Class ConditionalExpression

  • All Implemented Interfaces:
    Comparable<AstNode>, Iterable<Node>

    public class ConditionalExpression
    extends AstNode
    AST node representing the ternary operator. Node type is Token.HOOK.
    ConditionalExpression :
            LogicalORExpression ? AssignmentExpression
                                : AssignmentExpression
    ConditionalExpressionNoIn : LogicalORExpressionNoIn LogicalORExpressionNoIn ? AssignmentExpression : AssignmentExpressionNoIn

        public void setColonPosition​(int colonPosition)
        Sets position of : token
        colonPosition - position of : token
      • toSource

        public 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
        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
        v - the object to call with this node and its children
