    This function returns true if the image to be loaded needs a enhanced filter or doesn't. It depends on the format, number of bands, type of data and so on.
    
    Specified by:
    
    needEnhanced in interface RasterProvider
    
    Returns:
    The default value is false but each driver can change this value.
  - getInterval
```
public Interval getInterval()
```
    Gets the Interval of the store, that means the temporal interval where the store has valid data. In raster this method has sense in a mosaic. Therefore this has to be implemented by the provider.
    
    Returns:
    a time interval or null if there is not time support
  - getTimes
```
public Collection<?> getTimes()
```
    Gets all the possible values of time for which the store has data. In raster this method has sense in a mosaic. Therefore this has to be implemented by the provider.
    
    Returns:
    a collection of Time objects.
  - getTimes
```
public Collection<?> getTimes(Interval interval)
```
    Gets all the possible values of time for which the store has data and intersects with an interval. In raster this method has sense in a mosaic. Therefore this has to be implemented by the provider.
    
    Parameters:
    interval - the interval of time
    
    Returns:
    a collection of Time objects.
  - getGeoPointList
```
public GeoPointList getGeoPointList()
```
    Gets the list of geo points associated to this provider
    
    Specified by:
    
    getGeoPointList in interface RasterProvider
    
    Returns:
    the list of geo points
  - setGeoPointList
```
public void setGeoPointList(GeoPointList geoPointList)
```
    Sets the list of geo points associated to this provider
    
    Specified by:
    
    setGeoPointList in interface RasterProvider
  - getDefaultBandList
```
public BandList getDefaultBandList()
```
    Deprecated. This method should not be used. The store have a getDefaultBandList
    
    Returns:
    BandList
  - close
```
public void close()
```
    Description copied from interface: DataStoreProvider
    
    Request to close de source
    
    Specified by:
    
    close in interface RasterProvider
    
    Overrides:
    
    close in class AbstractCoverageStoreProvider
  - finalize
```
protected void finalize()
                 throws Throwable
```
    Overrides:
    
    finalize in class Object
    
    Throws:
    
    Throwable
