de.dfki.mycbr.core.casebase.Attribute

de.dfki.mycbr.core.casebase.Instance

All Implemented Interfaces:

IExplainable, java.util.Observer

public final class Instance
extends Attribute
implements java.util.Observer, IExplainable

Represents values occurring in query and or cases. Each attribute knows its description and therefore knows how similar it is to other attributes of the same description. Attributes for a fixed description are maintained by ranges (classes implementing interface Range).

Constructor Detail

Instance

public Instance(Concept concept,
        java.lang.String id)

Creates new value for the specified description. Be aware that this instance will not belong to the concept, if you call this constructor. Better call Concept.addInstance(String) to create an instance properly!

Parameters:

concept - description of this attribute

id - the name of this instance

Method Detail

setName

public void setName(java.lang.String n)

Parameters:

n - new name of this

getName

public java.lang.String getName()

Specified by:

getName in interface IExplainable

Returns:

the name of this

getConcept

public Concept getConcept()

Gets the description for this attribute to determine similarity functions or restrictions for the value of this attribute.

Returns:

the description of this attribute

getAttributes

public java.util.HashMap<AttributeDesc,Attribute> getAttributes()

Gets all the attribute values for this c.

Returns:

the list of attributes of this c

removeAttribute

public void removeAttribute(AttributeDesc desc)

Removes the given attribute.

Parameters:

desc - the attribute to be removed

addAttribute

public boolean addAttribute(java.lang.String n,
                   Attribute a)

Sets the value of the attribute specified by desc to att. First checks whether this c attribute has a direct attribute description that corresponds to the description of the given attribute. If not, checks whether this c attribute has a super class that has a direct attribute description that corresponds to the given att's description. In any of these cases the given att is added to this c's attributes. Otherwise does nothing. It is assumed that you set the values for c attributes that are contained within this c attribute via composition separately by first adding the values to the corresponding c attribute and then add this c attribute as an attribute here.

Parameters:

n - the name of the attribute description

a - the value to be added to this c attribute.

Returns:

true, if the attribute was successfully added, false otherwise.

addAttribute

public boolean addAttribute(java.lang.String n,
                   java.lang.Object value)
                     throws java.text.ParseException

Parameters:

n - the name of the attribute description

value - the value of the attribute to be added

Returns:

true, if the attribute has been successfully added

Throws:

java.text.ParseException - if the value does not fit the description

addAttribute

public boolean addAttribute(AttributeDesc desc,
                   java.lang.Object value)
                     throws java.text.ParseException

Parameters:

desc - the description of the attribute to be added

value - the value to be added

Returns:

true, if attribute has been added successfully, false otherwise

Throws:

java.text.ParseException - if the value does not fit the description

addAttribute

public boolean addAttribute(AttributeDesc desc,
                   Attribute a)

Parameters:

desc - the description of the attribute to be added

a - the attribute to be added

Returns:

true, if the attribute has been successfully added, false otherwise

getAttForDesc

public Attribute getAttForDesc(AttributeDesc attDesc)

Returns the attribute for the given description. Returns null, if there is no attribute for this description.

Parameters:

attDesc - the description for which the attribute should be returned

Returns:

the attribute corresponding to attDesc, null if there is none

getValueAsString

public java.lang.String getValueAsString()

Returns the string representation of this c attribute.

Specified by:

getValueAsString in class Attribute

Returns:

string representation of this c attribute

getExpType

Specified by:

getExpType in interface IExplainable

Returns:

type of explainable object.
