interface VariantTable<R,C,V>
A type-variant immutable Table of row key type R, column key type C, and value type V. In the Table, a combination of a row and column key has exactly one value. See the Table documentation and the VariantTable API documentation
Companion namespace: VariantTable
Type parameters
| Name | Description |
|---|---|
| R | the row key type |
| C | the column key type |
| V | the value type |
note
Type-variance means that both the key and value types can be widened in a type-safe way without casting. @note As a consequence of being variant, the type does not contain methods that (can) add new elements to the collection.
