Class Compiler

java.lang.Object
  orc.ast.oil.Compiler

All Implemented Interfaces:

Visitor<Node>

public final class Compiler
extends java.lang.Object
implements Visitor<Node>

Compiles an oil syntax tree into an execution graph. Every node is compiled relative to an "output" node that represents the "rest of the program". Thus the tree of compiled nodes is created bottom up.
