Remarks

A provider that watches a data source is told exactly which item changed. Carrying that identity alongside the emission is what lets the delta for the emission be stated rather than rediscovered by comparing the whole new snapshot against the whole previous one.

Constructors

CollectionChange(CollectionChange)

protected CollectionChange(CollectionChange original)

Parameters

original CollectionChange

Parameters
