Foreach

case class Foreach(name: String, array: Expression, body: Seq[Expression], seq: Boolean, pos: Option[String] = scala.None) extends Expression with Product with Serializable

Abstract syntax tree for a foreach loop.

name

new variable name for array items

array

expression that evaluates to an array

body

expressions to evaluate for each item of the array

seq

if false, seal the scope from above and allow implementations to parallelize (Hadrian doesn't)

pos

source file location from the locator mark

    Walk over tree applying a Task while checking for semantic errors.

    This is how Java is generated from an abstract syntax tree: the Task in that case is JVMCompiler.

    functionTable

    used to look up functions

    engineOptions

    implementation options

    version

    version of the PFA language in which to interpret this PFA

    returns

    (information about this abstract syntax tree node after type-checking, result of the generic task)
