Companion object that facilitates the importing of the inside
construct as
an alternative to mixing it in. One use case is to import the inside
construct so you can use
it in the Scala interpreter:

Inspects inside the passed value using the passed partial function.
Inspects inside the passed value using the passed partial function.
The inside
method checks to see whether the partial function passed as the second curried
parameter is defined at the value passed as the first parameter, and if so, passes that value to the
partial function.
If the partial function is not defined at the passed value, inside
will throw a
TestFailedException
with a detail message describing the problem. Otherwise, if the
partial function returns normally, inside
will return normally. If the partial function
completes abruptly with an exception that mixes in ModifiableMessage
(such as
TestFailedException
), inside
will append the value's toString
of
to the exception's detail message, and rethrow it. If the exception thrown by the partial function does not mix
in ModifiableMessage
, inside
completes abruptly with that same exception.
- Value parameters:
- pf
the partial function to use to inspect inside the passed value
- value
the value inside of which to inspect
- Throws:
- TestFailedException
if the passed partial function is not defined at the passed value
