Constructor Detail

FSDAGMParameterSet

public FSDAGMParameterSet(StringBuffer s)
                   throws NonParsableException

The constructor for the Storable interface.

Parameters:

s - the StringBuffer

Throws:

NonParsableException - if the StringBuffer is not parsable

FSDAGMParameterSet

public FSDAGMParameterSet(Class<? extends FSDAGModel> clazz)

This is the constructor that creates an empty parameter set.

Parameters:

clazz - the class of the object that will be created with this parameter set

FSDAGModel, FSDAGModelForGibbsSampling

FSDAGMParameterSet

public FSDAGMParameterSet(Class<? extends FSDAGModel> clazz,
                          AlphabetContainer alphabet,
                          int length,
                          double ess,
                          String description,
                          String graph)
                   throws Exception

This is the constructor that creates a filled parameter set.

Parameters:

clazz - the class of the object that will be created with this parameter set

alphabet - the alphabet container that is used in the model

length - the length of the model (has to be positive)

ess - the equivalent sample size (has to be positive)

description - a short description of the model (used for a better handling of the object by the user)

graph - the graph description string, encodes in XML-like manner the parents of each node "<parents node=i>j,k,l</parents>"

Throws:

Exception - if something went wrong

See Also:

encode(int[][])

Method Detail

loadParameters

protected void loadParameters()
                       throws Exception

Description copied from class: ParameterSet

Loads the parameters for this ParameterSet. This is in most cases done by simply creating a new ArrayList<Parameter> for the field parameters/code> and filling it with instances of subclasses of Parameter

Overrides:

loadParameters in class DGMParameterSet

Throws:

Exception - an Exception is thrown if the parameters could not be loaded

See Also:

ParameterSet.parameters, Parameter

getInstanceComment

public String getInstanceComment()

Description copied from class: ParameterSet

Returns a comment (a textual description) of the class that can be constructed using this ParameterSet.

Specified by:

getInstanceComment in class ParameterSet

Returns:

the comment

encode

public static String encode(int[][] graph)

This method can be used to encode adjacency list to a graph description string.

Parameters:

graph - graph[i] contains the parents of node i

Returns:

the graph description string
