METHODS

       LedgerSMB::DBObject::Payment->new()
	   Inherited from LedgerSMB::DBObject.	Please see that documnetation for details.

       $payment->get_open_accounts()
	   This function returns a list of open accounts depending on the $payment->{account_class} property.  If this property is 1, it returns a
	   list of vendor accounts, for 2, a list of customer accounts are returned.

	   The returned list of hashrefs is stored in the $payment->{accounts} property.  Each hashref has the following keys:	id (entity id),
	   name, and entity_class.

	   An account is considered open if there are outstanding, unpaid invoices attached to it.  Customer/vendor payment threshold is not
	   considered for this calculation.

       text_amount($value)
	   Returns the textual representation, as defined in localization rules, for the numeric value passed.

       get_metadata()
	   Semi-private method for preparing the object for other tasks, such as displaying payment options.

       search()
	   Seturns a series of payments matching the search criteria.

	   Search results are also stored at $payment->{search_results}.

       get_open_accounts()
	   Returns a list of open accounts for the payment operation.

	   These are also stored on $payment->{accounts}

       $payment->get_entity_credit_account()
	   Returns billing information for the current account, and saves it to an arrayref at $payment->{entity_accounts}/

       $payment->get_all_accounts()
	   This function returns a list of open or closed accounts depending on the $payment->{account_class} property.  If this property is 1, it
	   returns a list of vendor accounts, for 2, a list of customer accounts are returned.

	   The returned list of hashrefs is stored in the $payment->{accounts} property.  Each hashref has the following keys:	id (entity id),
	   name, and entity_class.

       $payment->reverse()
	   This function reverses a payment.  A payment is defined as one source ($payment->{source}) to one cash account ($payment->{cash_accno})
	   to one date ($payment->{date_paid}) to one vendor/customer ($payment->{credit_id}, $payment->{account_class}).  This reverses the
	   entries with that source.

       $payment->get_open_invoices()
	   This function returns a list of open invoices depending on the $payment->{account_class}, $payment->{entity_id}, and $payment->{curr}
	   properties.	Account classes follow the conventions above.  This list is hence specific to a customer or vendor and currency as well.

	   The returned list of hashrefs is stored in the $payment->{open_invoices} property. Each hashref has the following keys:  id (entity
	   id), name, and entity_class.

       $payment->get_open_invoice()
	   This function is an especific case of get_open_invoices(), because get_open_invoice() can search for a specific invoice, wich can be
	   searched by the $payment->{invnumber} variable

       $payment->get_all_contact_invoices()
	   This function returns a list of open accounts depending on the $payment->{account_class} property.  If this property is 1, it returns a
	   list of vendor accounts, for 2, a list of customer accounts are returned.  Attached to each account is a list of open invoices.  The
	   data structure is somewhat complex.

	   Each item in the list has the following keys: contact_id, contact_name,  account_number, total_due, and invoices.

	   The invoices entry is a reference to an array of hashrefs.  Each of these hashrefs has the following keys: invoice_id, invnumber,
	   invoice_date, amount, discount, and due.

	   These are filtered based on the (required) properties: $payment->{account_class}, $payment->{business_type}, $payment->{date_from},
	   $payment->{date_to}, and $payment->{ar_ap_accno}.

	   The $payment->{ar_ap_accno} property is used to filter out by AR or AP account.

	   The following can also be optionally passed: $payment->{batch_id}.  If this is patched, vouchers in the current batch will be picked up
	   as well.

	   The returned list of hashrefs is stored in the $payment->{contact} property.  Each hashref has the following keys:  id (entity id),
	   name, and entity_class.

       list_open_projects
	   This method gets the current date attribute, and provides a list of open projects.  The list is attached to $self->{projects} and
	   returned.

       list_departments
	   This method gets the type of document as a parameter, and provides a list of departments of the required type.  The list is attached to
	   $self->{departments} and returned.

       list_open_vc
	   This method gets the type of vc (vendor or customer) as a parameter, and provides a list of departments of the required type.  The list
	   is attached to $self->{departments} and returned.

       get_open_currencies
	   This method gets a list of the open currencies inside the database, it requires that $self->{account_class} (must be 1 or 2)  exist to
	   work.

	   WARNING THIS IS NOT BEEING USED BY THE SINGLE PAYMENT SYSTEM....

       list_accounting
	   This method lists all accounts that match the role specified in account_class property and are available to store the payment or
	   receipts.  =back

       list_overpayment_accounting
	   This method lists all accounts that match the role specified in account_class property and are available to store an overpayment /
	   advanced payment / pre-payment.  =back

       get_sources
	   This method builds all the possible sources of money, in the future it will look inside the DB.  =back

       get_exchange_rate(currency, date)
	   This method gets the exchange rate for the specified currency and date

       get_default_currency
	   This method gets the default currency =back

       get_current_date
	   This method returns the system's current date

       get_vc_info
	   This method returns the contact informatino for a customer or vendor according to $self->{account_class}

       get_payment_detail_data
	   This method sets appropriate project, department, etc. fields.

       post_bulk
	   This function posts the payments in bulk.  Note that queue_payments is not a common setting and rather this provides a hook for an add-
	   on.

	   This API was developed early in 1.3 and is likely to change for better encapsulation.  Currenty it uses the following structure:

	   Within the main hashref:

	   contact_count
	       The number of payments.	One per contact.

	   contact_$row
	       for (1 .. contact_count), contact_$_ is the entity credit account's id associated with the current contact.  We will call this
	       $contact_id below.

	       For each contact id, we have the following, suffixed with _$contact_id:

	       source
	       invoice_count
		   Number of invoices to loop through

	       invoice_${contact_id}_$row
		   for $row in (1 .. invoice_count), each this provides the transaction id of the invoice.

	       Each invoice has the following attributes, suffxed with ${invoice_id}

	       amount
	       paid
	       net

	   In the future the payment posting API will become more standardized and the conversion between flat and hierarchical representation
	   will be moved to the workflow scripts.

       check_job
	   To be moved into payment_queue addon.

       post_payment
	   This method uses payment_post to store a payment (not a bulk payment) on the database.

       gather_printable_info
	   This method retrieves all the payment related info needed to build a document and print it. IT IS NECESSARY TO ALREADY HAVE payment_id
	   on $self

       get_open_overpayment_entities
	   This method retrieves all the entities with the specified account_class which have unused overpayments

       get_unused_overpayments
	   This is a simple wrapper around payment_get_unused_overpayments sql function.

       get_available_overpayment_amount
	   Simple wrapper around payment_get_available_overpayment_amount sql function.

       init
	   Initializes the num2text system

       num2text
	   Translates numbers into words.
