Class SingleCompoundSequenceReader<C extends Compound>

java.lang.Object

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

All Implemented Interfaces:

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

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

An implementation of the SequenceReader interface which for every call will return only 1 compound (given to it during construction; a String is also valid but will require a CompoundSet). The idea is to represent large runs of a single compound without the memory footprint of storing these compounds e.g. a run of 10KB of Ns in a DNASequence.

Method Detail

setCompoundSet

public void setCompoundSet(CompoundSet<C> compoundSet)

Unsupported

Specified by:

setCompoundSet in interface SequenceReader<C extends Compound>

getLength

public int getLength()

Returns the length given during construction

Specified by:

getLength in interface Sequence<C extends Compound>

getCompoundAt

public C getCompoundAt(int position)

Always returns the compound given at construction

Specified by:

getCompoundAt in interface Sequence<C extends Compound>

Parameters:

position - Biological index (1 to n)

Returns:

Compound at the specified position

getIndexOf

public int getIndexOf(C compound)

Returns 1 if the given compound is equal to the one given during construction; otherwise will return -1.

Specified by:

getIndexOf in interface Sequence<C extends Compound>

Parameters:

compound - Compounds to look for

Returns:

Index of the first position of the compound in the sequence (1 to n)

getLastIndexOf

public int getLastIndexOf(C compound)

Returns the length of the Sequence if the given compound was equal to the one given during construction. Otherwise returns -1

Delegates to SequenceMixin.toList(org.biojava.nbio.core.sequence.template.Sequence)

Specified by:

getSequenceAsString in interface Sequence<C extends Compound>

getAsList

public List<C> getAsList()

Delegates to SequenceMixin.toList(org.biojava.nbio.core.sequence.template.Sequence)

Specified by:
