# DecodeTable

###

#### class DecodeTable[I <: DecodePattern] extends AnyRef

A structured way of generating large decode tables, often found in CPU instruction decoders

Each field is a `DecoderPattern`, its genTable method will be called for each possible pattern and gives expected output for this field as a `BitPat`.

I

### Deprecated Value Members

1.  def formatted(fmtstr: String): String

   Definition Classes

   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

2.  def →[B](y: B): (DecodeTable[I], B)

     @deprecated
   Deprecated

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
