      Returns the number of local variable slots consumed by this type.
      Returns:
      the number of local variable slots consumed by this type
    • asLoadable

      public TypeKindPREVIEW asLoadable()
      Erase this type kind to the type which will be used for xLOAD, xSTORE, and xRETURN bytecodes

      Parameters:
      newarraycode - the operand of the newarray instruction
      Returns:
      the type kind associated with the array type described by the array code used as an operand to newarray
