    • allowsReinterpret

      public <ALTERNATE_DATA_TYPE> boolean allowsReinterpret(@NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)
      Description copied from interface: ColumnSource
      Test if a reinterpret call will succeed.
      Specified by:
      allowsReinterpret in interface ColumnSource<T>
      Overrides:
      allowsReinterpret in class AbstractColumnSource<T>
      Type Parameters:
      ALTERNATE_DATA_TYPE - the dataType to inquire about
      Parameters:
      alternateDataType - The alternative type to consider
      Returns:
      If a reinterpret on this column source with the supplied alternateDataType will succeed.

    • doReinterpret

      protected <ALTERNATE_DATA_TYPE> ColumnSource<ALTERNATE_DATA_TYPE> doReinterpret(@NotNull Class<ALTERNATE_DATA_TYPE> alternateDataType)
      Description copied from class: AbstractColumnSource
      Supply allowed reinterpret results. The default implementation handles the most common case to avoid code duplication.
      Overrides:
      doReinterpret in class AbstractColumnSource<T>
      Type Parameters:
      ALTERNATE_DATA_TYPE - the dataType to reinterpret to
      Parameters:
      alternateDataType - The alternate data type
      Returns:
      The resulting ColumnSource

    • hasSymbolTable

      public boolean hasSymbolTable(@NotNull ReadOnlyIndex sourceIndex)
      Specified by:
      hasSymbolTable in interface SymbolTableSource<T>
      Parameters:
      sourceIndex - The Index whose keys must be mappable
      Returns:
      Whether this SymbolTableSource can provide a symbol table that covers all keys in sourceIndex.

    • asDictionary

      public RegionedColumnSource<T> asDictionary()

    • getStaticSymbolTable

      public QueryTable getStaticSymbolTable(@NotNull ReadOnlyIndex sourceIndex, boolean useLookupCaching)
      Description copied from interface: SymbolTableSource

      Get a static Table view of this SymbolTableSource's symbol table, providing a many:1 or 1:1 mapping of unique long identifiers to the symbol values in this source.

      Specified by:
      getStaticSymbolTable in interface SymbolTableSource<T>
      Parameters:
      sourceIndex - The Index whose keys must be mappable via the result Table's identifier column
      useLookupCaching - Whether symbol lookups performed to generate the symbol table should apply caching
      Returns:
      The symbol table

    • getSymbolTable

      public final Table getSymbolTable(@NotNull QueryTable sourceTable, boolean useLookupCaching)
      Description copied from interface: SymbolTableSource

      Get a Table view of this SymbolTableSource's symbol table, providing a many:1 or 1:1 mapping of unique long identifiers to the symbol values in this source.

      The result will be refreshing if table is a refreshing DynamicTable.

      Specified by:
      getSymbolTable in interface SymbolTableSource<T>
      Parameters:
      sourceTable - The QueryTable whose Index keys must be mappable via the result Table's identifier column
      useLookupCaching - Whether symbol lookups performed to generate the symbol table should apply caching
      Returns:
      The symbol table

    • addRegion
