.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This package is used to generate classes based on hashrefs. Using this class
will give you a \f(CW\*(C`new()\*(C'\fR method, as well as generating accessors you request.
Generated accessors will be getters, \f(CW\*(C`set_ACCESSOR\*(C'\fR setters will also be
generated for you. You also get constants for each accessor (all caps) which
return the key into the hash for that accessor. Single inheritance is also
supported.
.SH "THIS IS A BUNDLED COPY OF HASHBASE"
.IX Header "THIS IS A BUNDLED COPY OF HASHBASE"
This is a bundled copy of Object::HashBase. This file was generated using
the
\&\f(CW\*(C`/home/exodist/perl5/perlbrew/perls/main/bin/hashbase_inc.pl\*(C'\fR

HashBase will not export \f(CW\*(C`new()\*(C'\fR if there is already a \f(CW\*(C`new()\*(C'\fR method in your
packages inheritance chain.
.Sp
\&\fBIf you do not want this method you can define your own\fR you just have to
declare it before loading Test2::Util::HashBase.
.Sp
.Vb 1
\&    package My::Package;
\&
\&    # predeclare new() so that HashBase does not give us one.

\&
\&    use Test2::Util::HashBase qw/foo bar baz/;
\&
\&    # Now we define our own new method.
\&    sub new { ... }
.Ve
.Sp
This makes it so that HashBase sees that you have your own \f(CW\*(C`new()\*(C'\fR method.
Alternatively you can define the method before loading HashBase instead of just
declaring it, but that scatters your use statements.
.Sp
The most common way to create an object is to pass in key/value pairs where
each key is an attribute and each value is what you want assigned to that
attribute. No checking is done to verify the attributes or values are valid,
you may do that in \f(CW\*(C`init()\*(C'\fR if desired.
.Sp
If you would like, you can pass in a hashref instead of pairs. When you do so
the hashref will be copied, and the copy will be returned blessed as an object.
There is no way to ask HashBase to bless a specific hashref.
.Sp
In some cases an object may only have 1 or 2 attributes, in which case a
hashref may be too verbose for your liking. In these cases you can pass in an
arrayref with only values. The values will be assigned to attributes in the
order the attributes were listed. When there is inheritance involved the
attributes from parent classes will come before subclasses.
.SS "\s-1HOOKS\s0"
.IX Subsection "HOOKS"
.ie n .IP "$self\->\fIinit()\fR" 4
.el .IP "\f(CW$self\fR\->\fIinit()\fR" 4
.IX Item "$self->init()"
This gives you the chance to set some default values to your fields. The only
argument is \f(CW$self\fR with its indexes already set from the constructor.
.Sp
\&\fBNote:\fR Test2::Util::HashBase checks for an init using \f(CW\*(C`$class\->can(\*(Aqinit\*(Aq)\*(C'\fR
during construction. It \s-1DOES NOT\s0 call \f(CW\*(C`can()\*(C'\fR on the created object. Also note
that the result of the check is cached, it is only ever checked once, the first
time an instance of your class is created. This means that adding an \f(CW\*(C`init()\*(C'\fR
method \s-1AFTER\s0 the first construction will result in it being ignored.
.SH "ACCESSORS"
.IX Header "ACCESSORS"
.SS "\s-1READ/WRITE\s0"
.IX Subsection "READ/WRITE"
To generate accessors you list them when using the module:
.PP
.Vb 1
\&    use Test2::Util::HashBase qw/foo/;
.Ve
.PP
This will generate the following subs in your namespace:
.IP "\fIfoo()\fR" 4
.IX Item "foo()"
Getter, used to get the value of the \f(CW\*(C`foo\*(C'\fR field.
.IP "\fIset_foo()\fR" 4
.IX Item "set_foo()"
Setter, used to set the value of the \f(CW\*(C`foo\*(C'\fR field.
.IP "\s-1\fIFOO\s0()\fR" 4
.IX Item "FOO()"
Constant, returns the field \f(CW\*(C`foo\*(C'\fR's key into the class hashref. Subclasses will
also get this function as a constant, not simply a method, that means it is
copied into the subclass namespace.
.Sp
The main reason for using these constants is to help avoid spelling mistakes
and similar typos. It will not help you if you forget to prefix the '+' though.
.SS "\s-1READ ONLY\s0"
.IX Subsection "READ ONLY"
.Vb 1
\&    use Test2::Util::HashBase qw/\-foo/;
.Ve
.IP "\fIset_foo()\fR" 4
.IX Item "set_foo()"
Throws an exception telling you the attribute is read-only. This is exported to
override any active setters for the attribute in a parent class.
.SS "\s-1DEPRECATED SETTER\s0"
.IX Subsection "DEPRECATED SETTER"
.Vb 1
\&    use Test2::Util::HashBase qw/^foo/;
.Ve
.IP "\fIset_foo()\fR" 4
.IX Item "set_foo()"
This will set the value, but it will also warn you that the method is
deprecated.
.SS "\s-1NO SETTER\s0"
.IX Subsection "NO SETTER"
.Vb 1
\&    use Test2::Util::HashBase qw/<foo/;
.Ve
.PP
Only gives you a reader, no \f(CW\*(C`set_foo\*(C'\fR method is defined at all.
.SS "\s-1NO READER\s0"
.IX Subsection "NO READER"
.Vb 1
\&    use Test2::Util::HashBase qw/>foo/;
.Ve
.PP
Only gives you a write (\f(CW\*(C`set_foo\*(C'\fR), no \f(CW\*(C`foo\*(C'\fR method is defined at all.
.SS "\s-1CONSTANT ONLY\s0"
.IX Subsection "CONSTANT ONLY"
.Vb 1
\&    use Test2::Util::HashBase qw/+foo/;
.Ve
.PP
This does not create any methods for you, it just adds the \f(CW\*(C`FOO\*(C'\fR constant.
.SH "SUBCLASSING"
.IX Header "SUBCLASSING"
You can subclass an existing HashBase class.
.PP
.Vb 2
\&    use base \*(AqAnother::HashBase::Class\*(Aq;
\&    use Test2::Util::HashBase qw/foo bar baz/;
.Ve
.PP
The base class is added to \f(CW@ISA\fR for you, and all constants from base classes
are added to subclasses automatically.
.SH "GETTING A LIST OF ATTRIBUTES FOR A CLASS"
.IX Header "GETTING A LIST OF ATTRIBUTES FOR A CLASS"
Test2::Util::HashBase provides a function for retrieving a list of attributes for an
Test2::Util::HashBase class.
.ie n .IP "@list = Test2::Util::HashBase::attr_list($class)" 4
.el .IP "\f(CW@list\fR = Test2::Util::HashBase::attr_list($class)" 4
.IX Item "@list = Test2::Util::HashBase::attr_list($class)"
.PD 0
.ie n .IP "@list = $class\->\fITest2::Util::HashBase::attr_list()\fR" 4
.el .IP "\f(CW@list\fR = \f(CW$class\fR\->\fITest2::Util::HashBase::attr_list()\fR" 4
.IX Item "@list = $class->Test2::Util::HashBase::attr_list()"
.PD
Either form above will work. This will return a list of attributes defined on
the object. This list is returned in the attribute definition order, parent
class attributes are listed before subclass attributes. Duplicate attributes
will be removed before the list is returned.
.Sp
\&\fBNote:\fR This list is used in the \f(CW\*(C`$class\->new(\e@ARRAY)\*(C'\fR constructor to
determine the attribute to which each value will be paired.
