4.  val USER_SPECIFIED_CAST: TreeNodeTag[Boolean]

5.  final def asInstanceOf[T0]: T0

6.  def canANSIStoreAssign(from: DataType, to: DataType): Boolean

   Returns true iff we can cast the from type to to type as per the ANSI SQL.

   Returns true iff we can cast the from type to to type as per the ANSI SQL. In practice, the behavior is mostly the same as PostgreSQL. It disallows certain unreasonable type conversions such as converting string to int or double to boolean.

7.  def canCast(from: DataType, to: DataType): Boolean

   Returns true iff we can cast from type to to type.

8.  def canNullSafeCastToDecimal(from: DataType, to: DecimalType): Boolean
9.  def canUpCast(from: DataType, to: DataType): Boolean

   Returns true iff we can safely up-cast the from type to to type without any truncating or precision lose or possible runtime failures.

   Returns true iff we can safely up-cast the from type to to type without any truncating or precision lose or possible runtime failures. For example, long -> int, string -> int are not up-cast.

14.  def forceNullable(from: DataType, to: DataType): Boolean

    Returns true if casting non-nullable values from from type to to type may return null.

    Returns true if casting non-nullable values from from type to to type may return null. Note that the caller side should take care of input nullability first and only call this method if the input is not nullable.
