.SH "NAME"
Dpkg::Deps::AND \- list of AND dependencies
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class represents a list of dependencies that must be met at the same
time. It inherits from Dpkg::Deps::Multiple.
.SH "METHODS"
.IX Header "METHODS"
.ie n .IP "$dep\->output([$fh])" 4
.el .IP "\f(CW$dep\fR\->output([$fh])" 4
.IX Item "$dep->output([$fh])"
The output method uses \*(L", \*(R" to join the list of sub-dependencies.
.ie n .IP "$dep\->implies($other_dep)" 4
.el .IP "\f(CW$dep\fR\->implies($other_dep)" 4
.IX Item "$dep->implies($other_dep)"
Returns 1 when \f(CW$dep\fR implies \f(CW$other_dep\fR. Returns 0 when \f(CW$dep\fR implies
\&\s-1NOT\s0($other_dep). Returns undef when there's no implication. \f(CW$dep\fR and
\&\f(CW$other_dep\fR do not need to be of the same type.
.ie n .IP "$dep\->get_evaluation($facts)" 4
.el .IP "\f(CW$dep\fR\->get_evaluation($facts)" 4
.IX Item "$dep->get_evaluation($facts)"
Evaluates the dependency given a list of installed packages and a list of
virtual packages provided. These lists are part of the Dpkg::Deps::KnownFacts
object given as parameters.
.Sp
Returns 1 when it's true, 0 when it's false, undef when some information
is lacking to conclude.
.ie n .IP "$dep\->simplify_deps($facts, @assumed_deps)" 4
.el .IP "\f(CW$dep\fR\->simplify_deps($facts, \f(CW@assumed_deps\fR)" 4
.IX Item "$dep->simplify_deps($facts, @assumed_deps)"
Simplifies the dependency as much as possible given the list of facts (see
object Dpkg::Deps::KnownFacts) and a list of other dependencies that are
known to be true.
