.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The Basic::Global subclass of MakeMethods provides basic accessors for data shared by an entire class, sometimes called \*(L"static\*(R" or \*(L"class data.\*(R"
.SS "Calling Conventions"
.IX Subsection "Calling Conventions"
When you \f(CW\*(C`use\*(C'\fR this package, the method names you provide
as arguments cause subroutines to be generated and installed in
your module.
.PP
See \*(L"Calling Conventions\*(R" in Class::MakeMethods::Basic for a summary, or \*(L"\s-1USAGE\*(R"\s0 in Class::MakeMethods for full details.
.SS "Declaration Syntax"
.IX Subsection "Declaration Syntax"
To declare methods, pass in pairs of a method-type name followed
by one or more method names. Valid method-type names for this
package are listed in \*(L"\s-1METHOD GENERATOR TYPES\*(R"\s0.
.PP
See \*(L"Declaration Syntax\*(R" in Class::MakeMethods::Basic for more
syntax information.
.SH "METHOD GENERATOR TYPES"
.IX Header "METHOD GENERATOR TYPES"
.SS "scalar \- Shared Accessor"
.IX Subsection "scalar - Shared Accessor"
For each method name passed, uses a closure to generate a subroutine with the following characteristics:
.IP "\(bu" 4
May be called as a class method, or equivalently, on any object instance.
.IP "\(bu" 4
Stores a global value accessible only through this method.
.IP "\(bu" 4
If called without any arguments returns the current value.
.IP "\(bu" 4
If called with an argument, stores that as the value, and returns it,
.PP
Sample declaration and usage:
.PP
.Vb 5
\&  package MyObject;
\&  use Class::MakeMethods::Basic::Hash (
\&    scalar => \*(Aqfoo\*(Aq,
\&  );
\&  ...
\&  
\&  # Store value
\&  MyObject\->foo(\*(AqFoozle\*(Aq);
\&  
\&  # Retrieve value
\&  print MyObject\->foo;
.Ve
.SS "array \- Shared Ref Accessor"
.IX Subsection "array - Shared Ref Accessor"
For each method name passed, uses a closure to generate a subroutine with the following characteristics:
.IP "\(bu" 4
May be called as a class method, or equivalently, on any object instance.
.IP "\(bu" 4
Stores a global value accessible only through this method.
.IP "\(bu" 4
The value will be a reference to an array (or undef).
.IP "\(bu" 4
If called without any arguments, returns the current array-ref value (or undef).
.IP "\(bu" 4
If called with one argument, uses that argument as an index to retrieve from the referenced array, and returns that value (or undef). If the single argument is an array ref, then a slice of the referenced array is returned.
.IP "\(bu" 4
If called with a list of index-value pairs, stores the value at the given index in the referenced array. If the value was previously undefined, a new array is autovivified. The current value in each position will be overwritten, and later arguments with the same index will override earlier ones. Returns the current array-ref value.
.PP
Sample declaration and usage:
.PP
.Vb 5
\&  package MyObject;
\&  use Class::MakeMethods::Basic::Hash (
\&    array => \*(Aqbar\*(Aq,

.SS "hash \- Shared Ref Accessor"
.IX Subsection "hash - Shared Ref Accessor"
For each method name passed, uses a closure to generate a subroutine with the following characteristics:
.IP "\(bu" 4
May be called as a class method, or equivalently, on any object instance.
.IP "\(bu" 4
Stores a global value accessible only through this method.
.IP "\(bu" 4
The value will be a reference to a hash (or undef).
.IP "\(bu" 4
If called without any arguments, returns the current hash-ref value (or undef).
.IP "\(bu" 4
If called with one argument, uses that argument as an index to retrieve from the referenced hash, and returns that value (or undef). If the single argument is an array ref, then a slice of the referenced hash is returned.
.IP "\(bu" 4
If called with a list of key-value pairs, stores the value under the given key in the referenced hash. If the value was previously undefined, a new hash is autovivified. The current value under each key will be overwritten, and later arguments with the same key will override earlier ones. Returns the current hash-ref value.

Sample declaration and usage:
