  • Method Details

    • getIterator

      public AstNode getIterator()
      Returns loop iterator expression

    • setIterator

      public void setIterator(AstNode iterator)
      Sets loop iterator expression: the part before the "in" or "of" keyword. Also sets its parent to this node.
      Throws:
      IllegalArgumentException - if iterator is null

    • getIteratedObject

      public AstNode getIteratedObject()
      Returns object being iterated over

    • setIteratedObject

      public void setIteratedObject(AstNode object)
      Sets object being iterated over, and sets its parent to this node.
      Throws:
      IllegalArgumentException - if object is null

    • isForEach

      public boolean isForEach()
      Returns whether the loop is a for-each loop

    • setIsForEach

      public void setIsForEach(boolean isForEach)
      Sets whether the loop is a for-each loop

    • isForOf

      public boolean isForOf()
      Returns whether the loop is a for-of loop

    • setIsForOf

      public void setIsForOf(boolean isForOf)
      Sets whether the loop is a for-each loop

    • getInPosition

      public int getInPosition()
      Returns position of "in" or "of" keyword

    • setInPosition

      public void setInPosition(int inPosition)
      Sets position of "in" or "of" keyword
      Parameters:
      inPosition - position of "in" or "of" keyword, or -1 if not present (e.g. in presence of a syntax error)

    • getEachPosition

      public int getEachPosition()
      Returns position of "each" keyword

    • setEachPosition

      public void setEachPosition(int eachPosition)
      Sets position of "each" keyword
      Parameters:
      eachPosition - position of "each" keyword, or -1 if not present.

    • toSource

      public String toSource(int depth)
      Description copied from class: Jump
      Jumps are only used directly during code generation, and do not support this interface.
      Overrides:
      toSource in class Scope
      Parameters:
      depth - the current recursion depth, typically beginning at 0 when called on the root node.

    • visit

      public void visit(NodeVisitor v)
      Visits this node, the iterator, the iterated object, and the body.
      Overrides:
      visit in class Scope
      Parameters:
      v - the object to call with this node and its children
