Constructor Detail

DateFct

public DateFct(Project prj,
               DateDesc desc,
               java.lang.String name)

Method Detail

calculateSimilarity

public Similarity calculateSimilarity(Attribute value1,
                                      Attribute value2)
                               throws java.lang.Exception

Description copied from interface: ISimFct

Computes the similarity of value1 and value2. Be aware that this function does not have to be symmetric. The specified values have to be of same type and must belong to the same description, else null is returned.

Specified by:

calculateSimilarity in interface ISimFct

Parameters:

value1 - the first value

value2 - the second value

Returns:

similarity of value1 and value2, invalid similarity if the values do not have the same type or do belong to different attribute descriptions

Throws:

java.lang.Exception

getDesc

public AttributeDesc getDesc()

Description copied from interface: ISimFct

Returns the description of the attributes which can be compared using this function

Specified by:

getDesc in interface ISimFct

Returns:

the description this function belongs to

getMultipleConfig

public MultipleConfig getMultipleConfig()

Specified by:

getMultipleConfig in interface ISimFct

getName

public java.lang.String getName()

Description copied from interface: ISimFct

Returns the name of this function

Specified by:

getName in interface ISimFct

Returns:

the name of this function

getProject

public Project getProject()

Specified by:

getProject in interface ISimFct

isSymmetric

public boolean isSymmetric()

Description copied from interface: ISimFct

Specifies whether this function is symmetric or asymmetric

Specified by:

isSymmetric in interface ISimFct

Returns:

true, if similarity function is symmetric, false otherwise

setMultipleConfig

public void setMultipleConfig(MultipleConfig mc)

Specified by:

setMultipleConfig in interface ISimFct

setName

public void setName(java.lang.String name)

Description copied from interface: ISimFct

Sets the name of this function to name

Specified by:

setName in interface ISimFct

Parameters:

name - the new name of this function

setSymmetric

public void setSymmetric(boolean symmetric)

Description copied from interface: ISimFct

Specifies whether this function is symmetric or not. If a function sim is symmetric, sim(q,c) = sim(c,q) should hold for all queries q and cases c this function is defined on. Else the function is asymmetric.

Specified by:

setSymmetric in interface ISimFct

Parameters:

symmetric - specifies whether this function is symmetric or not.

update

public void update(java.util.Observable o,
                   java.lang.Object arg)

Specified by:

update in interface java.util.Observer

clone

public void clone(AttributeDesc descNEW,
                  boolean active)

Description copied from interface: ISimFct

Creates a new function which is the same function as this but with a different description, namely descNEW. Assumption: this function fits the description of descNEW.

Specified by:

clone in interface ISimFct
