NumberFct

public NumberFct(Project p,
         SimpleAttDesc d,
         java.lang.String n)

Method Detail

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.

setDistanceFct

public void setDistanceFct(DistanceConfig df)

Sets the mode of this function to mode

Parameters:

df - the new mode of this function

getDistanceFct

public DistanceConfig getDistanceFct()

Returns the mode of this function

Returns:

the mode of this function

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
