Attribute

All Known Implementing Classes:

RealRep, TernaryRep
```
public interface Attribute
```
This interface has to be implemented for all attributes representation. By now, there are 3 implementations. Each one is a diferent attribute representation: - Real Representation - Integer Representation - Ternary Representation

Since:

JDK1.2

Version:

- Method Detail
  - setAllele
```
void setAllele(double lowerValue,
               double UpperValue)
```
    In case of being a character attribute, the char value is set as a double in the lowerValue parameter)
    
    Parameters:
    
    lowerValue - lower value of the allele.
    
    UpperValue - upper value of the allele.
  - setAllele
```
void setAllele(Attribute at)
```
    Sets an Allele (attribute) with the attribute given as parameter.
    
    Parameters:
    
    at - Attribute given.
  - getLowerAllele
```
double getLowerAllele()
```
    It returns the lower allele. If is a ternary representation, it returns the character of the position as a double
    
    Returns:
    
    the lower allele.
  - getUpperAllele
```
double getUpperAllele()
```
    It returns the upper allele. If is a ternary representation, it returns the character of the position as a double
    
    Returns:
    
    the upper allele.
  - getGenerality
```
double getGenerality()
```
    Returns the generality of the attribute. In ternary representation a 1 is returned if the symbol is a don't care, and in other representations the diference of the intervals is returned
    
    Returns:
    
    the generality of the attribute
  - verifyInterval
```
void verifyInterval()
```
    Does verify that the interval construction is correct
  - makeSpecify
```
void makeSpecify(double env)
```
    It applies the specify operator. The environmental value is needed
    
    Parameters:
    
    env - environmental value to be set.
  - mutate
```
void mutate(double envState)
```
    The mutation is done from the environmental state. The position i is needed for integer representation to know the bounds of the intervals
    
    Parameters:
    
    envState - environmental state needed for the mutation operator.
  - match
```
boolean match(double env)
```
    It checks if the position of the classifier matches with the value in the environment
    
    Parameters:
    
    env - environmental value to be checked.
    
    Returns:
    
    True if the classifier's position matches the environmental value, false otherwise.
  - equals
```
boolean equals(Attribute at)
```
    It checks if two attributes are equal
    
    Parameters:
    
    at - attribute to be checked
    
    Returns:
    
    True if both attributes are equal, if not false
  - subsumes
```
boolean subsumes(Attribute at)
```
    It checks if that attribute of the representation of the classifier can subsume the attribute passed as a parameter
    
    Parameters:
    
    at - attribute to be checked
    
    Returns:
    
    True if the attribute can subsume the attribute passed as a parameter, if not false
  - isDontCareSymbol
```
double isDontCareSymbol()
```
    If it's a ternary representation it returns 1 if is # and 0 otherwise. In representations with intervals it returns the diference between them.
    
    Returns:
    
    1 if is # and 0 otherwise
  - isMoreGeneral
```
boolean isMoreGeneral(Attribute at)
```
    Returns if the current interval is more general than the interval given as a parameter
    
    Parameters:
    
    at - attribute given to check.
    
    Returns:
    
    True if the current interval is more general than the interval given, false otherwise.
  - print
```
void print()
```
    Prints the classifier representation
  - print
```
void print(java.io.PrintWriter fout)
```
    Prints the classifier representation on the PrintWriter object given.
    
    Parameters:
    
    fout - PrintWriter object given to write on.
  - printNotNorm
```
void printNotNorm(java.io.PrintWriter fout,
                  double lo)
```
    Prints the classifier representation not normalized on the PrintWriter object given.
    
    Parameters:
    
    fout - PrintWriter object given to write on.
    
    lo - lower value in the interval.
  - printNotNorm
```
void printNotNorm(java.io.PrintWriter fout,
                  double lo,
                  double up)
```
    Prints the classifier representation not normalized on the PrintWriter object given.
    
    Parameters:
    
    fout - PrintWriter object given to write on.
    
    lo - lower value in the interval.
    
    up - upper value in the interval.
