Description
Pair between the output location and its notifier.
TLocationRec is a record that makes a pair between the output location and its notifier. TLocationRec contains the following fields:
| Field | Meaning |
Location
|
The location to which the output value is set. |
Notifier
|
Notifier associated with the location, used to notify the system that the object member wrapped by the location has changed. |
CompiledBinding
|
Maintains a reference to the output compiled expression that generated the location. CompiledBinding is necessary because the internal wrappers are structured in such a way that they depend on information sustained only by a reference to System.Bindings.EvalProtocol.ICompiledBinding. Keep in mind that locations that are not generated by output expressions have this parameter set to nil.
|
Scope
|
Keeps a reference to the input scope used by the output compiled expression. The scope is necessary in case the expression may be reevaluated at certain points. Keep in mind that locations that are not generated by output expressions have this parameter set to nil. |
