Performs an operation using a Manager, then closes the Manager,
releasing its resources (in reverse order of acquisition).
Performs an operation using a Manager, then closes the Manager,
releasing its resources (in reverse order of acquisition).
Example:
val lines = Using.Manager { use =>
use(new BufferedReader(new FileReader("file.txt"))).lines()
}If using resources which require an implicit Manager as a parameter,
this method should be invoked with an implicit modifier before the function
parameter:
Example:
val lines = Using.Manager { implicit use =>
new SafeFileReader("file.txt").lines()
}See the main doc for Using for full details of suppression behavior.
