This module is part of distribution Finance-Bank-Bankwest v1.2.8.

This distribution's version numbering follows the conventions defined at L<semver.org|http://semver.org/>.

=head1 SYNOPSIS

    $transaction->date;         # '31/12/2012'
    $transaction->date_dt;      # a DateTime instance
    $transaction->narrative;    # '1 BANK CHEQUE FEE - BWA CUSTOMER'
    $transaction->cheque_num;   # undef
    $transaction->amount;       # -10.00
    $transaction->type;         # 'FEE'

    SAME_TRANSACTION if $this_txn->equals($other_txn);
    SAME_TRANSACTION if $this_txn eq $other_txn;
    DIFFERENT_TRANSACTION if $this_txn ne $other_txn;

=head1 DESCRIPTION

Instances of this module are returned by
L<Finance::Bank::Bankwest::Session/transactions>.

=head1 ATTRIBUTES

=head2 date

A string in C<DD/MM/YYYY> format representing the date of the
transaction.

=head2 date_dt

I<Added in v1.2.0.>

The L</date> as a L<DateTime> instance with a floating time zone.

I<require>-s the DateTime module when used.  C<use DateTime> in any
code that relies on this attribute to prevent runtime failures caused
by the DateTime module not being installed.

=head2 narrative

A description of the transaction.

=head2 cheque_num

The cheque number for cheque withdrawals, or C<undef> if not applicable.

=head2 amount

A positive or negative value representing the credit or debit value of
the transaction respectively, or C<undef> if not applicable (such as
for fee notices or declined transactions).

=head2 type

The transaction "type."  Defined for every transaction in savings
accounts (e.g. Zero Transaction).  Not defined for every transaction in
credit card accounts.

If defined, may be one of the following values (although Bankwest may
not always assign the most relevant code to a particular transaction):

=head1 METHODS

=head2 equals

I<Added in v1.1.0.>

    if ($this_txn->equals($other_txn)) {
        # $this_txn and $other_txn represent the exact same transaction
        ...
    }

True if both this transaction and the specified one represent an
identical transaction; false otherwise.

Perl's C<eq> and C<ne> operators are also L<overload>-ed for
Transaction objects, allowing the following code to work as expected:

    if ($this_txn eq $other_txn) {
        # $this_txn and $other_txn represent the exact same transaction
        ...
    }

    if ($this_txn ne $other_txn) {
        # $this_txn and $other_txn DO NOT represent the exact same transaction
        ...
    }
