  • package ScalaCompat

    Compatibility definitions for Scala 2.13+ vs.

    Compatibility definitions for Scala 2.13+ vs. Scala 2.12 and lesser. This object is conceptually similar to scala.collection.compat. For Scala 2.12 and earlier, it provides a type alias and compatibility functions for LazyList. For Scala 2.13 and greater, it's empty. Thus, all code can use LazyList throughout.

Type Members

  1. trait CanReleaseResource[-T] extends AnyRef

    withResource() needs an implicit evidence parameter of this type to know how to release what's passed to it.

    withResource() needs an implicit evidence parameter of this type to know how to release what's passed to it.

    T

    the type (which must be contravariant to allow, for instance, a T of Closeable to apply to subclasses like InputStream).

    @implicitNotFound( ... )

Value Members

  1. def tryWithResource[T, R](open: ⇒ T)(code: (T) ⇒ R)(implicit mgr: CanReleaseResource[T]): Try[R]

    A version of grizzled.util.withResource that captures any thrown exception, instead of propagating it.

    A version of grizzled.util.withResource that captures any thrown exception, instead of propagating it.

    T

    the type of the resource

    R

    the return type of the code block

    open

    the by-name parameter (code block) to open the resource. This parameter is a by-name parameter so that this function can capture any exceptions it throws.

    code

    the code block to execute with the resource

    mgr

    the resource manager that can release the resource

    returns

    A Success containing the result of the code block, or a Failure with any thrown exception.

  2. def withResource[T, R](resource: T)(code: (T) ⇒ R)(implicit mgr: CanReleaseResource[T]): R

    Ensure that a closeable object is closed.

    Ensure that a closeable object is closed. Note that this function requires an implicit evidence parameter of type CanClose to determine how to close the object. You can implement your own, though common ones are provided automatically.

    Sample use:

    withResource(new java.io.FileInputStream("/path/to/file")) {
    in => ...
}

    Note: If the block throws an exception, withResource propagates the exception. If you want to capture the exception, instead, use grizzled.util.tryWithResource.

    T

    the type of the resource

    R

    the return type of the code block

    resource

    the object that holds a resource to be released

    code

    the code block to execute with the resource

    mgr

    the resource manager that can release the resource

    returns

    whatever the block returns

  3. object CanReleaseResource

    Companion object for CanReleaseResource.

  4. object Implicits
