    intSize, intSize, size

  • Method Details

    • getName

      String getName()

    • getType

      Class getType()
      Returns:
      the type of object contained within this column.

    • getComponentType

      Class getComponentType()
      Get the array component type, or the type itself. For basic types, this is just the type. For example, if you have a column of java.lang.String, this also returns java.lang.String. For array types (java Arrays), or DbArray (which would be returned by getType), you get the type that is contained within the array. For example, if a single row in this column contains a DbDoubleArray, getComponentType returns double.
      Returns:
      if type is an array, the type of object within the array. Otherwise type itself.

    • getDirect

      default Object getDirect()
      Get the contents of this data column in array form. Note that this will return an array of the appropriate primitive type for columns of non-Boolean primitive types.
      Returns:
      An appropriately-typed array containing the full contents of this data column

    • getDirect

      default Object getDirect​(long startIndexInclusive, long endIndexExclusive)
      Get the contents of a range of this data column in array form. See getDirect() for an explanation of return types. Note that it's required that endIndexExclusive - startIndexInclusive < Integer.MAX_VALUE.
      Parameters:
      startIndexInclusive - The first position in the data column to include, inclusive
      endIndexExclusive - One more than the last position in the data column to include
      Returns:
      An appropriately-typed array containing the contents of the specified range of this data column

    • getDirect

      default Object getDirect​(long... indexes)

    • getDirect

    • get

      TYPE get​(long index)

      Returns:
      the value in the column at the row designated by the index

    • get

      TYPE[] get​(long startIndexInclusive, long endIndexExclusive)

      Parameters:
      startIndexInclusive - The first position in the data column to include, inclusive
      endIndexExclusive - One more than the last position in the data column to include
      Returns:
      Return the column's values for the specified row range
