Method Detail

getInstance

InfoStructure getInstance(int type)
                          throws UnknownInfoStructureException

Returns a new InfoStructure instance according to the type specified as input parameter. This type has to be one of the valid types defined by this interface's public constants. After this method has been invoked, please remember to initialize the obtained instance by calling its fromStream method, and by setting the reference to the Dna instance this INFO_structure will belong to.

Parameters:

type - The type of the required instance

Returns:

InfoStructure A valid InfoStructure implementation of the given type type

Throws:

DnaDeserializationException

UnknownInfoStructureException

getInstance

InfoStructure getInstance(int type,
                          java.io.DataInputStream dis,
                          Dna dna)
                          throws UnknownInfoStructureException,
                                 DnaDeserializationException

Returns a new InfoStructure instance according to the type specified as input parameter. This type has to be one of the valid types defined by this interface's public constants.

Parameters:

type - The type of the required instance

dis - The input stream for reading the info structure in

dna - The current Dna instance

Returns:

InfoStructure The requested InfoStructure instance

Throws:

UnknownInfoStructureException - The provided type is not valid

DnaDeserializationException
