Class JoiningSequenceReader<C extends Compound>

java.lang.Object

org.biojava.nbio.core.sequence.storage.JoiningSequenceReader<C>

Type Parameters:

C - Tyoe of compound to hold

All Implemented Interfaces:

Iterable<C>, Accessioned, ProxySequenceReader<C>, Sequence<C>, SequenceReader<C>

public class JoiningSequenceReader<C extends Compound>
extends Object
implements ProxySequenceReader<C>

This reader actually proxies onto multiple types of sequence in order to allow a number of sequence objects to act as if they are one sequence. The code takes in any number of sequences, records the minimum and maximum bounds each sequence covers with respect to 1 position indexing and then binary searches these when a position is requested. Because of this 0 length Sequences are excluded during construction. Performance is not as good as if you are using a flat sequence however the speed of lookup is more than adaquate for most situations. Using the iterator gives the best performance as this does not rely on the binary search mechanism instead iterating through each sequence in turn.

Constructor Detail

JoiningSequenceReader

public JoiningSequenceReader(Sequence<C>... sequences)

Allows creation of the store from Vargs Sequence objects. CompoundSet defaults to the first element of the array (assuming there are elements available during construction otherwise we will throw an illegal state exception).

JoiningSequenceReader

public JoiningSequenceReader(List<Sequence<C>> sequences)

Allows creation of the store from List>. CompoundSet defaults to the first element of the List (assuming there are elements available during construction otherwise we will throw an illegal state exception).
