addArgument

public void addArgument(Term<?> arg)

Adds an argument to the atom's argument list

Specified by:

addArgument in interface Atom

Parameters:

arg - The next argument

getArguments

public java.util.List<? extends Term<?>> getArguments()

Specified by:

getArguments in interface Atom

Returns:

A list containing all the arguments of this specific atom

isComplete

public boolean isComplete()

setPredicate

public Atom.RETURN_SET_PREDICATE setPredicate(Predicate predicate)

Description copied from interface: Atom

Changes the predicate of the atom. Given an old Predicate po and a new predicate pn with their list of arguments types at(po) and at(pn) and the arguments of this Atom: arg(this) this method distinguishes between three cases: 1. The predicate only differ in the names, returning RSP_SUCCESS 2. The old predicates argument types is a sub-list of the new argument types then the method returns RSP_INCOMPLETE and the atoms isComplete() method returns false 3. The new predicates argument types is a sub-list of the old argument types then the method returns RSP_TRUNCATED and the arguments of this atom are truncated too and isComplete() returns true. 4. The old and new predicates' argument types differ then the list of arguments of the atom get cleared and isComplete() returns false.

Specified by:

setPredicate in interface Atom

Parameters:

predicate - some predicate

Returns:

Depends on the cases described above: 1. RSP_SUCCESS 2. RSP_INCOMPLETE 3. RSP_TRUNCATED 4. RSP_CLEARED

compareTo

Specified by:

compareTo in interface java.lang.Comparable<LdoArgument>
