Class ExpandableParameterSet

java.lang.Object
  de.jstacs.parameters.ParameterSet
      de.jstacs.parameters.ExpandableParameterSet

All Implemented Interfaces:

GalaxyConvertible, Storable, Cloneable

Direct Known Subclasses:

AbstractPerformanceMeasureParameterSet, AlphabetContainerParameterSet.SectionDefinedAlphabetParameterSet, ArrayParameterSet

public class ExpandableParameterSet
extends ParameterSet

A class for a ParameterSet that can be expanded by additional Parameters at runtime. The Parameters are all of type ParameterSetContainer. The contents of these Parameters are provided by a ParameterSet-template, which is cloned each time addParameterToSet() is called and set as value of a ParameterSetContainer that is added to the Parameters of the ExpandableParameterSet. Already added Parameters can also be removed from the set using removeParameterFromSet().

Constructor Detail

ExpandableParameterSet

public ExpandableParameterSet(ParameterSet template,

Creates a new ExpandableParameterSet from a Class that can be instantiated using this ExpandableParameterSet and templates for the ParameterSet in each element of the array, the name and the comment that are displayed for the ParameterSetContainers enclosing the ParameterSets.

Parameters:

template - the template of the ParameterSet

nameTemplate - the name-template

commentTemplate - the comment-template

Throws:

CloneNotSupportedException - if the template could not be cloned

ExpandableParameterSet

public ExpandableParameterSet(ParameterSet template,
                              String nameTemplate,
                              String commentTemplate,
                              int initCount)
                       throws CloneNotSupportedException

Creates a new ExpandableParameterSet from a Class that can be instantiated using this ExpandableParameterSet and templates for the ParameterSet in each element of the array, the name and the comment that are displayed for the ParameterSetContainers enclosing the ParameterSets.

Parameters:

template - the template of the ParameterSet

nameTemplate - the name-template

commentTemplate - the comment-template

initCount - the number of initial copies of the template

Throws:

CloneNotSupportedException - if the template could not be cloned

ExpandableParameterSet

public ExpandableParameterSet(StringBuffer representation)
                       throws NonParsableException

The standard constructor for the interface Storable. Creates a new ExpandableParameterSet from its XML representation.

Parameters:

representation - the XML represenation as StringBuffer

Throws:

NonParsableException - if the StringBuffer representation could not be parsed

ExpandableParameterSet

public ExpandableParameterSet(ParameterSet[] templateAndContent,
                              String nameTemplate,
                              String commentTemplate)

Creates a new ExpandableParameterSet from a ParameterSet -array. The first element of this array is taken as a template for further calls of addParameterToSet().

Parameters:

templateAndContent - the content (and template)

nameTemplate - the name-template

commentTemplate - the comment-template

Method Detail

clone

public ExpandableParameterSet clone()
                             throws CloneNotSupportedException

Description copied from class: ParameterSet

Creates a full clone (deep copy) of this ParameterSet. As a convenience-method the user can use fillWithStandardFieldsForClone(ParameterSet) on a newly created instance of a subclass of ParameterSet to obtain a clone/copy of all standard member variables (those already defined in ParameterSet) in the passed ParameterSet. Using this method, the cloning process becomes merely three-step:

• Create a new instance of your subclass of ParameterSet, most likely with an empty constructor or the one taking just the instance class.
• Call this.fillWithStandardFieldsForClone on this instance.
• Return the instance.

This method fulfills the conventions of Object's method Object.clone().

Overrides:

clone in class ParameterSet

Returns:

a deep clone/copy of this ParameterSet

Throws:

CloneNotSupportedException

addParameterToSet

public void addParameterToSet()
                       throws CloneNotSupportedException

Adds a new ParameterSetContainer containing a clone of the ParameterSet-template to the set of Parameters.

Throws:

CloneNotSupportedException - if the template could not be cloned

replaceContentWith

public boolean replaceContentWith(ParameterSet[] paramSetArray)

First removes all previous added ParameterSetContainers and afterwards adds all given ParameterSets (in the given order) enclosed in new ParameterSetContainers.

Parameters:

paramSetArray - the ParameterSets to be set

Returns:

true, if all given ParameterSets are of the same class as the defined template-ParameterSet of this ExpandableParameterSet, false otherwise (In this case, neither the previous added ParameterSetContainers are removed nor is any given ParameterSet added. Hence the ExpandableParameterSet stays unchanged.)

parameterRemovable

public boolean parameterRemovable()

Returns true if there is still a Parameter that can be removed from the set.

Returns:

true if a Parameter can be removed from the set

removeParameterFromSet

public void removeParameterFromSet()

Removes the last Parameter from set.

toXML

public StringBuffer toXML()

Description copied from interface: Storable

This method returns an XML representation as StringBuffer of an instance of the implementing class.

Specified by:

toXML in interface Storable

Overrides:

toXML in class ParameterSet

Returns:

the XML representation

fromXML

protected void fromXML(StringBuffer representation)
                throws NonParsableException

Description copied from class: ParameterSet

Parses the instance fields of a ParameterSet from the XML representation as returned by ParameterSet.toXML().

Overrides:

fromXML in class ParameterSet

Parameters:

representation - the XML representation as StringBuffer

Throws:

NonParsableException - if the XML code could not be parsed

              throws Exception

namePrefix - the prefix of the variable name used in Galaxy

configPrefix - the prefix for conditionals
