Acquires the resource for the Duration of a given function, The resource will automatically be opened and closed.
Acquires the resource for the Duration of a given function, The resource will automatically be opened and closed. The result will be returned immediately, except in the case of an error. Upon error, the resource will be closed, and then the originating exception will be thrown.
Note: This method will throw the last exception encountered by the managed resource, whatever this happens to be.
A function to execute against the handle returned by the resource
The result of the passed in function
Aquires the resource for the Duration of a given function, The resource will automatically be opened and closed.
Aquires the resource for the Duration of a given function, The resource will automatically be opened and closed. The result will be returned immediately in an Either container. This container will hold all errors, if any occurred during execution, or the resulting value.
A function to execute against the raw resource.
The result of the function (right) or the list of exceptions seen during the processing of the resource (left).
Creates a new resource that is the aggregation of this resource and another.
Creates a new resource that is the aggregation of this resource and another.
The other resource
@return A resource that is a tupled combination of this and that.
This method is used to extract the resource being managed.
This method is used to extract the resource being managed.
This allows you to pull information out of the Managed resource, as such, the Resource will not be "available" after this method call.
@returns An either where the left hand side is the currently contained resource unless exceptions, in which case the right hand side will contain the sequence of throwable encountered.
This method is used to immediately perform operations on a resource while it is open, ensuring the resource is closed before returning.
This method is used to immediately perform operations on a resource while it is open, ensuring the resource is closed before returning.
The transformation function to apply against the raw resource.
A new ManagedResource with the translated type or some other type if an appropriate translator was found.
This method is used to immediately perform operations on a resource while it is open, ensuring the resource is closed before returning.
This method is used to immediately perform operations on a resource while it is open, ensuring the resource is closed before returning. Note: This method *will* open and close the resource, performing the body of the method immediately.

@returns Some(containedValue) if there have been no processing errors, None otherwise
Reflects the resource for use in a continuation.
Reflects the resource for use in a continuation. This method is designed to be used inside a
scala.resource.withResources call.
For example:
import scala.resource._
withResources {
val output = managed(new FileInputStream("output.txt")).reflect[Unit]
for(i <- 1 to 10) {
val input = managed(new FileInputStream("sample"+i+".txt")).reflect[Unit]
input lines foreach (output writeLine _)
}
}
The raw resource, with appropriate continuation-context annotations.
This method creates a Traversable in which all performed methods are done within the context of an "open" resource.
This method creates a Traversable in which all performed methods are done within the context of an "open" resource. Note: Every iteration will attempt to open and close the resource!
A Traversable of elements of type B.

This trait represents a resource that has been modified (or will be modified) inside an ARM block in such a way that the resulting value can be extracted outside of the "ManagedResource" monad. There are two mechanisms for extracting resources. One which returns an optional value, where None is returned if any error occurs during extraction. The other returns an Either where the left side contains any error that occured during extraction and the right side contains the extracted value.
