org.geotools.coverage.grid.GridCoverage2D.dispose()
Provides a hint that a coverage will no longer be accessed from a reference in user space. This method {@linkplain PlanarImage#dispose disposes} the {@linkplain #image} only if atleast one of the following conditions is true (otherwise this method do nothing):
- {@code force} is {@code true}, or
- The underlying {@linkplain #image} has no {@linkplain PlanarImage#getSinks sinks}other than the views (geophysics, display, etc.).
This safety check helps to prevent the disposal of an {@linkplain #image} that stillused in a JAI operation chain. It doesn't prevent the disposal in every cases however. When unsure about whatever a coverage is still in use or not, it is safer to not invoke this method and rely on the garbage collector instead. @see PlanarImage#dispose @since 2.4
