Concrete methods
This method is to Using.apply as flatMap is to Map.
This method is to Using.apply as flatMap is to Map.
Type parameters
- A
-
the underlying type of the result.
- R
-
the resource type.
Value parameters
- f
-
a function of R => Try[A].
- resource
-
a resource which is used by f and will be managed via Using.apply
Attributes
- Returns
-
a Try[A]
Executes the provided function f with a resource managed via Using while handling the resource lifecycle.
Executes the provided function f with a resource managed via Using while handling the resource lifecycle.
This method takes a Try of resource type R and applies the function f to the successfully acquired resource if ry. If ry is a Failure, the failure is propagated.
Type parameters
- A
-
the type of the result produced by the function
f. - R
-
the type of the resource being managed.
Value parameters
- f
-
a function that operates on the resource of type
Rand produces a result of typeA. - ry
-
a
Try[R]representing a resource to be used. IfSuccess, the resource is passed to the functionf.
Attributes
- Returns
-
a
Try[A]containing the result of applyingfto the resource ifryisSuccess, or propagating theFailureifryisFailure.
This method is similar to apply(r), but it takes a Try[R] as its parameter. The definition of f is the same as in the other apply, however.
