  • Method Details

    • getResult

      public AstNode getResult()
      Returns result expression node (just after opening bracket)
    • setResult

      public void setResult(AstNode result)
      Sets result expression, and sets its parent to this node.
      Throws:
      IllegalArgumentException - if result is null
    • getLoops

      public List<GeneratorExpressionLoop> getLoops()
      Returns loop list
    • setLoops

      public void setLoops(List<GeneratorExpressionLoop> loops)
      Sets loop list
      Throws:
      IllegalArgumentException - if loops is null
    • addLoop

      public void addLoop(GeneratorExpressionLoop acl)
      Adds a child loop node, and sets its parent to this node.
      Throws:
      IllegalArgumentException - if acl is null
    • getFilter

      public AstNode getFilter()
      Returns filter expression, or null if not present
    • setFilter

      public void setFilter(AstNode filter)
      Sets filter expression, and sets its parent to this node. Can be null.
    • getIfPosition

      public int getIfPosition()
      Returns position of 'if' keyword, -1 if not present
    • setIfPosition

      public void setIfPosition(int ifPosition)
      Sets position of 'if' keyword
    • getFilterLp

      public int getFilterLp()
      Returns filter left paren position, or -1 if no filter
    • setFilterLp

      public void setFilterLp(int lp)
      Sets filter left paren position, or -1 if no filter
    • getFilterRp

      public int getFilterRp()
      Returns filter right paren position, or -1 if no filter
    • setFilterRp

      public void setFilterRp(int rp)
      Sets filter right paren position, or -1 if no filter
    • 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 Scope
      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, the result expression, the loops, and the optional filter.
      Overrides:
      visit in class Scope
      Parameters:
      v - the object to call with this node and its children
