    • Method Detail

      • getExpression

        public AstNode getExpression()
        Returns the expression being thrown
      • setExpression

        public void setExpression​(AstNode expression)
        Sets the expression being thrown, and sets its parent to this node.
        Throws:
        java.lang.IllegalArgumentException - } if expression is null
      • 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 thrown expression.
        Specified by:
        visit in class AstNode
        Parameters:
        v - the object to call with this node and its children
