getTypeNames

public abstract String[] getTypeNames()

mergeHints

protected Query mergeHints(Query q)

Merges the wrapper hints with the query ones, making sure not to overwrite the query ones

Parameters:

q -

Returns:

setMultiScaleROIProvider

public void setMultiScaleROIProvider(MultiLevelROIProvider footprintProvider)

getGranuleFootprint

protected MultiLevelROI getGranuleFootprint(SimpleFeature sf)

Returns the footprint for the given granule. Mind, when applying insets we might have the case of the geometry being empty (negative buffer eroded it fully), in that case the granule must not be loaded

Parameters:

sf -

Returns:

drop

public abstract void drop()
                   throws IOException

Drop the underlying catalog, all the individual granule indexes.

This is usuallu done when deleting an ImageMosaic storre.

Throws:

IOException - in case something bad happens
