Constructor Detail

### UniformPositionPrior

    public UniformPositionPrior()

  This empty constructor creates an instance with motif length -1.

### UniformPositionPrior

    public UniformPositionPrior(StringBuffer xml)
                         throws NonParsableException

  The standard constructor for the interface `Storable`. Creates a new `UniformPositionPrior` out of its XML representation.

  Parameters:
    `xml` - the XML representation as `StringBuffer`
  Throws:
    `NonParsableException` - if the `StringBuffer` can not be parsed

Method Detail

### getLogPriorForPositions

    public double getLogPriorForPositions(int seqLength,
                                          int... starts)
                                   throws IllegalArgumentException

  Description copied from class: `PositionPrior`
  The logarithmic value of the prior for specified start positions of the part motifs.

  Specified by:
    `getLogPriorForPositions` in class `PositionPrior`
  Parameters:
    `seqLength` - the length of the sequence
    `starts` - the start positions of the part motifs
  Returns:
    the value of the prior for given start positions
  Throws:
    `IllegalArgumentException` - if something went wrong, e.g. the motif length is not set.

### getLength

    public final int getLength()

  Description copied from class: `PositionPrior`
  Returns the length that is supported by this prior. If all lengths greater than the minimal length are supported, this method returns 0.

  Specified by:
    `getLength` in class `PositionPrior`
  Returns:
    the length that is supported or 0 for all lengths

### getInstanceName

    public String getInstanceName()

  Description copied from class: `PositionPrior`
  Returns the instance name.

  Specified by:
    `getInstanceName` in class `PositionPrior`
  Returns:
    the instance name

### getAdditionalInformation

    protected StringBuffer getAdditionalInformation()

  Description copied from class: `PositionPrior`
  This method returns a `StringBuffer` containing additional information for the XML representation.

  Specified by:
    `getAdditionalInformation` in class `PositionPrior`
  Returns:
    a `StringBuffer` containing additional information for the XML representation

### extractAdditionalInformation

    protected void extractAdditionalInformation(StringBuffer xml)

  Description copied from class: `PositionPrior`
  This method extracts additional information from a `StringBuffer`.

  Specified by:
    `extractAdditionalInformation` in class `PositionPrior`
  Parameters:
    `xml` - the `StringBuffer` containing the additional information of the XML representation
