Module Tp5

A module for transforming a “Tuple predicate” with 5 arguments.

In qtil speak:

a “Function” (FnX) is a predicate with a bindingset[] on all of its arguments, and a result
a "TuplePredicate " (TpX) is a predicate with finite arguments and no result
a “Relation” (RelX) is a predicate with finite arguments and a finite result
a “Property” (PropX) is a predicate with a bindingset[] on all arguments no result

Essentially, a tuple predicate Tp<A, B, C> represents a finite set of tuples (a, b, c). This module accepts a tuple predicate (predicate p(A, B, C)) as an input, and offers functional programming features on top of it such as map and filter, as well as some relational algebra features such as projection and joins.

Example:

predicate livesIn(Person p, City c) { c = p.getCity() }
string describe(Person p, City c) { result = p.getName() + " lives in " + c.getName() }

// selects "Peter lives in New York", "Wanda lives in London", ...
select Tp2<Person, City, livesIn/2>::Map<string, describe/2>::find()

Predicates

contains	Checks if (a, b, c, …) is a member of the tuple set represented by this “tuple predicate.”
doCount	Count the number of tuples in this tuple set.
dropFifth	Drop the fifth column in the set of tuples that satisfy the given predicate, and get a new tuple set after that column has been dropped.
dropFirst	Drop the first column in the set of tuples that satisfy the given predicate, and get a new tuple set after that column has been dropped.
dropFourth	Drop the fourth column in the set of tuples that satisfy the given predicate, and get a new tuple set after that column has been dropped.
dropSecond	Drop the second column in the set of tuples that satisfy the given predicate, and get a new tuple set after that column has been dropped.
dropThird	Drop the third column in the set of tuples that satisfy the given predicate, and get a new tuple set after that column has been dropped.
fifth	Get the set of fifth values in the set of tuples that satisfy the given predicate.
first	Get the set of first values in the set of tuples that satisfy the given predicate.
fourth	Get the set of fourth values in the set of tuples that satisfy the given predicate.
second	Get the set of second values in the set of tuples that satisfy the given predicate.
third	Get the set of third values in the set of tuples that satisfy the given predicate.

Modules

AllHoldsFor	A module with a single predicate, `holds`, that holds if all of the tuples in the current tuple set satisfy the given property `prop`.
AnyHoldsFor	A module with a single predicate, `holds`, that holds if any of the tuples in the current tuple satisfy the given property `prop`.
ContainedBy	A module with a single predicate, `holds`, that holds if all of the tuples in the current tuple set satisfy the given property `prop`.

ContainsAny	A module with a single predicate, `holds`, that holds if the current tuple set contains any of the tuples of the given tuple predicate `tp2`.
Difference	Creates a new tuple predicate that holds the elements only in the current tuple set, not the given one.
