Method Detail

getDataStore

DataStore getDataStore(File storeFile)
                       throws IOException

Get a pre-built data store associated with a file.

Parameters:

storeFile - the File to map in as a data store

Returns:

the DataStore made by mapping the file

Throws:

IOException - if the file could not be mapped

buildDataStore

DataStore buildDataStore(File storeFile,
                         SequenceDB seqDB,
                         Packing packing,
                         int wordLength,
                         int threshold)
                         throws IllegalAlphabetException,
                                IOException,
                                BioException

Build a new DataStore.

Parameters:

storeFile - the file to store the data store

seqDB - the SequenceDB to store in the data store

packing - the Packing used to bit-encode the sequences

wordLength - the number of symbols per word

threshold - the number of times a word must appear to be ignored

Throws:

IllegalAlphabetException - if the packing does not agree with the sequences

BioException - if there is a problem building the data store

IOException
