      public final Expression expr
      The expression to unbox

    • unboxedType

      public final Type unboxedType
      The type that the expression should be unboxed to

  • Constructor Details

    • Unbox

      public Unbox(Expression expr)
      Create an Unbox for an expression
      Parameters:
      expr - The expression to unbox, the unboxed type is derived from the expression type

    • Unbox

      public Unbox(Expression expr, String filename, int lineNumber)
      Create an Unbox for an expression
      Parameters:

      lineNumber - The source line number this expression is associated with

    • Unbox

      public Unbox(Expression expr, Type unboxedType)
      Create an Unbox for an expression
      Parameters:
      expr - The expression to unbox, the unboxed type is derived from the expression type
      unboxedType - The type that the expression should be unboxed to

  • Method Details

    • getType

      public Type getType()
      Description copied from class: Expression
      Get the type returned by this expression
      Specified by:
      getType in class Expression
      Returns:
      The type of this expression

    • reset

      public void reset()
      Description copied from class: Expression
      Resets any labels in expressions so that the method can be regenerated
      Overrides:
      reset in class Expression

    • findCaptured

      public void findCaptured(Environment env)
      Description copied from class: Expression
      Search for local variables that would be captured by a lambda. Each expression has its own implementation of this, because each subexpression must be searched.
      Specified by:
      findCaptured in class Expression
      Parameters:
      env - The environment chain to search

    • convertToFullTailCalls

      public Expression convertToFullTailCalls(boolean inTailPosition)
      Description copied from class: Expression
      Converts this expression to one that is compatible with full tail call optimization
      Specified by:
      convertToFullTailCalls in class Expression
      Parameters:
      inTailPosition - True if this expression is called from the tail position
      Returns:
      A version of this expression whose types are compatible with full tail call optimization

    • generate

      public void generate(ClassGenerator generator, Environment env, boolean inTailPosition)
      Description copied from class: Expression
      Generate the bytecode for this expression
      Specified by:
      generate in class Expression
      Parameters:
      generator - The generator for generating instructions and additional declarations
      env - The environment containing the local variables currently visible to this expression
      inTailPosition - True if this expression is being generated from the tail position of the method
