  • Field Details

    • NULL_PARTITION

      static final String NULL_PARTITION
      Constant used to designate partition values for unpartitioned tables, i.e. "simple" tables. Also used for fully-standalone locations, e.g. for tables persisted or loaded outside of a Database/TableDataService framework.
      See Also:

    • COMPARATOR

      static final Comparator<TableLocationKey> COMPARATOR
      Re-usable Comparator for TableLocationKey objects that disregards the implementation class.

  • Method Details

    • getInternalPartition

      @NotNull CharSequence getInternalPartition()
      Returns:
      The internal partition that encloses the identified table location, or null if none exists

    • getColumnPartition

      @NotNull CharSequence getColumnPartition()
      Returns:
      The column partition that encloses the identified table location, or null if none exists

      static <VALUE_TYPE extends TableLocationKey> io.deephaven.hash.KeyedObjectKey<TableLocationKey,VALUE_TYPE> getKeyedObjectKey()
      Re-usable key object for TableLocationKeys that disregards the implementation class.
