Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`close()`
`ReferenceSequence`	`getSequence(String contig)`	Retrieves the complete sequence described by this contig.
`SAMSequenceDictionary`	`getSequenceDictionary()`	Must return a sequence dictionary with at least the following fields completed for each sequence: name, length.
`ReferenceSequence`	`getSubsequenceAt(String contig, long start, long stop)`	Gets the subsequence of the contig in the range [start,stop]
`boolean`	`isIndexed()`
`protected SAMSequenceDictionary`	`loadSequenceDictionary()`
`ReferenceSequence`	`nextSequence()`	Retrieves the next whole sequences from the file.
`void`	`reset()`	Resets the ReferenceSequenceFile so that the next call to nextSequence() will return the first sequence in the file.
