  • Method Details

    • getComponentType

      public Class<?> getComponentType()
      Specified by:
      getComponentType in interface ColumnSource<Integer>
      Overrides:
      getComponentType in class AbstractColumnSource<Integer>
    • getInt

      public int getInt(long rowKey)
      Description copied from interface: ElementSource
      Get the value at the rowKey as an int. RowKeys that are not present are undefined.
      Specified by:
      getInt in interface ElementSource<Integer>
      Parameters:
      rowKey - the location in key space to get the value from.
      Returns:
      the int at the rowKey, null values are represented by QueryConstants.NULL_INT
    • getPrevInt

      public int getPrevInt(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey as an int. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.
      Specified by:
      getPrevInt in interface ElementSource<Integer>
      Parameters:
      rowKey - the location in key space to get the previous value from.
      Returns:
      the previous int at the rowKey, null values are represented by QueryConstants.NULL_INT
    • isImmutable

      public boolean isImmutable()
      Description copied from interface: ColumnSource
      Determine if this column source is immutable, meaning that the values at a given row key never change.
      Specified by:
      isImmutable in interface ColumnSource<Integer>
      Specified by:
      isImmutable in interface MutableColumnSource<Integer>
      Returns:
      true if the values at a given row key of the column source never change, false otherwise
    • isStateless

      public boolean isStateless()
      Description copied from interface: ColumnSource
      Most column sources will return the same value for a given row without respect to the order that the rows are read. Those columns sources are considered "stateless" and should return true. Some column sources, however may be dependent on evaluation order. For example, a formula that updates a Map must be evaluated from the first row to the last row. A column source that has the potential to depend on the order of evaluation must return false.
      Specified by:
      isStateless in interface ColumnSource<Integer>
      Returns:
      true if this is a stateless column source
