This method is used to cast the receiver object to be of type T0.
This method is used to cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expressionList(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as
part of compilation it is not possible to check whether the contents of the list are of the requested typed.

Converts a boxed boolean into a response of a root element with no contents and the "success" attribute set to the value of the "in" parameter.
Converts a boxed boolean into a response of a root element with no contents and the "success" attribute set to the value of the "in" parameter. If the Box is a Failure, the "msg" attribute of the root element will be set to the Failure's msg value.
Converts a boxed Seq[Node] into a response.
Converts a boxed Seq[Node] into a response. If the Box is a Full, the root element uses the contents of the Box as its contents, and sets the "success" attribute to "true". If the Box is a Failure, the "success" attribute is set to "false" and the "msg" attribute is set to the Failure's msg value. If the Box is Empty then the root element is returned with no contents and the "success" attribute set to "false".

The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef:
* It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true.
* It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and
only if y.eq(x) returns true.
* It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.
Additionally, the eq method has three other properties.
* It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.
* For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
* null.eq(null) returns true.
When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

true if the argument is a reference to the receiver object; false otherwise.
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence
relation]:
* It is reflexive: for any instance x of type Any, x.equals(x) should return true.
* It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and
only if y.equals(x) returns true.
* It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and
y.equals(z) returns true, then x.equals(z) should return true.
If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects
that are "equal" (o1.equals(o2) returns true) hash to the same
scala.Int
(o1.hashCode.equals(o2.hashCode)).

This method is called by the garbage collector on the receiver object when garbage collection determines that there are no more references to the object.

Returns a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet
not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0.
However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure
to verify that the behavior is consistent with the equals method.

This method is used to test whether the dynamic type of the receiver object is T0.
This method is used to test whether the dynamic type of the receiver object is T0.
Note that the test result of the test is modulo Scala's erasure semantics. Therefore the expression1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will
return true. In the latter example, because the type argument is erased as part of compilation it is not
possible to check whether the contents of the list are of the requested typed.

Mix this trait into your REST service provider to convert between different response types and a LiftResponse. You need to define the createTag method to provide a root element for your API. You may optionally override the successAttrName, operationAttrName, and/or msgAttrName defs to control the attributes that will be applied to your root element based on the return from your API.
For example, the following code implements a simple API that takes a comma- separated string of integers and reduces them with various operations.
object CalculatorApi extends XmlApiHelper { // Define our root tag def createTag(contents : NodeSeq) : Elem = <api>{contents}</api>// The LiftResponses here will be converted to Box[LiftResponse] // via the putResponseInBox implicit conversion def calculator : LiftRules.DispatchPF = { case r @ Req(List("api","sum"), _, GetRequest) => () => doSum(r) case r @ Req(List("api","product"), _, GetRequest) => () => doProduct(r) case r @ Req(List("api","max"), _, GetRequest) => () => doMax(r) case r @ Req(List("api","min"), _, GetRequest) => () => doMin(r) case Req("api" :: _, _, _) => () => BadResponse() }
// Define a common handler def reduceOp (operation : (Int,Int) => Int)(r : Req) : Box[Elem] = tryo { (r.param("args").map { args => <result>{args.split(",").map(_.toInt).reduceLeft(operation)}</result> }) ?~ "Missing args" } match { case Full(x) => x case f : Failure => f case Empty => Empty }
// Using a return type of LiftResponse causes the canNodeToResponse // implicit to be invoked def doSum (r : Req) : LiftResponse = reduceOp(_ + _)(r) def doProduct (r : Req) : LiftResponse = reduceOp(_ * _)(r) def doMax (r : Req) : LiftResponse = reduceOp(_ max _)(r) def doMin (r : Req) : LiftResponse = reduceOp(_ min _)(r) }
