Constructor Detail

### ForInLoop

    public ForInLoop()

### ForInLoop

    public ForInLoop(int pos)

### ForInLoop

    public ForInLoop(int pos,
                     int len)

Method Detail

### getIterator

    public AstNode getIterator()

  Returns loop iterator expression

### setIterator

    public void setIterator(AstNode iterator)

  Sets loop iterator expression: the part before the "in" keyword. Also sets its parent to this node.

  Throws:
    `java.lang.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:
    `java.lang.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

### getInPosition

    public int getInPosition()

  Returns position of "in" keyword

### setInPosition

    public void setInPosition(int inPosition)

  Sets position of "in" keyword

  Parameters:
    `inPosition` - position of "in" 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 java.lang.String toSource(int depth)

  Description copied from class: `AstNode`
  Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

  Note: if the parser was in error-recovery mode, some AST nodes may have `null` children that are expected to be non-`null` when no errors are present. In this situation, the behavior of the `toSource` method is undefined: `toSource` implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

  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
