applyRelevantFilters

public DataSource applyRelevantFilters(DataSource original)
                                throws IOException

Apply all the relevant data filters, taking care of layers.

If several filters can be applied, they will all be applied as a stack, even recursively if required. This means that if filter A applies to files with names of the form base.ext.a and filter B applies to files with names of the form base.ext.b, then providing base.ext.a.b.a will result in filter A being applied on top of filter B which itself is applied on top of another instance of filter A.

Parameters:

original - original data source

Returns:

fully filtered data source

Throws:

IOException - if some data stream cannot be filtered
