java.lang.Object
org.jfuncmachine.compiler.model.SourceElement
org.jfuncmachine.compiler.model.expr.bool.BooleanExpr
org.jfuncmachine.compiler.model.expr.bool.Result
public class Result extends BooleanExpr
Represents the end point of a boolean expression, containing the expression to be executed depending on whether the boolean test is true or false. This class doesn't actually generate the code to execute the expression, it is more of a placeholder.

  • Constructor Details

    • Result

      public Result(Expression expr)
      Create a new Result for an expression
      Parameters:
      expr - The expression that should be executed if this result is reached

    • Result

      public Result(Expression expr, String filename, int lineNumber)
      Create a new Result for an expression
      Parameters:
      expr - The expression that should be executed if this result is reached
      filename - The source filename this expression is associated with
      lineNumber - The source line number this expression is associated with

  • Method Details

    • invert

      public BooleanExpr invert()
      Description copied from class: BooleanExpr
      Invert this expression, which may involve reversing comparisons or changing and to or with inverted tests, etc.
      Specified by:
      invert in class BooleanExpr
      Returns:
      An inverted boolean expression

    • removeNot

      public BooleanExpr removeNot()
      Description copied from class: BooleanExpr
      Remove any not expressions from a tree of boolean expressions by inverting the expression under the not
      Specified by:
      removeNot in class BooleanExpr
      Returns:
      a BooleanExpr with any nested Not constructions removed

    • reset

      public void reset()
      Description copied from class: BooleanExpr
      Resets any values modified during code generation
      Overrides:
      reset in class BooleanExpr

    • computeSequence

      public BooleanExpr computeSequence(BooleanExpr trueNext, BooleanExpr falseNext, List<BooleanExpr> tests)
      Description copied from class: BooleanExpr
      Compute a sequence of tests to determine if this expression is true or false
      Specified by:
      computeSequence in class BooleanExpr
      Parameters:
      trueNext - The next expression to evaluate if this expression is true
      falseNext - The next expression to evaluate if this expression is false
      tests - An accumulator for the tests to be executed
      Returns:
      The beginning of the sequence
