Direct Known Subclasses:

PairwiseStringAlignment

public class StringAlignment
extends Object

Class for the representation of an alignment of Strings. It contains the Strings that were aligned and expanded by gap-symbols, and the edit-costs according to the employed Costs instance.

Constructor Detail

StringAlignment

public StringAlignment(double cost,
                       String... strings)

This constructor creates an instance storing the aligned Strings and the costs of the alignment.

Parameters:

cost - the cost of the alignment

strings - the aligned and expanded Strings

Method Detail

getCost

public double getCost()

Returns the costs.

Returns:

the costs

getNumberOfAlignedSequences

public int getNumberOfAlignedSequences()

Returns the number of sequences in this alignment.

Returns:

the number of sequences in this alignment.

getAlignedString

public String getAlignedString(int index)

Returns the aligned String with index index.

Parameters:

index - the index of the String

Returns:

the aligned String with index index

toString

public String toString()

Overrides:

toString in class Object

toString

public String toString(int chunkSize,
                       int simplifyIdx,
                       List<String> annot)

This method returns a String representation of the alignment with a given chunk size. I.e. all aligned sequence will be split each chunkSize symbols.

Parameters:

chunkSize - the size of the chunks

simplifyIdx - if non-negative the alignment is given relative to the sequence with the corresponding index; i.e. match is represented by "." and mismatch by the corresponding symbol

annot - a list of annotations for the aligned Strings, can be null

Returns:

a String representation of the alignment

getLength

public int getLength()

This method return the length of the alignment.

Returns:

the length of the alignment
