that expose methods to read from and write to some value using only a reference to the node. This allows nodes in the Actions category to read and write to said node using only a link to the node and not any particular field, abstracting away the need to reference specific fields by the user.
The generic arguments designate a context of execution and type of variable. Only action nodes that match the context and type may write to a particular IVariable node.
IVariables are generally invisible to the user when making conventional ProtoFlux, though nodes in the Actions/Indirect category allow one to interface with IVariable types as input, which can be combined with a multiplex for high flexibility of variable management in complex flux.
Conventional variables
These nodes are "conventional" variables within ProtoFlux. They all share the same basic principle of storing a value that one can read from and write to, differing only in their lifetime and syncing:
Other IVariable nodes
Other nodes implement the IVariable interface. These have slightly different effects than the conventional variables:
- Source. When written to, the node writes to the underlying field's value.
- Global To Output. When written to, the node writes to the underlying global's value.
- Field As Variable. When written to, the node writes to the input IValue's value.
- Reference As Variable. When written to, the node writes to the input SyncRef's value.
- User Reference As Variable. When written to, the node writes to the input UserRef's value.
