## de.jstacs.data
Class Sequence.SubSequence

    java.lang.Object
      de.jstacs.data.Sequence
          de.jstacs.data.sequences.RecursiveSequence
              de.jstacs.data.Sequence.SubSequence

All Implemented Interfaces:
  Comparable<Sequence>

Enclosing class:
  Sequence

    protected static class Sequence.SubSequence

extends RecursiveSequence

This class handles subsequences. `Sequence.SubSequence`s are often used to extract the `Sequence` of a sliding window on a long `Sequence`. The class is implemented in such a way that it avoids chains of `Sequence.SubSequence`s.

Fields inherited from class de.jstacs.data.Sequence
`alphabetCon, annotation, rc`

Constructor Summary
`Sequence.SubSequence(AlphabetContainer abc, Sequence seq, int start, int length)` This constructor should be used if one wants to create a `Sample` of `Sequence.SubSequence`s of defined length.
`Sequence.SubSequence(Sequence seq, int start, int length)` This is a very efficient way to create a `Sequence.SubSequence` of defined length for `Sequence`s with a simple `AlphabetContainer`.

Method Summary
`int` | `discreteVal(int pos)` Returns the discrete value at position `pos` of the `Sequence.CompositeSequence`.
`protected Sequence` | `flatCloneWithoutAnnotation()` Works in analogy to `Object.clone()`, but does not clone the annotation.
`protected int` | `getIndex(int pos)` Returns the index in the internal sequence.
`int` | `getLength()` Returns the length of the `Sequence.CompositeSequence`.
`Sequence` | `reverseComplement(int start, int end)` This method returns a new instance of `Sequence.CompositeSequence` containing a reverse part of the complementary current `Sequence.CompositeSequence`.

Constructor Detail

### Sequence.SubSequence

    public Sequence.SubSequence(AlphabetContainer abc,
                                Sequence seq,
                                int start,
                                int length)

  This constructor should be used if one wants to create a `Sample` of `Sequence.SubSequence`s of defined length. With this constructor you are enabled to create a `Sample` where every `Sequence` has the same `AlphabetContainer` instance.
  Internally it is checked that the `AlphabetContainer` matches with the one of the `Sequence.SubSequence`.

  Parameters:
    `abc` - the new `AlphabetContainer`
    `seq` - the original `Sequence`
    `start` - the index of the start position
    `length` - the length of the new sequence

### Sequence.SubSequence

    public Sequence.SubSequence(Sequence seq,
                                int start,
                                int length)

  This is a very efficient way to create a `Sequence.SubSequence` of defined length for `Sequence`s with a simple `AlphabetContainer`.

  Parameters:
    `seq` - the original `Sequence`
    `start` - the index of the start position
    `length` - the length of the new `Sequence`

Method Detail

### reverseComplement

    public Sequence reverseComplement(int start,
                                      int end)
                               throws OperationNotSupportedException

  Description copied from class: `Sequence`
  This method returns a new instance of `Sequence.CompositeSequence` containing a reverse part of the complementary current `Sequence.CompositeSequence`. For more details see the methods `Sequence.reverse()` and `Sequence.complement()`.

  Overrides:
    `reverseComplement` in class `Sequence`
  Parameters:
    `start` - the start position (inclusive) in the original `Sequence.CompositeSequence`
    `end` - the end position (exclusive) in the original `Sequence.CompositeSequence`
  Returns:
    the reverse complementary `Sequence.CompositeSequence` of the part
  Throws:
    `OperationNotSupportedException` - if the current `Sequence.CompositeSequence` is not discrete and simple ((not based on a `ComplementableDiscreteAlphabet`)
  See Also:
    `Sequence.reverse()`, `Sequence.complement()`, `ComplementableDiscreteAlphabet`

### getIndex

    protected final int getIndex(int pos)

  Description copied from class: `RecursiveSequence`
  Returns the index in the internal sequence.

  Specified by:
    `getIndex` in class `RecursiveSequence`
  Parameters:
    `pos` - the index in the external sequence
  Returns:
    the index in the internal sequence

### discreteVal

    public final int discreteVal(int pos)

  Description copied from class: `Sequence`
  Returns the discrete value at position `pos` of the `Sequence.CompositeSequence`.

  Overrides:
    `discreteVal` in class `RecursiveSequence`
  Parameters:
    `pos` - the position of the `Sequence.CompositeSequence`
  Returns:
    the discrete value at position `pos` of the `Sequence.CompositeSequence`

### getLength

    public int getLength()

  Description copied from class: `Sequence`
  Returns the length of the `Sequence.CompositeSequence`.

  Specified by:
    `getLength` in class `Sequence`
  Returns:
    the length of the `Sequence.CompositeSequence`

### flatCloneWithoutAnnotation

    protected Sequence flatCloneWithoutAnnotation()

  Description copied from class: `Sequence`
  Works in analogy to `Object.clone()`, but does not clone the annotation. This method is used in `Sequence.annotate(boolean, SequenceAnnotation...)`.

  Specified by:
    `flatCloneWithoutAnnotation` in class `Sequence`
  Returns:
    the cloned `Sequence.CompositeSequence` without annotation
