Method Detail

setMark

void setMark(int p,
             int mark)

Mark a given literal with a given mark.

Parameters:

p - the literal

mark - an integer used to mark the literal. The specific mark MARKLESS is used to denote that the literal is not marked. The marks are supposed to be positive in the most common cases.

setMark

void setMark(int p)

Mark a given literal.

Parameters:

p - a literal

getMark

int getMark(int p)

To get the mark for a given literal.

Parameters:

p - a literal

Returns:

the mark associated with that literal, or MARKLESS if the literal is not marked.

isMarked

boolean isMarked(int p)

To know if a given literal is marked, i.e. has a mark different from MARKLESS.

Parameters:

p - a literal

Returns:

true iif the literal is marked.

resetMark

void resetMark(int p)

Set the mark of a given literal to MARKLESS.

Parameters:

p - a literal

resetAllMarks

void resetAllMarks()

Set all the literal marks to MARKLESS

getMarkedLiterals

IVecInt getMarkedLiterals()

Returns the set of all marked literals.

Returns:

a set of literals whose mark is different from MARKLESS.

getMarkedLiterals

IVecInt getMarkedLiterals(int mark)

Returns that set of all the literals having a specific mark.

Parameters:

mark - a mark

Returns:

a set of literals whose mark is mark

getMarkedVariables

IVecInt getMarkedVariables()

Returns the set of all marked variables. A variable is marked iff at least one of its literal is marked.

Returns:

a set of variables whose mark is different from MARKLESS.

getMarkedVariables

IVecInt getMarkedVariables(int mark)

Returns the set of all variables having a specific mark. A variable is marked iff at least one of its literal is marked.

Parameters:

mark - a mark.

Returns:

a set of variables whose mark is mark.

getMarks

java.util.Set<java.lang.Integer> getMarks()

Returns:

a list of marks used to mark the literals.
