### InfixExpression

    public InfixExpression(AstNode left,
                           AstNode right)

  Constructs a new `InfixExpression`. Updates bounds to include left and right nodes.

### InfixExpression

    public InfixExpression(int operator,
                           AstNode left,
                           AstNode right,
                           int operatorPos)

  Constructs a new `InfixExpression`.

  Parameters:
    `operatorPos` - the absolute position of the operator

Method Detail

### setLeftAndRight

    public void setLeftAndRight(AstNode left,
                                AstNode right)

### getOperator

    public int getOperator()

  Returns operator token – alias for `Node.getType()`

### setOperator

    public void setOperator(int operator)

  Sets operator token – like `Node.setType(int)`, but throws an exception if the operator is invalid.

  Throws:
    `java.lang.IllegalArgumentException` - if operator is not a valid token code

### getLeft

    public AstNode getLeft()

  Returns the left-hand side of the expression

### setLeft

    public void setLeft(AstNode left)

  Sets the left-hand side of the expression, and sets its parent to this node.

  Parameters:
    `left` - the left-hand side of the expression
  Throws:
    `IllegalArgumentException}` - if left is `null`

### getRight

    public AstNode getRight()

  Returns the right-hand side of the expression

  Returns:
    the right-hand side. It's usually an `AstNode` node, but can also be a `FunctionNode` representing Function expressions.

### setRight

    public void setRight(AstNode right)

  Sets the right-hand side of the expression, and sets its parent to this node.

  Throws:
    `IllegalArgumentException}` - if right is `null`

### getOperatorPosition

    public int getOperatorPosition()

  Returns relative offset of operator token

### setOperatorPosition

    public void setOperatorPosition(int operatorPosition)

  Sets operator token's relative offset

  Parameters:
    `operatorPosition` - offset in parent of operator token

### hasSideEffects

    public boolean hasSideEffects()

  Overrides:
    `hasSideEffects` in class `AstNode`

### 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.

  Specified by:
    `toSource` in class `AstNode`
  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 left operand, and the right operand.

  Specified by:
    `visit` in class `AstNode`
  Parameters:
    `v` - the object to call with this node and its children
