.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Handles \s-1CRUD\s0 for Zabbix trigger objects.
.PP
This is a subclass of \f(CW\*(C`Zabbix::API::CRUDE\*(C'\fR; see there for inherited methods.
.SH "METHODS"
.IX Header "METHODS"
.IP "\fIcollides()\fR" 4
.IX Item "collides()"
Returns true if the trigger exists with this description, false otherwise.
.IP "\fIhosts()\fR" 4
.IX Item "hosts()"
Accessor for a local \f(CW\*(C`hosts\*(C'\fR attribute, which it also sets from the server data
when necessary (when it is not yet set, which happens when the trigger has just
been fetched or immediately after a pull or push \*(-- this is because a trigger's
notion of its host(s) is \*(L"whatever is referred to in the trigger expression\*(R").
The value returned is an arrayref of \f(CW\*(C`Zabbix::API::Host\*(C'\fR instances.
.IP "\fIitems()\fR" 4
.IX Item "items()"
Same as \f(CW\*(C`hosts()\*(C'\fR, for items.
.IP "\fIdependencies()\fR" 4
.IX Item "dependencies()"
Same as \f(CW\*(C`hosts()\*(C'\fR, for dependencies (which are \f(CW\*(C`Trigger\*(C'\fR instances).
.IP "add_dependency(\s-1DEPENDENCY\s0)" 4
.IX Item "add_dependency(DEPENDENCY)"
Add a dependency to this trigger.  The dependency can be a trigger \s-1ID\s0 (an
integer), or a \f(CW\*(C`Zabbix::API::Trigger\*(C'\fR instance.
.IP "remove_dependency(\s-1DEPENDENCY\s0)" 4
.IX Item "remove_dependency(DEPENDENCY)"
Remove a dependency from this trigger.  The dependency can be a trigger \s-1ID\s0 (an
integer), or a \f(CW\*(C`Zabbix::API::Trigger\*(C'\fR instance.  Unlike the web \s-1API\s0 method,
this method removes a \fBsingle\fR dependency.
.SH "BUGS AND LIMITATIONS"
.IX Header "BUGS AND LIMITATIONS"
The \f(CW\*(C`expression\*(C'\fR data attribute stored in \f(CW\*(C`Zabbix::API::Trigger\*(C'\fR instances is
actually an expression \s-1ID\s0.  This is what the web \s-1API\s0 returns.  Expressions are
also not mapped by the web \s-1API\s0, so this is all you get (well, you can get the
list of hosts and items mentioned in the expression).  If you plan on using this
distribution to manipulate trigger expressions, a workaround is to have the
trigger just use a calculated item in a very simple expression, since items work
as expected.
.PP
Since the web \s-1API\s0 does not expose a method through which dependencies can be
removed individually, the \f(CW\*(C`remove_dependency\*(C'\fR method works around this by
deleting all dependencies then adding back the rest.
