jpl::fli::Prolog Class Reference

List of all members.


Detailed Description

This class consists only of constants (static finals) and static native methods. The constants and methods defined herein are in (almost) strict 1-1 correspondence with the functions in the Prolog FLI by the same name (except without the PL_, SQ_, etc. prefixes).

See the file jpl_fli_Prolog.c for the native implementations of these methods. Refer to your local Prolog FLI documentations for the meanings of these methods, and observe the following:

<menu> The types and signatures of the following methods are almost in 1-1 correspondence with the Prolog FLI. The Prolog types term_t, atom_t, functor_t, etc. are mirrored in this package with classes by the same name, making the C and Java uses of these interfaces similar. As term_t, functor_t, etc. types are Java classes, they are passed to these methods by value; however, calling these methods on such class instances does have side effects. In general, the value fields of these instances will be modified, in much the same way the term_t, functor_t, etc. Prolog instances would be modified. The exceptions to this rule occur when maintaining the same signature would be impossible, e.g., when the Prolog FLI functions require pointers; in this case, the signatures have been modified to take *Holder classes (Int, Double, String, etc.), to indicate a call by reference parameter. Functions which take variable-length argument lists in C take arrays in Java; from Java 1.1 onwards, anonymous arrays can be used e.g. Term[] { new Atom("a"), new Atom ("b") } </menu>
