    An object representing the current state of the HTTP request and response.

    An object representing the current state of the HTTP request and response. It uses the DynamicVariable construct such that each thread has its own local session info without passing a huge state construct around. The S object is initialized by LiftSession on request startup.

currentAttr

object currentAttr extends AttrHelper[Box]

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 return Empty.
