Constructor and Description
FastaReader(java.io.File file, FastaHeaderParserInterface<S,C> headerParser, SequenceCreatorInterface<C> sequenceCreator) If you are going to use the FileProxyProteinSequenceCreator then you need to use this constructor because we need details about the location of the file.
FastaReader(java.io.InputStream is, FastaHeaderParserInterface<S,C> headerParser, SequenceCreatorInterface<C> sequenceCreator) If you are going to use FileProxyProteinSequenceCreator then do not use this constructor because we need details about local file offsets for quick reads.

Constructor Detail

FastaReader

public FastaReader(java.io.InputStream is,
           FastaHeaderParserInterface<S,C> headerParser,
           SequenceCreatorInterface<C> sequenceCreator)

If you are going to use FileProxyProteinSequenceCreator then do not use this constructor because we need details about local file offsets for quick reads. InputStreams does not give you the name of the stream to access quickly via file seek. A seek in an inputstream is forced to read all the data so you don't gain anything.

Parameters:

br -

headerParser -

sequenceCreator -

FastaReader

public FastaReader(java.io.File file,
           FastaHeaderParserInterface<S,C> headerParser,
           SequenceCreatorInterface<C> sequenceCreator)
            throws java.io.FileNotFoundException

If you are going to use the FileProxyProteinSequenceCreator then you need to use this constructor because we need details about the location of the file.

Parameters:

file -

headerParser -

sequenceCreator -

Throws:

java.io.FileNotFoundException - if the file does not exist, is a directory rather than a regular file, or for some other reason cannot be opened for reading.

java.lang.SecurityException - if a security manager exists and its checkRead method denies read access to the file.
