Constructor Detail

Operator

public Operator()

Default Operator constructor. The operator type is NOT defined!

Operator

public Operator(String newType,
                float newParameter)

Constructs a new operator with specified property values.

Parameters:

newType - The new value for the property type.

newParameter - The new value for the property parameter.

Method Detail

getType

public String getType()

Returns the type of this operator.

Returns:

the type property

See Also:

setType(java.lang.String)

setType

public void setType(String newType)
             throws PropertyVetoException

Sets the operator type. If the new type requires a parameter, the default value is set.

Parameters:

newType - The new value for the property.

Throws:

PropertyVetoException - when the attempt to set the property is vetoed by a listener

See Also:

getType()

getParameter

public float getParameter()

Returns the parameter of this operator.

Returns:

the parameter property

See Also:

setParameter(float)

setParameter

public void setParameter(float param)
                  throws PropertyVetoException

Sets the parameter of this operator.

Parameters:

param - The new value for the property.

Throws:

PropertyVetoException - when the attempt to set the property is vetoed by a listener

See Also:

getParameter()

combine

public FuzzySet combine(FuzzySet fs1,
                        FuzzySet fs2)

Combines two fuzzy sets appropiated the operator type.

Parameters:

fs1 - The first fuzzy set as operand

fs2 - The second fuzzy set as operand

Returns:

The result of this fuzzy operation

isValidSNorm

public boolean isValidSNorm()

Indicates whether an operator fullfils the s-norm.

Returns:

true if this operator fullfils the s-norm, false otherwise.

isValidTNorm

public boolean isValidTNorm()

Indicates whether an operator fullfils the t-norm.

Returns:

true if this operator fullfils the t-norm, false otherwise.

addVetoableChangeListener

public void addVetoableChangeListener(VetoableChangeListener listener)

Adds a VetoableChangeListener to the listener list. The listener is registered for all properties.

Parameters:

listener - the VetoableChangeListener to be added

removeVetoableChangeListener

public void removeVetoableChangeListener(VetoableChangeListener listener)

Removes a VetoableChangeListener from the listener list. This removes a VetoableChangeListener that was registered for all properties.

Parameters:

listener - the VetoableChangeListener to be removed

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list. The listener is registered for all properties.

A PropertyChangeEvent will get fired in response to setting a bound property.

Parameters:

listener - the PropertyChangeListener to be added

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.

Parameters:

listener - the PropertyChangeListener to be removed

clone

public Object clone()

Overrides:

clone in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
