class IdTableWithHashBuckets: String to Id table wrapper that assigns out-of-vocabulary keys to buckets.
class InitializableLookupTableBase: Initializable lookup table interface.
class KeyValueTensorInitializer: Table initializers given keys and values tensors.
class LookupInterface: Represent a lookup table that persists across different steps.
class MutableDenseHashTable: A generic mutable hash table implementation using tensors as backing store.
class MutableHashTable: A generic mutable hash table implementation.
class StrongHashSpec: A structure to specify a key of the strong keyed hash spec.
class TableInitializerBase: Base class for lookup table initializers.
class TextFileIdTableInitializer: Table initializer for string to int64 IDs tables from a text file.
class TextFileIndex: The key and value content to get from each line.
class TextFileInitializer: Table initializers from a text file.
class TextFileStringTableInitializer: Table initializer for int64 IDs to string tables from a text file.
