- def addAround(lw: LoanWrapper): Unit
You can wrap the handling of an HTTP request with your own wrapper.
You can wrap the handling of an HTTP request with your own wrapper. The wrapper can execute code before and after the request is processed (but still have S scope). This allows for query analysis, etc. Wrappers are chained, much like servlet filters, so you can layer processing on the request. As an example, let's look at a wrapper that opens a resource and makes it available via a RequestVar, then closes the resource when finished:
import net.liftweb.http.{ ResourceVar,S } import net.liftweb.util.LoanWrapper // Where "ResourceType" is defined by you object myResource extends ResourceVar[ResourceType](...) class Boot { def boot { ... S.addAround( new LoanWrapper { def apply[T](f: => T) : T = { myResource(... code to open and return a resource instance ...) f() // This call propagates the request further down the "chain" for template processing, etc. myResource.is.close() // Release the resource } } ) ... } }This method is *NOT* intended to change the generated HTTP request or to respond to requests early. LoanWrappers are there to set up and take down state *ONLY*. The LoanWrapper may be called outside the scope of an HTTP request (e.g., as part of an Actor invocation).- See also

Adds a Cookie to the List[Cookies] that will be sent with the Response.
If you wish to delete a Cookie as part of the Response, use the deleteCookie method.
An example of adding and removing a Cookie is:

- def addHighLevelSessionDispatcher(name: String, disp: DispatchPF): Box[HashMap[String, DispatchPF]]
Adds a dispatch function for the current session, as opposed to a global dispatch through LiftRules.dispatch.
Adds a dispatch function for the current session, as opposed to a global dispatch through LiftRules.dispatch. An example would be if we wanted a user to be able to download a document only when logged in. First, we define a dispatch function to handle the download, specific to a given user:
def getDocument(userId : Long)() : Box[LiftResponse] = { ... }Then, in the login/logout handling snippets, we could install and remove the custom dispatch as appropriate:
def login(xhtml : NodeSeq) : NodeSeq = { def doAuth () { ... if (user.loggedIn_?) { S.addHighLevelSessionDispatcher("docDownload", { case Req(List("download", "docs"), _, _) => getDocument(user.id) } ) } } def logout(xhtml : NodeSeq) : NodeSeq = { def doLogout () { ... S.removeHighLevelSessionDispatcher("docDownload") // or, if more than one dispatch has been installed, this is simpler S.clearHighLevelSessionDispatcher } }It's important to note that per-session dispatch takes precedence over LiftRules.dispatch, so you can override things set there.
- name
A name for the dispatch. This can be used to remove it later by name.
- disp
The dispatch partial function

- def addSessionRewriter(name: String, rw: RewritePF): Box[HashMap[String, RewritePF]]
Adds a per-session rewrite function.
Adds a per-session rewrite function. This can be used if you only want a particular rewrite to be valid within a given session. Per-session rewrites take priority over rewrites set in LiftRules.rewrite, so you can use this mechanism to override global functionality. For example, you could set up a global rule to make requests for the "account profile" page go back to the home page by default:
package bootstrap.liftweb ... imports ... class Boot { def boot { LiftRules.rewrite.append { case RewriteRequest(ParsePath(List("profile")), _, _, _) => RewriteResponse(List("index")) } } }Then, in your login snippet, you could set up a per-session rewrite to the correct template:
def loginSnippet (xhtml : NodeSeq) : NodeSeq = { ... def doLogin () { ... S.addSessionRewriter("profile", { case RewriteRequest(ParsePath(List("profile")), _, _, _) => RewriteResponse(List("viewProfile"), Map("user" -> user.id)) } ... } ... }And in your logout snippet you can remove the rewrite:
def doLogout () { S.removeSessionRewriter("profile") // or S.clearSessionRewriter }- name
A name for the rewrite function so that it can be replaced or deleted later.
- rw
The rewrite partial function

- def attrs: List[(Either[String, (String, String)], String)]
Get a list of current attributes.
Get a list of current attributes. Each attribute item is a pair of (key,value). The key is an Either that depends on whether the attribute is prefixed or not. If the attribute is prefixed, the key is a Right((prefix, name)). If the attribute is unprefixed then the key is a Left(name). For example, the following table shows how various tag attributes would be represented:
Snippet Tag Parsed attrs <lift:MySnippet testname="test" /> List((Left("testname"), "test")) <lift:MySnippet anchor:name="test" /> List((Right(("anchor", "name")), "test")) The prefixedAttrsToMap method provides a convenient way to retrieve only attributes with a given prefix. The prefixedAttrsToMetaData method can be used to add attributes onto an XML node

- def attrsFlattenToMap: Map[String, String]
Converts the S.attrs to a Map[String, String].
Converts the S.attrs to a Map[String, String]. The key of the map depends on whether the attribute is prefixed or not.

Converts S.attrs attributes to a MetaData object that can be used to add attributes to one or more XML elements. Similar to prefixedAttrsToMetaData, except that it handles both prefixed and unprefixed attributes. This version of the method will use all of the currently set attributes from S.attrs. If you want to filter it, use the attrsToMetaData(String => Boolean) version, which allows you to specify a predicate function for filtering. For example, if you want all of the current attributes to be added to a div tag, you could do:
val myDiv = ( {...} ) % S.attrsToMetaData- returns
a MetaData instance representing all attributes in S.attrs

- def logQuery(query: String, time: Long): ListBuffer[(String, Long)]
Log a query for the given request.
Log a query for the given request. The query log can be tested to see if queries for the particular page rendering took too long. The query log starts empty for each new request. net.liftweb.mapper.DB.queryCollector is a method that can be used as a log function for the net.liftweb.mapper.DB.addLogFunc method to enable logging of Mapper queries. You would set it up in your bootstrap like:
import net.liftweb.mapper.DB import net.liftweb.http.S class Boot { def boot { ... DB.addLogFunc(DB.queryCollector) ... } }Note that the query log is simply stored as a List and is not sent to any output by default. To retrieve the List of query log items, use S.queryLog. You can also provide your own analysis function that will process the query log via S.addAnalyzer.

Attaches to this uri and parameter that has function f associated with. When this request is submitted to server the function will be executed and then it is automatically cleaned up from functions caches.
- def mapSnippet(name: String, func: (NodeSeq) => NodeSeq): Unit
Associates a name with a snippet function 'func'.
Associates a name with a snippet function 'func'. This can be used to change a snippet mapping on a per-request basis. For example, if we have a page that we want to change behavior on based on query parameters, we could use mapSnippet to programmatically determine which snippet function to use for a given snippet in the template. Our code would look like:
import scala.xml.{ NodeSeq,Text } class SnipMap { def topSnippet (xhtml : NodeSeq) : NodeSeq = { if (S.param("showAll").isDefined) { S.mapSnippet("listing", listing) } else { S.mapSnippet("listing", { ignore => Text("") } ) } ... } def listing(xhtml : NodeSeq) : NodeSeq = { ... }Then, your template would simply look like:
<lift:surround with="default" at="content"> ... <p><lift:SnipMap.topSnippet /></p> <p><lift:listing /></p> </lift:surround>
Snippets are processed in the order that they're defined in the template, so if you want to use this approach make sure that the snippet that defines the mapping comes before the snippet that is being mapped. Also note that these mappings are per-request, and are discarded after the current request is processed.
- name
The name of the snippet that you want to map (the part after "<lift:").
- func
The snippet function to map to.
- def mapSnippetsWith[T](snips: (String, (NodeSeq) => NodeSeq)*)(f: => T): T

- def withAttrs[T](attrs: MetaData)(f: => T): T
Temporarily adds the given attributes to the current set, then executes the given function.
Temporarily adds the given attributes to the current set, then executes the given function.
- attrs
The attributes to set temporarily
- def withCurrentSnippetNodeSeq[T](ns: NodeSeq)(f: => T): T

- returns
the value the the expression returns
- object attr extends AttrHelper[Box]
Used to get an attribute by its name.
Used to get an attribute by its name. There are several means to getting attributes:
// Get a Box for the attribute: val myAttr = S.attr("test") openOr "Not found" // Get an attribute or return a default value: val myAttr = S.attr("name", "Fred") // Apply a transform function on the attribute value, or return an Empty: val pageSize = S.attr("count", _.toInt) openOr 20 // There are also prefixed versions: val prefixedAttr = S.attr("prefix", "name") openOr "Not found"Note that this uses the data held in S.attrs, which means that it will find attributes through the entire snippet nesting stack. For example, given the snippets:
<lift:MyStuff.snippetA foo="bar"> <lift.MyStuff.snippetB>...</lift.MyStuff.snippetB> </lift:MyStuff.snippetA>
Calling
S.attr("foo")from snippetB will returnFull("bar"). - object currentAttr extends AttrHelper[Box]
Used to get an attribute by its name from the current snippet element.
Used to get an attribute by its name from the current snippet element. There are several means to getting attributes:
// Get a Box for the attribute: val myAttr = S.currentAttr("test") openOr "Not found" // Get an attribute or return a default value: val myAttr = S.currentAttr("name", "Fred") // Apply a transform function on the attribute value, or return an Empty: val pageSize = S.currentAttr("count", _.toInt) openOr 20 // There are also prefixed versions: val prefixedAttr = S.currentAttr("prefix", "name") openOr "Not found"Note that this uses the data held in S.currentAttrs, which means that it will only find attributes from the current snippet element. For example, given the snippets:
<lift:MyStuff.snippetA foo="bar"> <lift.MyStuff.snippetB>...</lift.MyStuff.snippetB> </lift:MyStuff.snippetA>
Calling
S.currentAttr("foo")from snippetB will returnEmpty.
