Constructor Detail

### ConditionalExpression

    public ConditionalExpression()

### ConditionalExpression

    public ConditionalExpression(int pos)

### ConditionalExpression

    public ConditionalExpression(int pos,
                                 int len)

Method Detail

### getTestExpression

    public AstNode getTestExpression()

  Returns test expression

### setTestExpression

    public void setTestExpression(AstNode testExpression)

  Sets test expression, and sets its parent.

  Parameters:
    `testExpression` - test expression
  Throws:
    `java.lang.IllegalArgumentException` - if testExpression is `null`

### getTrueExpression

    public AstNode getTrueExpression()

  Returns expression to evaluate if test is true

### setTrueExpression

    public void setTrueExpression(AstNode trueExpression)

  Sets expression to evaluate if test is true, and sets its parent to this node.

  Parameters:
    `trueExpression` - expression to evaluate if test is true
  Throws:
    `java.lang.IllegalArgumentException` - if expression is `null`

### getFalseExpression

    public AstNode getFalseExpression()

  Returns expression to evaluate if test is false

### setFalseExpression

    public void setFalseExpression(AstNode falseExpression)

  Sets expression to evaluate if test is false, and sets its parent to this node.

  Parameters:
    `falseExpression` - expression to evaluate if test is false
  Throws:
    `java.lang.IllegalArgumentException` - if `falseExpression` is `null`

### getQuestionMarkPosition

    public int getQuestionMarkPosition()

  Returns position of ? token

### setQuestionMarkPosition

    public void setQuestionMarkPosition(int questionMarkPosition)

  Sets position of ? token

  Parameters:
    `questionMarkPosition` - position of ? token

### getColonPosition

    public int getColonPosition()

  Returns position of : token

### setColonPosition

    public void setColonPosition(int colonPosition)

  Sets position of : token

  Parameters:
    `colonPosition` - position of : 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, then the test-expression, the true-expression, and the false-expression.

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