NAME

Muldis::D::Outdated::Core::Interval - Muldis D generic interval operators

VERSION

This document is Muldis::D::Outdated::Core::Interval version 0.148.2.

PREFACE

This document is part of the Muldis D language specification, whose root document is Muldis::D; you should read that root document before you read this one, which provides subservient details. Moreover, you should read the Muldis::D::Outdated::Core document before this current document, as that forms its own tree beneath a root document branch.

DESCRIPTION

This document describes essentially all of the core Muldis D generic interval operators, for the canonical interval types that are tuple or relation types with specific nonscalar headings. They can potentially be used with values of any data type as long as said data type has a (total) order-determination function defined for it, and all system-defined conceptually-ordered Muldis D scalar root types do.

This documentation is pending.

Most functions that should be in this document are pending.

Each of these functions is a wrapper over the order-determination function named sys.std.Core.Ordered.order when the latter function is primed by a misc_args argument of Tuple:D0 and by an is_reverse_order argument of Bool:False.

These functions' SPInterval-typed arguments' min and max attribute values must be of compatible declared types with the wrapped functions' topic and other parameters; otherwise these functions will fail|warn when the wrapped function would. Likewise, any other argument values would be compared to an interval's endpoints must be compatible with them. Likewise, said attributes of any multiplicity of SPInterval-typed arguments must be mutually compatible.

FUNCTIONS IMPLEMENTING VIRTUAL COLLECTIVE FUNCTIONS

sys.std.Core.Interval.SP.has_member

function has_member (Bool <-- coll : SPInterval, value : Ordered) implements sys.std.Core.Collective.has_member {...}

This function results in Bool:True iff its value argument is included within the interval defined by its coll argument, and Bool:False otherwise. That is, if conceptually the interval represents a set of values, this function tests if value is a member of coll.

sys.std.Core.Interval.SP.has_not_member

function has_not_member (Bool <-- coll : SPInterval, value : Ordered) implements sys.std.Core.Collective.has_not_member {...}

This function is exactly the same as sys.std.Core.Interval.has_member except that it results in the opposite boolean value when given the same arguments.

sys.std.Core.Interval.SP.value_is_member

function value_is_member (Bool <-- value : Ordered, coll : SPInterval) implements sys.std.Core.Collective.value_is_member {...}

This function is an alias for sys.std.Core.Interval.SP.has_member. This function results in Bool:True iff its value argument is included within the interval defined by its coll argument, and Bool:False otherwise. That is, if conceptually the interval represents a set of values, this function tests if value is a member of coll.

sys.std.Core.Interval.SP.value_is_not_member

function value_is_not_member (Bool <-- value : Ordered, coll : SPInterval) implements sys.std.Core.Collective.value_is_not_member {...}

This function is an alias for sys.std.Core.Interval.SP.has_not_member. This function is exactly the same as sys.std.Core.Interval.SP.value_is_member except that it results in the opposite boolean value when given the same arguments.

sys.std.Core.Interval.MP.has_member

function has_member (Bool <-- coll : MPInterval, value : Ordered) implements sys.std.Core.Collective.has_member {...}

This function results in Bool:True iff its value argument is included within the interval defined by its coll argument, and Bool:False otherwise. That is, if conceptually the interval represents a set of values, this function tests if value is a member of coll.

sys.std.Core.Interval.MP.has_not_member

function has_not_member (Bool <-- coll : MPInterval, value : Ordered) implements sys.std.Core.Collective.has_not_member {...}

This function is exactly the same as sys.std.Core.Interval.has_member except that it results in the opposite boolean value when given the same arguments.

sys.std.Core.Interval.MP.value_is_member

function value_is_member (Bool <-- value : Ordered, coll : MPInterval) implements sys.std.Core.Collective.value_is_member {...}

This function is an alias for sys.std.Core.Interval.MP.has_member. This function results in Bool:True iff its value argument is included within the interval defined by its coll argument, and Bool:False otherwise. That is, if conceptually the interval represents a set of values, this function tests if value is a member of coll.

sys.std.Core.Interval.MP.value_is_not_member

function value_is_not_member (Bool <-- value : Ordered, coll : MPInterval) implements sys.std.Core.Collective.value_is_not_member {...}

This function is an alias for sys.std.Core.Interval.MP.has_not_member. This function is exactly the same as sys.std.Core.Interval.MP.value_is_member except that it results in the opposite boolean value when given the same arguments.
