  • Method Details

    • isImmutable

      public boolean isImmutable()
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Reports whether the value is deeply immutable.
      Specified by:
      isImmutable in interface org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Returns:
      whether this value and all values reachable from it are immutable

    • name

      public String name()
      Returns the HMAC algorithm name.
      Returns:
      hmac- followed by the digest name

    • digestSize

      public int digestSize()
      Returns the size of this HMAC result.
      Returns:
      the output length in bytes

    • blockSize

      public int blockSize()
      Returns the underlying digest algorithm block size.
      Returns:
      the block size in bytes

    • update

      public void update(Object msg) throws org.microproxy.thirdparty.starlark.eval.EvalException
      Feeds additional bytes into this HMAC object.
      Parameters:
      msg - the Starlark bytes to append
      Throws:
      org.microproxy.thirdparty.starlark.eval.EvalException - if the object is frozen or the input is not bytes

    • digest

      public org.microproxy.thirdparty.starlark.eval.StarlarkBytes digest() throws org.microproxy.thirdparty.starlark.eval.EvalException
      Computes the HMAC of bytes fed so far without changing this object.
      Returns:
      the result as immutable bytes
      Throws:
      org.microproxy.thirdparty.starlark.eval.EvalException - if the JDK provider cannot copy its state

    • hexdigest

      public String hexdigest() throws org.microproxy.thirdparty.starlark.eval.EvalException
      Computes the HMAC as hexadecimal without changing this object.
      Returns:
      the lowercase hexadecimal result
      Throws:
      org.microproxy.thirdparty.starlark.eval.EvalException - if the JDK provider cannot copy its state

    • copy

      public HashlibModule.HmacObject copy(org.microproxy.thirdparty.starlark.eval.StarlarkThread thread) throws org.microproxy.thirdparty.starlark.eval.EvalException
      Copies the accumulated state into an independent HMAC object.
      Parameters:
      thread - the calling thread that owns the copy
      Returns:
      a mutable copy of this object
      Throws:
      org.microproxy.thirdparty.starlark.eval.EvalException - if the JDK provider cannot copy its state

    • repr

      public void repr(org.microproxy.thirdparty.starlark.eval.Printer printer, org.microproxy.thirdparty.starlark.eval.StarlarkSemantics semantics)
      Description copied from interface: org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Prints an official representation of object x.

      Convention is that the string should be parseable back to the value x. If this isn't feasible then it should be a short human-readable description enclosed in angled brackets, e.g. "<foo object>".

      Specified by:
      repr in interface org.microproxy.thirdparty.starlark.eval.StarlarkValue
      Parameters:
      printer - a printer to be used for formatting nested values.
      semantics - the interpreter settings used to format nested values
