Method Summary

Modifier and Type	Method	Description
`boolean`	`evaluate()`	Tries to evaluate the kappa term, if the evaluation is successful then the next call of value returns the evaluated value.
`java.util.Set<KappaTerm>`	`getSubTerms()`	Processes all the sub-terms
`int`	`greaterEqualThan()`
`java.lang.String`	`toString()`
`int`	`value()`	The neutral element is zero, that means if the sum contains no elements this method returns zero

    Description copied from interface: KappaTerm
    
    Tries to evaluate the kappa term, if the evaluation is successful then the next call of value returns the evaluated value.
    
    Specified by:
    
    evaluate in interface KappaTerm
    
    Returns:
    
    True if the evaluation is sucessful, false otherwise
  - value
```
public int value()
```
    The neutral element is zero, that means if the sum contains no elements this method returns zero
    
    Specified by:
    
    value in interface KappaTerm
    
    Returns:
    
    The value of this kappa term or -1 if the kappa-term's evaluate() method returns false.
  - greaterEqualThan
```
public int greaterEqualThan()
```
    Specified by:
    
    greaterEqualThan in interface KappaTerm
    
    Returns:
    
    The minimum value of this kappa term, such that the caller knows the kappa term is greater or equal the returned value.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
  - getSubTerms
```
public java.util.Set<KappaTerm> getSubTerms()
```
    Description copied from interface: KappaTerm
    
    Processes all the sub-terms
    
    Specified by:
    
    getSubTerms in interface KappaTerm
    
    Returns:
    
    A set containing all the sub-terms of the kappa term
