Class Label

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

    public class Label
    extends Jump
    AST node representing a label. It is a distinct node type so it can record its length and position for code-processing tools. Node type is Token.LABEL.

    • Method Detail

      • getName

        public java.lang.String getName()
        Returns the label text
      • setName

        public void setName​(java.lang.String name)
        Sets the label text
        Throws:
        java.lang.IllegalArgumentException - if name is null or the empty string.
      • 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 Jump
        Parameters:
        depth - the current recursion depth, typically beginning at 0 when called on the root node.
      • visit

        public void visit​(NodeVisitor v)
        Visits this label. There are no children to visit.
        Overrides:
        visit in class Jump
        Parameters:
        v - the object to call with this node and its children
