    • getComponentType

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

    • get

      public T get(long rowKey)
      Description copied from interface: ElementSource
      Get the value from the source. This may return boxed values for basic types. RowKeys that are not present are undefined.
      Specified by:
      get in interface ElementSource<T>
      Parameters:
      rowKey - the location in key space to get the value from.
      Returns:
      the value at the rowKey, potentially null.

    • getPrev

      public T getPrev(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey. Previous values are used during an UG update cycle to process changes in data. During normal operation previous values will be identical to current values. RowKeys that were not present are undefined.
      Specified by:
      getPrev in interface ElementSource<T>
      Parameters:
      rowKey - the location in key space to get the value from.
      Returns:
      the previous value at the rowKey, potentially null.

    • getBoolean

      public Boolean getBoolean(long rowKey)
      Description copied from interface: ElementSource
      Get the value at the rowKey as a Boolean. RowKeys that are not present are undefined.
      Specified by:
      getBoolean in interface ColumnSourceGetDefaults.ForObject<T>
      Specified by:
      getBoolean in interface ElementSource<T>
      Parameters:
      rowKey - the location in key space to get the value from.
      Returns:
      the boolean at the rowKey, potentially null.

    • getPrevBoolean

      public Boolean getPrevBoolean(long rowKey)
      Description copied from interface: ElementSource
      Get the previous value at the rowKey as a Boolean. See ElementSource.getPrev(long) for more details. RowKeys that were not present are undefined.
      Specified by:
      getPrevBoolean in interface ElementSource<T>
      Specified by:
      getPrevBoolean in interface MutableColumnSourceGetDefaults.ForObject<T>
      Parameters:
      rowKey - the location in key space to get the previous value from.
      Returns:
      the previous boolean at the rowKey, potentially null.

    • 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<T>
      Specified by:
      isImmutable in interface MutableColumnSource<T>
      Returns:
      true if the values at a given row key of the column source never change, false otherwise
