.SH NAME
Dpkg::Deps::Multiple \- base module to represent multiple dependencies
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The Dpkg::Deps::Multiple module provides objects implementing various types
of dependencies. It is the base class for Dpkg::Deps::{AND,OR,Union}.
.SH METHODS
.IX Header "METHODS"
.ie n .IP "$dep = Dpkg::Deps::Multiple\->new(%opts);" 4
.el .IP "\f(CW$dep\fR = Dpkg::Deps::Multiple\->new(%opts);" 4
.IX Item "$dep = Dpkg::Deps::Multiple->new(%opts);"
Creates a new object.
.ie n .IP $dep\->\fBreset()\fR 4
.el .IP \f(CW$dep\fR\->\fBreset()\fR 4
.IX Item "$dep->reset()"
Clears any dependency information stored in \f(CW$dep\fR so that \f(CW$dep\fR\->\fBis_empty()\fR
returns true.
.ie n .IP $dep\->add(@deps) 4
.el .IP \f(CW$dep\fR\->add(@deps) 4
.IX Item "$dep->add(@deps)"
Adds new dependency objects at the end of the list.
.ie n .IP $dep\->\fBget_deps()\fR 4
.el .IP \f(CW$dep\fR\->\fBget_deps()\fR 4
.IX Item "$dep->get_deps()"
Returns a list of sub-dependencies.
.ie n .IP $dep\->\fBsort()\fR 4
.el .IP \f(CW$dep\fR\->\fBsort()\fR 4
.IX Item "$dep->sort()"
Sorts alphabetically the internal list of dependencies.
.ie n .IP $dep\->arch_is_concerned($arch) 4
.el .IP \f(CW$dep\fR\->arch_is_concerned($arch) 4
.IX Item "$dep->arch_is_concerned($arch)"
Returns true if at least one of the sub-dependencies apply to this
architecture.
.ie n .IP $dep\->reduce_arch($arch) 4
.el .IP \f(CW$dep\fR\->reduce_arch($arch) 4
.IX Item "$dep->reduce_arch($arch)"
Simplifies the dependencies to contain only information relevant to the
given architecture. The non-relevant sub-dependencies are simply removed.
.Sp
This trims off the architecture restriction list of Dpkg::Deps::Simple
objects.
.ie n .IP $dep\->\fBhas_arch_restriction()\fR 4
.el .IP \f(CW$dep\fR\->\fBhas_arch_restriction()\fR 4
.IX Item "$dep->has_arch_restriction()"
Returns the list of package names that have such a restriction.
.ie n .IP $dep\->\fBprofile_is_concerned()\fR 4
.el .IP \f(CW$dep\fR\->\fBprofile_is_concerned()\fR 4
.IX Item "$dep->profile_is_concerned()"
Returns true if at least one of the sub-dependencies apply to this profile.
.ie n .IP $dep\->\fBreduce_profiles()\fR 4
.el .IP \f(CW$dep\fR\->\fBreduce_profiles()\fR 4
.IX Item "$dep->reduce_profiles()"
Simplifies the dependencies to contain only information relevant to the
given profile. The non-relevant sub-dependencies are simply removed.
.Sp
This trims off the profile restriction list of Dpkg::Deps::Simple objects.
.ie n .IP $dep\->\fBis_empty()\fR 4
.el .IP \f(CW$dep\fR\->\fBis_empty()\fR 4
.IX Item "$dep->is_empty()"
Returns true if the dependency is empty and doesn't contain any useful
information. This is true when a (descendant of) Dpkg::Deps::Multiple
contains an empty list of dependencies.
.ie n .IP $dep\->merge_union($other_dep) 4
.el .IP \f(CW$dep\fR\->merge_union($other_dep) 4
.IX Item "$dep->merge_union($other_dep)"
This method is not meaningful for this object, and will always croak.
