IlvDataTile (Rogue Wave JViews 9.2 API)

java.lang.Object
- ilog.views.chart.data.lod.IlvDataTile

```
public class IlvDataTile
extends Object
```
A data tile represents an elementary storage place for data loaded on-demand. Each IlvDataTile instance is created and controlled by an IlvDataTileController object. A tile is described by an interval along the x-axis, as well as an integer identifier computed according to the tile origin of its associated controller.

Since:

JViews 5.0

- Field Detail
  - EMPTY
```
public static final int EMPTY
```
    The status of an empty tile (neither loaded nor cached). This status corresponds to new tiles.

    getStatus(), Constant Field Values
  - LOCKED
```
public static final int LOCKED
```
    The status of a locked tile. A tile is locked when one more locks have been placed on it. The data in a locked tile is available.
    
    See Also:
    
    getStatus(), Constant Field Values
  - CACHED
```
public static final int CACHED
```
    The status of a cached tile. A cached tile is a tile which has no locks on it but which has its data present in memory (loaded earlier).

  - getController
```
public final IlvDataTileController getController()
```
    Returns the controller of the tile.
  - getindex
```
public final int getindex()
```
    Returns the ID of the tile. Each tile is associated with a unique integer identifier, determined according to the tile origin and tile length of the controller.
    
    Since:
    
    JViews 8.1
  - getIndex
```
public final Integer getIndex()
```
    Returns the ID of the tile. Each tile is associated with a unique integer identifier, determined according to the tile origin and tile length of the controller.
  - getRange
```
public final IlvDataInterval getRange()
```
    Returns the interval covered by the tile.
  - getStatus
```
public final int getStatus()
```
    Returns the status of the tile.

    EMPTY, CACHED, LOCKED
  - isLocked
```
public final boolean isLocked()
```
    Indicates whether the tile is locked.

  - isLocked
```
public final boolean isLocked(Object lock)
```
    Indicates whether the tile is locked by the specified object.
  - lock
```
public void lock(Object lock)
```
    Locks the tile.
    
    Parameters:
    
    lock - The object requesting a lock on the tile.
  - unlock
```
public boolean unlock(Object lock)
```
    Removes the specified lock from the tile. The tile is added to the cache by the controller if it is not locked by any other object.
    
    Parameters:
    
    lock - The considered lock.
    
    Returns:
    
    A boolean value indicating whether the tile is free from any lock.
  - getLocks
```
public Iterator getLocks()
```
    Returns an iterator over the objects that have locked the tile.
    
    Returns:
    
    An iterator over an unmodifiable version of the set of locks internally stored by the tile.
  - isLoadComplete
```
public final boolean isLoadComplete()
```
    Indicates whether the tile loading has been completed.
    
    See Also:
    
    loadComplete()
  - loadComplete
```
public void loadComplete()
```
    Notifies the tile that its loading is completed. This method should be called by the tile loader when the loading is performed.
    
    See Also:
    
    isLoadComplete(), IlvDataTileLoader.load(ilog.views.chart.data.lod.IlvDataTile)
  - notifyLoadError
```
public void notifyLoadError(Throwable errorReason)
```
    Notifies the tile that an error occurred during loading. This method notifies all listeners installed on the controller that manages this tile.
    
    Parameters:
    
    errorReason - The reason of the error.

    DataTileEvent.ERROR
  - setData
```
public void setData(IlvDoublePoints dataPts)
```
    Fills the tile with the specified data. This method should be used by the tile loaders to fill the tile with the loaded data.
    
    Parameters:
    
    dataPts - The new data for the tile. Data previously stored are replaced by this method.
  - hashCode
```
public int hashCode()
```
    Returns the hash code of the tile.
