Field Detail

offset

protected int[] offset

This array is used to find the start indices of the conditional distributions.

Constructor Detail

InhConstraint

public InhConstraint(int[] pos,
                     int[] alphabetLength)

Parameters:

pos - the positions

alphabetLength - the length of each alphabet (not only the used positions)

InhConstraint

public InhConstraint(StringBuffer xml)
              throws NonParsableException

The constructor for saved objects.

Parameters:

xml - the representation

Throws:

NonParsableException - if the StringBuffer could not be parsed.

Method Detail

extractAdditionalInfo

protected void extractAdditionalInfo(StringBuffer xml)
                              throws NonParsableException

Description copied from class: Constraint

This method parses additional information from the StringBuffer that are not parsed in the base class.

Specified by:

extractAdditionalInfo in class Constraint

Parameters:

xml - the StringBuffer to parse

Throws:

NonParsableException - if something with the parsing went wrong

clone

public InhConstraint clone()
                    throws CloneNotSupportedException

Overrides:

clone in class Constraint

Throws:

CloneNotSupportedException

satisfiesSpecificConstraint

public int satisfiesSpecificConstraint(Sequence s,
                                       int start)

Description copied from class: Constraint

This method returns the index of the specific constraint that is fullfilled by the sequence beginning at start.

Specified by:

satisfiesSpecificConstraint in class Constraint

Parameters:

s - the sequence

start - the start position

Returns:

the index of the fulfilled, specific constraint

appendAdditionalInfo

protected void appendAdditionalInfo(StringBuffer xml)

Description copied from class: Constraint

This method appends additional information that are not stored in the base class to the StringBuffer.

Specified by:

appendAdditionalInfo in class Constraint

Parameters:

xml - the StringBuffer that is used for appending additional information
