  • Method Details

    • getImplementation

      public Expression getImplementation()
      Description copied from class: Expression
      Type checking may assign a more complex implementation to an innocuous-looking expression (like an identifier). Return that implementation, or the original expression itself if there is no special implementation.

      This appears at present to be dead code, and is not called from within javac. Access to the implementation generally occurs within the same class, and thus uses the underlying field directly.

      Overrides:
      getImplementation in class Expression

    • getOuterArg

      public Expression getOuterArg()
      From the 'this' in an expression of the form outer.this(...), or the 'super' in an expression of the form outer.super(...), return the "outer" expression, or null if there is none.

    • checkValue

      public Vset checkValue(Environment env, Context ctx, Vset vset, Hashtable<Object,Object> exp)
      Check expression
      Overrides:
      checkValue in class Expression

    • isNonNull

      public boolean isNonNull()
      Description copied from class: Expression
      Check if the expression cannot be a null reference.
      Overrides:
      isNonNull in class Expression

    • getAssigner

      public org.glassfish.rmic.tools.tree.FieldUpdater getAssigner(Environment env, Context ctx)
      Description copied from class: Expression
      Return a FieldUpdater object to be used in updating the value of the location denoted by this, which must be an expression suitable for the left-hand side of an assignment. This is used for implementing assignments to private fields for which an access method is required. Returns null if no access method is needed, in which case the assignment is handled in the usual way, by direct access. Only simple assignment expressions are handled here Assignment operators and pre/post increment/decrement operators are are handled by 'getUpdater' below.

      Called during the checking phase.

      Overrides:
      getAssigner in class Expression

    • getUpdater

      public org.glassfish.rmic.tools.tree.FieldUpdater getUpdater(Environment env, Context ctx)
      Description copied from class: Expression
      Return a FieldUpdater object to be used in updating the value of the location denoted by this, which must be an expression suitable for the left-hand side of an assignment. This is used for implementing the assignment operators and the increment/decrement operators on private fields that require an access method, e.g., uplevel from an inner class. Returns null if no access method is needed.

      Called during the checking phase.

      Overrides:
      getUpdater in class Expression

    • inlineValue

      public Expression inlineValue(Environment env, Context ctx)
      Inline
      Overrides:
      inlineValue in class Expression

    • copyInline

      public Expression copyInline(Context ctx)
      Create a copy of the expression for method inlining
      Overrides:
      copyInline in class Expression

    • codeValue

      public void codeValue(Environment env, Context ctx, Assembler asm)
      Code
      Overrides:
      codeValue in class Expression

    • print

      public void print(PrintStream out)
      Print
      Overrides:
      print in class Expression
