Constructor Detail

Gene

public Gene()

Default constructor

Gene

public Gene(Attribute a)

this constructor builds up a gene from the information of an attribute

Parameters:

a - the attribute

Gene

public Gene(Gene gen)

Copy constructor, performs a deep copy of the passed object

Parameters:

gen - the gene to be copied

Method Detail

getNegationBit

public int getNegationBit()

Obtains the status of the negation bit

Returns:

the status of the negation bit

getNumBits

public int getNumBits()

Obtains the number of bits (computed from the attribute associated)

Returns:

the number of bits (computed from the attribute associated)

getBit

public char getBit(int pos)

Get the bit indicated

Parameters:

pos - position of the bit to be retrieved

Returns:

the status of the bit

setNegation

public void setNegation(int isNeg)

Sets the negation bit of this gene

Parameters:

isNeg - The new negation status

setBit

public void setBit(int i,
                   char newBit)

Sets the bits status indicated by index and value

Parameters:

i - the index of the bit

newBit - the new status (0 or 1)

bin2nominal

public java.util.ArrayList<java.lang.Integer> bin2nominal()

This method converts from the status of the gene to a list of nominals values of the attribute which are currently covered

Returns:

the arraylist of currently covered nominal values

test

public boolean test(double value)

Test if the passed value (index of the nominal in the attribute) is covered by this gene

Parameters:

value - the index of the nominal value in the attribute list

Returns:

True if the value is covered by the gene, False otherwise

applydiffs

public void applydiffs(double value)

Transforms the current gene, so the attribute value is now covered by this gene

Parameters:

value - the nominal value to be covered
