    • getCondition

      public AstNode getCondition()
      Returns if condition

    • setCondition

      public void setCondition(AstNode condition)
      Sets if condition.
      Throws:
      IllegalArgumentException - if condition is null.

    • getThenPart

      public AstNode getThenPart()
      Returns statement to execute if condition is true

    • setThenPart

      public void setThenPart(AstNode thenPart)
      Sets statement to execute if condition is true
      Throws:
      IllegalArgumentException - if thenPart is null

    • getElsePart

      public AstNode getElsePart()
      Returns statement to execute if condition is false

    • setElsePart

      public void setElsePart(AstNode elsePart)
      Sets statement to execute if condition is false
      Parameters:
      elsePart - statement to execute if condition is false. Can be null.

    • getElsePosition

      public int getElsePosition()
      Returns position of "else" keyword, or -1

    • setElsePosition

      public void setElsePosition(int elsePosition)
      Sets position of "else" keyword, -1 if not present

    • getLp

      public int getLp()
      Returns left paren offset

    • setLp

      public void setLp(int lp)
      Sets left paren offset

    • getRp

      public int getRp()
      Returns right paren position, -1 if missing

    • setRp

      public void setRp(int rp)
      Sets right paren position, -1 if missing

    • setParens

      public void setParens(int lp, int rp)
      Sets both paren positions

    • 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
      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 condition, the then-part, and if supplied, the else-part.
      Specified by:
      visit in class AstNode
      Parameters:
      v - the object to call with this node and its children

    • getElseKeyWordInlineComment

      public AstNode getElseKeyWordInlineComment()

    • setElseKeyWordInlineComment

      public void setElseKeyWordInlineComment(AstNode elseKeyWordInlineComment)
