This defines an index entry for an individual sequence within a set of indexed files.

Author:
  Matthew Pocock

Method Summary
`File` | `getFile()` The file to retrieve from.
`String` | `getID()` The ID of the sequence at this position in this file.
`int` | `getLength()` The entry can be slurped out of the file by grabbing length bytes from start.
`long` | `getStart()` Skipping this number of bytes through the file should put the file pointer to the first byte of the sequence.

Method Detail

### getFile

    File getFile()

  The file to retrieve from.

  Returns:
    the File containing this Sequence

### getStart

    long getStart()

  Skipping this number of bytes through the file should put the file pointer to the first byte of the sequence.

  Returns:
    the offset within the file

### getLength

    int getLength()

  The entry can be slurped out of the file by grabbing length bytes from start. If the length can't be read from a store then this method should return -1.

  Returns:
    the length in bytes of this indexed entry

### getID

    String getID()

  The ID of the sequence at this position in this file.

  Returns:
    the ID of the indexed Sequence
