5.  def assertTableReadable(protocol: Protocol, metadata: Metadata): Unit

   Asserts that the given table doesn't contain any unsupported type changes.

   Asserts that the given table doesn't contain any unsupported type changes. This should never happen unless a non-compliant writer applied a type change that is not part of the feature specification.

   Checks that the type widening table property wasn't disabled or enabled between the two given states, throws an errors if it was.

10.  def filterFilesRequiringRewrite(snapshot: Snapshot, files: Seq[AddFile]): Seq[AddFile]

    Filter the given list of files to only keep files that were written before the latest type change, if any.

    Filter the given list of files to only keep files that were written before the latest type change, if any. These older files contain a column or field with a type that is different than in the current table schema and must be rewritten when dropping the type widening table feature to make the table readable by readers that don't support the feature.

14.  def isEnabled(protocol: Protocol, metadata: Metadata): Boolean

    Returns whether Type Widening is enabled on this table version.

    Returns whether Type Widening is enabled on this table version. Checks that Type Widening is supported, which is a pre-requisite for enabling Type Widening, throws an error if not. When Type Widening is enabled, the type of existing columns or fields can be widened using ALTER TABLE CHANGE COLUMN.

15.  final def isInstanceOf[T0]: Boolean

    Any

16.  def isSupported(protocol: Protocol): Boolean

    Returns whether the protocol version supports the Type Widening table feature.

17.  def isTypeChangeSupported(fromType: AtomicType, toType: AtomicType): Boolean

    Returns whether the given type change is eligible for widening.

    Returns whether the given type change is eligible for widening. This only checks atomic types. It is the responsibility of the caller to recurse into structs, maps and arrays.

18.  def isTypeChangeSupportedForSchemaEvolution(fromType: AtomicType, toType: AtomicType): Boolean

    Returns whether the given type change can be applied during schema evolution.

    Returns whether the given type change can be applied during schema evolution. Only a subset of supported type changes are considered for schema evolution.
