  • Field Details

  • Method Details

    • type

      ResolvedType type()
      Return type of vector values

    • size

      int size()
      Return size of vector

    • isNull

      boolean isNull(int row)
      Return if value at provided row is null

    • getString

      default UTF8String getString(int row)
      Get string at provided row.

    • getDateTime

      default EpochDateTime getDateTime(int row)
      Get date time at provided row

    • getDateTimeOffset

      default EpochDateTimeOffset getDateTimeOffset(int row)
      Get date time offset at provided row

    • getBoolean

      default boolean getBoolean(int row)
      Get boolean value for provided row

    • getInt

      default int getInt(int row)
      Get int value for provided row

    • getLong

      default long getLong(int row)
      Get long value for provided row

    • getDecimal

      default Decimal getDecimal(int row)
      Get decimal value for provided row

    • getFloat

      default float getFloat(int row)
      Get float value for provided row

    • getDouble

      default double getDouble(int row)
      Get double value for provided row

    • getAny

      default Object getAny(int row)
      Return value of provided row. NOTE! This method must not be used when checking if value is null. Use isNull(int).

    • getObject

      default ObjectVector getObject(int row)
      Return object for provided row

    • getArray

      default ValueVector getArray(int row)
      Return array for provided row

    • getTable

      default TupleVector getTable(int row)
      Return table for provided row

    • valueAsObject

      default Object valueAsObject(int row)
      Return value as object include null value. Note! This method differs from getAny(int) in that sense that this method converts the actual value to a boxed type and getAny(int) is the real accessor for the vectors actual type.

    • valueAsString

      default String valueAsString(int row)
      Return value as Java string for provided row

    • getPredicateBoolean

      default boolean getPredicateBoolean(int row)
      Get predicate boolean, ie. null is false
