Generics on the JVM have an issues with Type Erasure.
Generics on the JVM have an issues with Type Erasure. Basically, Generic types (e.g., Function1[String, Int] and Function1[Double, Bool]) look like the same type to the JVM so that methods cannot be overloaded with generic types. This "marker" trait is used as a work-around to the issue. The marker is implicitly passed as a parameter to some overloaded methods. If you see this as an implicit parameter to an overloaded method, just ignore it.
This trait adds functionality to Scala standard types

RestoringWeakReference contains a scala.ref.WeakReference that,
after it has been nulled out, uses a restorer function to restore the
value.
RestoringWeakReference contains a scala.ref.WeakReference that,
after it has been nulled out, uses a restorer function to restore the
value. This can be used for data that can afford to be evicted by
the garbage collector, but will be needed later. One good example is
Lift form callbacks, which may need the value of an object, but where
you don't necessarily want to be retaining the object indefinitely
while someone is on a page in the face of GC contention.
You can use RestoringWeakReference in a couple of basic ways:
val ref = RestoringWeakReference(() => User.find(id))
In this situation, the RestoringWeakReference will immediately call
the passed function to provide the starting value for the reference,
and then the same function will be used if the reference is evicted.
val ref = RestoringWeakReference(starter, () => User.find(id))
Here, starter is an Option[User] and User.find returns an
Option[User]. The first parameter will be used to initialize the
weak reference, while the function will be used to restore the value
if the reference is evicted.
val baseRef = new WeakReference(starter) val ref = new RestoringWeakReference(baseRef, () => User.find(id))
If you already have a WeakReference instance, you can instantiate
RestoringWeakReference directly and pass that reference as the
starting value, as well.
In all these cases, you use ref.value to get a hold of the value.
That function will return the value if it is available, and, if not,
it will restore the WeakReference and then return the value.

BindHelpers can be used to obtain additional information while a bind call is executing.
BindHelpers can be used to obtain additional information while a bind call is executing.
This informaiton includes node attributes of the current bound node or the entire NodeSeq that is
to be bound. Since the context is created during bind execution and destroyed when bind terminates,
you can benefit of these helpers in the context of FuncBindParam or FuncAttrBindParam. You can
also provide your own implementation of BindParam and your BindParam#calcValue function will be called
in the appropriate context.
Example:
bind("hello", xml,
"someNode" -> {node: NodeSeq => })
In function-body you can safely use BindHelpers methods to obtain correctly-scoped information.
Converts a NodeSeq of a particular format into a ResourceBundle.
Converts a NodeSeq of a particular format into
a ResourceBundle. Basically, each of the second-level
nodes that contain the attribute "name" the name becomes an
entry in the resulting resource bundle. It is possible
to localize each of the entries with the lang and country
attributes which will be compared against the incoming
Locale. If the default attribute is true, then that entry
is used if no others match. Note that language is weighted
more heavily than country.
If the node
is a Text or PCData node, it will be returned as a String.
Otherwise, it will be returned as a NodeSeq.
This CssBind will clear all nodes marked with the class clearable.

Sometimes, you want to do pattern matching against a lazy value.
Sometimes, you want to do pattern matching against a lazy value. Why? Because, there may be parts of the pattern that must be evaluated first and if they evaluate successfully, you then want to test another part of the pattern. Thus, the LZ pattern match.
Function object that can be used in Logger.
Function object that can be used in Logger.setup
Tries to determine which logging backend is available and configures it by using either defaults or a mode-dependent configuration file.
To provide your own configuration, add either a log4j.props file or log4j.xml file to your classpath. If using logback, name it logback.xml
If you want to provide a configuration file for a subset of your application or for a specific environment, Lift expects configuration files to be named in a manner relating to the context in which they are being used. The standard name format is:
modeName.hostName.userName.filename.extension
with hostName and userName being optional, and modeName being one of 'test', 'staging', 'production', 'pilot', 'profile', or 'default. Thus, if you name your log4j config file 'default.log4j.xml' or 'default.log4j.props' it will be picked up correctly.
Utilities for sending email.
