public ExpressionChainParameters(TSender? Source, Expression? Expression, Expression[] Links, bool BeforeChange, bool SkipInitial, bool IsDistinct, bool SuppressWarnings)

Summary: How one chain of property accesses is to be observed.

Parameters

Name	Type	Description
`Source`	`TSender?`	The root object of the chain.
`Expression`	Expression?	The full expression surfaced on the emitted change.
`Links`	`Expression[]`	The member-access links of the chain, in order.
`BeforeChange`	bool	Whether values are observed before they change.
`SkipInitial`	bool	Whether the initial value is suppressed.
`IsDistinct`	bool	Whether consecutive equal leaf values are suppressed.
`SuppressWarnings`	bool	Whether the warning a property with no notification mechanism raises is suppressed. A binding that already knows a property cannot notify - because it chose this path deliberately - would otherwise log once per subscription for something the caller cannot act on.

Remarks

        Grouped rather than passed one by one: the set travels together through the sink and every level of the
        chain, and each addition to it would otherwise widen several signatures at once.
