=head1 NAME

Sun::Solaris::Exacct::Object::Item - exacct item manipulation

=head1 SYNOPSIS

use Sun::Solaris::Exacct::Object;

my $ea_item = Sun::Solaris::Exacct::Object::Item->new(

&EXT_UINT64 | &EXC_DEFAULT | &EXD_PROC_PID, $$);

This module is used for manipulating C<libexacct(3LIB)> data Items. A

libexacct Item is represented as an opaque reference blessed into the

C<Sun::Solaris::Exacct::Object::Item> class, which is a subclass of the

C<Sun::Solaris::Exacct::Object> class. The underlying libexacct data types are

mapped onto Perl types as follows:

B<C< libexacct type Perl internal type>>

EXT_UINT8 IV (integer)

EXT_UINT16 IV (integer)

EXT_UINT32 IV (integer)

EXT_UINT64 IV (integer)

EXT_DOUBLE NV (double)

EXT_STRING PV (string)

EXT_RAW PV (string)

EXT_EXACCT_OBJECT Sun::Solaris::Exacct::Object subclass

=head2 Constants

None.

=head2 Functions

None.

=head2 Class methods

Class methods include those inherited from the C<Sun::Solaris::Exacct::Object>

base class, plus the following:

B<C<new($catalog, $value)>>

This method creates and returns a new C<Sun::Solaris::Exacct::Object::Item>.

The catalog tag can be either an integer or a

C<Sun::Solaris::Exacct::Catalog>. This catalog tag controls the conversion of

the Perl value to the corresponding Perl exacct data type as described in the

table above. If the catalog tag has a type field of C<EXT_EXACCT_OBJECT>, the

value must be a reference to either an Item or a Group object and the passed

object is recursively copied and stored inside the new Item. Because the

returned Item is constant, it is impossible, for example, to create an Item

representing CPU seconds and subsequently modify its value or change its

catalog value. This behavior is intended to prevent mismatches between the

catalog tag and the data value.

=head2 Object methods

Object methods are those inherited from the C<Sun::Solaris::Exacct::Object>.

=head2 Exports

None.
