  • Method Details

    • getBreakLabel

      public Name getBreakLabel()
      Returns the intended label of this break statement
      Returns:
      the break label. null if the source code did not specify a specific break label via "break <target>".
    • setBreakLabel

      public void setBreakLabel(Name label)
      Sets the intended label of this break statement, e.g. 'foo' in "break foo". Also sets the parent of the label to this node.
      Parameters:
      label - the break label, or null if the statement is just the "break" keyword by itself.
    • getBreakTarget

      public AstNode getBreakTarget()
      Returns the statement to break to
      Returns:
      the break target. Only null if the source code has an error in it.
    • setBreakTarget

      public void setBreakTarget(Jump target)
      Sets the statement to break to.
      Parameters:
      target - the statement to break to
      Throws:
      IllegalArgumentException - if target is null
    • 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.

      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 node, then visits the break label if non-null.
      Overrides:
      visit in class Jump
      Parameters:
      v - the object to call with this node and its children
