.SH NAME
Test2::Compare::Object \- Representation of an object during deep
comparison.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This class lets you specify an expected object in a deep comparison. You can
check the fields/elements of the underlying reference, call methods to verify
results, and do meta checks for object type and ref type.
.SH METHODS
.IX Header "METHODS"
.ie n .IP "$class = $obj\->meta_class" 4
.el .IP "\f(CW$class\fR = \f(CW$obj\fR\->meta_class" 4
.IX Item "$class = $obj->meta_class"
The meta\-class to be used when checking the object type. This is mainly listed
because it is useful to override for specialized object subclasses.
.Sp
This normally just returns Test2::Compare::Meta.
.ie n .IP "$class = $obj\->object_base" 4
.el .IP "\f(CW$class\fR = \f(CW$obj\fR\->object_base" 4
.IX Item "$class = $obj->object_base"
The base\-class to be expected when checking the object type. This is mainly
listed because it is useful to override for specialized object subclasses.
.Sp
This normally just returns \*(AqUNIVERSAL\*(Aq.
.ie n .IP $obj\->add_prop(...) 4
.el .IP \f(CW$obj\fR\->add_prop(...) 4
.IX Item "$obj->add_prop(...)"
Add a meta\-property to check, see Test2::Compare::Meta. This method
just delegates.
.ie n .IP $obj\->add_field(...) 4
.el .IP \f(CW$obj\fR\->add_field(...) 4
.IX Item "$obj->add_field(...)"
Add a hash\-field to check, see Test2::Compare::Hash. This method
just delegates.
.ie n .IP $obj\->add_item(...) 4
.el .IP \f(CW$obj\fR\->add_item(...) 4
.IX Item "$obj->add_item(...)"
Add an array item to check, see Test2::Compare::Array. This method
just delegates.
.ie n .IP "$obj\->add_call($method, $check)" 4
.el .IP "\f(CW$obj\fR\->add_call($method, \f(CW$check\fR)" 4
.IX Item "$obj->add_call($method, $check)"
.PD 0
.ie n .IP "$obj\->add_call($method, $check, $name)" 4
.el .IP "\f(CW$obj\fR\->add_call($method, \f(CW$check\fR, \f(CW$name\fR)" 4
.IX Item "$obj->add_call($method, $check, $name)"
.ie n .IP "$obj\->add_call($method, $check, $name, $context)" 4
.el .IP "\f(CW$obj\fR\->add_call($method, \f(CW$check\fR, \f(CW$name\fR, \f(CW$context\fR)" 4
.IX Item "$obj->add_call($method, $check, $name, $context)"
.PD
Add a method call check. This will call the specified method on your object and
verify the result. \f(CW$method\fR may be a method name, an array ref, or a coderef.
.Sp
If it\*(Aqs an arrayref, the first element must be the method name, and
the rest are arguments that will be passed to it.
.Sp
In the case of a coderef it can be helpful to provide an alternate
name. When no name is provided the name is either \f(CW$method\fR or the
string \*(Aq\e&CODE\*(Aq.
.Sp
If \f(CW$context\fR is \f(CW\*(Aqlist\*(Aq\fR, the method will be invoked in list
context, and the result will be an arrayref.
.Sp
If \f(CW$context\fR is \f(CW\*(Aqhash\*(Aq\fR, the method will be invoked in list
context, and the result will be a hashref (this will warn if the
method returns an odd number of values).
