Constructor Detail

FreqListPair

public FreqListPair()

Creates a new object, with fresh allocated memory

Method Detail

AddElement

public void AddElement(java.lang.String newElem1,
                       java.lang.String newElem2)

Adds a new pair, increasing its frequency if already exists, or creating a new pair if not

Parameters:

newElem1 - First element of the new pair

newElem2 - Second element of the new pair

mostCommon

public ValuesFreq mostCommon()

Returns the most frequent pair

Returns:

The pair with highest frequency

numElems

public int numElems()

Number of different pairs of this list

Returns:

Number of different pairs of this list

elementAt

public ValuesFreq elementAt(int i)

Returns the element at position indicated

Parameters:

i - Position of the element we want

Returns:

The element at position i

reset

public void reset()

Reset the iterator to the beginning of the list.

iterate

public boolean iterate()

Iterates to the next element in the list

Returns:

True if still there are more elements remaining, false if the end of the list has been reached.

getCurrent

public ValuesFreq getCurrent()

Obtains the element pointed currently by the iterator

Returns:

The current element

outOfBounds

public boolean outOfBounds()

Test if the iterator is out of the bounds of the list

Returns:

True if the iterator is beyond the limit, of false if there are still more elements

totalElems

public int totalElems()

The total number of elements stored, i.e. the sum of all the frequencies

Returns:

the total number of elements added to this list

elem1SumFreq

public int elem1SumFreq(java.lang.String val)

Sums the frequencies for the first elements which are equal to the provided one

Parameters:

val - the reference value

Returns:

the sum of frequencies of all pairs which have the first element equal to val

elem2SumFreq

public int elem2SumFreq(java.lang.String val)

Sums the frequencies for the second elements which are equal to the provided one

Parameters:

val - the reference value

Returns:

the sum of frequencies of all pairs which have the second element equal to val

getPairFreq

public int getPairFreq(java.lang.String e1,
                       java.lang.String e2)

Searches for the first pair which has its elements equals to the provided ones, and return it frequency

Parameters:

e1 - the first element of the pair

e2 - the second element of the pair

Returns:

the retrieved frequency of the pair

sumPairFreq

public int sumPairFreq(java.lang.String e1,
                       java.lang.String e2)

Searches for the all the pairs which have its elements equals to the provided ones, and return their cummulative frequency

Parameters:

e1 - the first element of the pair

e2 - the second element of the pair

Returns:

the sum of all frequencies
