Constructor Detail

MappedDiscreteSequence

protected MappedDiscreteSequence(AlphabetContainer originalAlphabetContainer,
                      SequenceAnnotation[] seqAn,
                      DiscreteAlphabetMapping... transformation)
                          throws WrongAlphabetException

This method allows to create an empty MappedDiscreteSequence. That is a MappedDiscreteSequence that contains no original Sequence.

Parameters:

originalAlphabetContainer - the original AlphabetContainer

seqAn - the SequenceAnnotations for the MappedDiscreteSequence

transformation - the DiscreteAlphabetMapping defining the mapping

Throws:

WrongAlphabetException - if the mapped AlphabetContainer is not discrete (should never happen)

MappedDiscreteSequence

public MappedDiscreteSequence(SimpleDiscreteSequence original,
                      DiscreteAlphabetMapping... transformation)
                       throws WrongAlphabetException

This method allows to create a MappedDiscreteSequence from a given Sequence and some given DiscreteAlphabetMappings.

Parameters:

original - the original Sequence

transformation - the DiscreteAlphabetMapping defining the mapping

Throws:

WrongAlphabetException - if the mapped AlphabetContainer is not discrete (should never happen)

Method Detail

getNewAlphabetContainer

public static final AlphabetContainer getNewAlphabetContainer(AlphabetContainer original,
                                        DiscreteAlphabetMapping... transformation)

This method allows to create a new AlphabetContainer given an old AlphabetContainer and some DiscreteAlphabetMappings.

Parameters:

original - the original AlphabetContainer

transformation - the DiscreteAlphabetMappings defining the mapping

Returns:

a new AlphabetContainer

discreteVal

public int discreteVal(int pos)

Description copied from class: Sequence

Returns the discrete value at position pos of the Sequence.

Specified by:

discreteVal in class Sequence<int[]>

Parameters:

pos - the position of the Sequence

Returns:

the discrete value at position pos of the Sequence

flatCloneWithoutAnnotation

protected MappedDiscreteSequence 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<int[]>

Returns:

the cloned Sequence without annotation

getLength

public int getLength()

Description copied from class: Sequence

Returns the length of the Sequence.

Specified by:

getLength in class Sequence<int[]>

Returns:

the length of the Sequence

getLogNumberOfPossibleOriginalSequences

public double getLogNumberOfPossibleOriginalSequences()

This method returns the logarithm of the number of original Sequences that yield the same mapped Sequence.

Returns:

the logarithm of the number of original Sequences that yield the same mapped Sequence

getLogNumberOfPossibleOriginalSequences

public double getLogNumberOfPossibleOriginalSequences(int start,
                                             int end)

This method returns the logarithm of the number of original Sequences that yield the same mapped Sequence.

Parameters:

start - the start position (inclusive)

end - the end position (exclusive)

Returns:

the logarithm of the number of original Sequences that yield the same mapped Sequence

getEmptyContainer

public final int[] getEmptyContainer()

Description copied from class: Sequence

The method returns a container that can be used for accessing the symbols for each position. This is especially of interest for multidimensional sequences.

Overrides:

getEmptyContainer in class SimpleDiscreteSequence

Returns:

a container that can be used for accessing the symbols for each position

Sequence.fillContainer(Object, int), Sequence.isMultiDimensional()

fillContainer

public final void fillContainer(int[] container,
                 int pos)

Description copied from class: Sequence

The method fills the content of a specific position in to the container. This is especially of interest for multidimensional sequences.

Overrides:

fillContainer in class SimpleDiscreteSequence

Parameters:

container - the container which is used for filling the content.

pos - the position
