template<class T >

bool opencog::foreach_atom_pair ( const std::vector< Handle > &  va, const std::vector< Handle > &  vb, bool(T::*)(const Handle &, const Handle &)  cb, T *  data  )

inline

Zip together two lists of atoms, calling a function on it ziplist.

Invoke the callback on each pair of corresponding atoms in the vectors va and vb. This iterator is typically useful for making comparisons between atoms.

Returns true if all calls return true, return false otherwise.

References opencog::Handle::UNDEFINED.

template<typename T >

bool opencog::foreach_binary_link ( const Handle &  h, Type  ltype, bool(T::*)(const Handle &)  cb, T *  data  )

inline

foreach_binary_link – follow an ordered, binary link.

Look at the incoming set of the specified atom. Find all links of type link_type, then follow this link to see where its going. Call the callback for each endpoint found.

The callback should return false to search for more matches, or return true to halt the search.

template<typename T >

bool opencog::foreach_link ( const Handle &  h, Type  ltype, int  from, int  to, bool(T::*)(const Handle &)  cb, T *  data  )

inline

foreach_link – follow an ordered N-ary link.

Look at the incoming set of the specified atom. Find all links of type link_type. Check to make sure that the input handle "h" occupies position "from" in the link. If it does, then invoke the callback, passing the handle in position "to" to the callback. The callback is called for each endpoint found.

The callback should return false to search for more matches, or return true to halt the search.

HandleSeq opencog::get_predicates	(	const Handle &	target,
		Type	predicateType = PREDICATE_NODE,
		bool	subClasses = true
	)

Returns a list of all the EvaluationLinks with Predicates of the given type that the atom specified by 'target' participates in. (C++ implementation of cog-get-pred)

For example, given existence of the following:

EvaluationLink PredicateNode "IsA" ListLink ConceptNode "dog" ConceptNode "mammal"

EvaluationLink PredicateNode "IsA" ListLink ConceptNode "dog" ConceptNode "vertebrate"

EvaluationLink PredicateNode "eats" ListLink ConceptNode "dog" ConceptNode "meat"

and, given a get_predicates target of:

ConceptNode "dog"

and predicateType PREDICATE_NODE (or "PredicateNode"), then get_predicates returns evaluation links for:

dog IsA mammal
dog IsA vertebrate
dog eats meat

Parameters

target	Search for predicates that target.
predicateType	Search only for predicates of this type.
subClasses	Follow subtypes of linkType too.

HandleSeq opencog::get_predicates_for	(	const Handle &	target,
		const Handle &	predicate
	)

Returns a list of all the EvaluationLinks with the specified predicate that the atom specified by 'target' participates in.

For example, given the following:

EvaluationLink
   PredicateNode "IsA"
   ListLink
      ConceptNode "dog"
      ConceptNode "mammal"

EvaluationLink
   PredicateNode "IsA"
   ListLink
      ConceptNode "dog"
      ConceptNode "vertebrate"

EvaluationLink
   PredicateNode "eats"
   ListLink
      ConceptNode "dog"
      ConceptNode "meat"

then, given a target of:

ConceptNode "dog"

and predicate:

PredicateNode "IsA"

then get_predicates_for returns a list of all of the EvaluationLinks in which the dog has the "IsA" predicate, but not the one for "eats". So:

dog IsA mammal 
dog IsA vertebrate

but NOT:

dog eats meat

Parameters

target	Search for predicates that target.
predicateType	Search only for predicates of this type.
subClasses	Follow subtypes of linkType too.

Given a Handle remove it and all its descendants (outgoings of outgoings, etc). Atoms with incomings will not be removed. In case not all atoms have been removed it return false, true otherwise.

Parameters

as	The AtomSpace to the remove the atoms from
h	The handle to remove (and its descendants)

Returns

true if all atoms (h and its descendants) have been removed, false otherwise

Example: remove_hypergraph(as, h) with h = InheritanceLink ConceptNode "A" ConceptNode "B"

will remove the InheritanceLink, ConceptNode "A" and ConceptNode "B".
