| ModuleSpec | | public class ModuleSpec implements Cloneable(Code) | | This generic class is used to handle values to be used by a module for each
tile and component. It uses attribute to determine which value to use. It
should be extended by each module needing this feature.
This class might be used for values that are only tile specific or
component specific but not both.
The attributes to use are defined by a hierarchy. The hierarchy is:
- Tile and component specific attribute
- Tile specific default attribute
- Component main default attribute
- Main default attribute

tiles to the 'SPEC_DEF' spec val type, for the specified number of
components and tiles.
Parameters:
nt - The number of tiles

tile or component indexes are separated by commas or a
dashes.
Example:
t0,3,4 means tiles with indexes 0, 3 and 4.
t2-4 means tiles with indexes 2,3 and 4.
It returns a boolean array skteching which tile or component are
concerned by the next parameters.
Parameters:
word - The word to parse.
Parameters:
