abstract class BoundedDiagnosingMatcher<S, T : S?>
A matcher that allows for a quick creation of a matcher that applies to a given type but only processes items of a specific subtype of that matcher. Additional interfaces can be applied. This class is syntactic sugar for Matchers#instanceOf(Class) where the first argument is the base class and the remaining optional arguments are interfaces.
| Parameters | |
|---|---|
<S> |
The desired type of the Matcher (T or a subclass of T). |
<T : S?> |
The actual type that the matcher applies safely to. |

fun describeMismatch(item: Any!, mismatchDescription: Description!): Unit
This method provides a default implementation for null check as well as a super type and interface checks provided by the constructor. Failing either check provides a default mismatch description. Passing both will call into matchesSafely which will allow the sub-class to check for a mismatch and describe what went wrong (if anything at all).
| Parameters | |
|---|---|
item: Any! |
The item which is assumed to have mismatched and should be described. |
mismatchDescription: Description! |
The description builder for the mismatch. |
