DESCRIPTION
This class manages contacts. Currently, contacts are only associated with Bric::Biz::Person objects, but they could conceivably be associated with other objects, e.g., Bric::Biz::Org.

A contact is a method (other than snail mail) to contact a person. Default contact types include "Primary Email," "Secondary Email," "Office Phone," "Mobile Phone," "AOL Instant Messenger," etc. These types can be modified and new contact types can be added via this class' class methods. Each individual Bric::Biz::Contact object has an associated type, the type's description, and a value. Each is also associated with another object, so they will often be accessed from that object (see Bric::Biz::Person for an example).

INTERFACE

  Constructors

my $c = Bric::Biz::Contact->new()
my $c = Bric::Biz::Contact->new($init)
    Instantiates a Bric::Biz::Contact object. An anonymous hash of initial values may be passed. The supported initial value keys are:

    *   type

    *   value

    The active property will be set to true by default. Call $c->save() to save the new object.

    Throws:

    *   Incorrect number of args to Bric::_set().

    *   Bric::set() - Problems setting fields.

    Side Effects: NONE.

    Notes: NONE.

my $c = Bric::Biz::Contact->lookup({ id => $id })
    Looks up and instantiates a new Bric::Biz::Contact object based on the Bric::Biz::Contact object ID passed. If $id is not found in the database, lookup() returns undef.

    Throws:

    *   Too many Bric::Biz::Contact objects found.

    *   Unable to prepare SQL statement.

    *   Unable to connect to database.

    *   Unable to select column into arrayref.

    *   Unable to execute SQL statement.

    *   Unable to bind to columns to statement handle.

    *   Unable to fetch row from statement handle.

    Side Effects: If $id is found, populates the new Bric::Biz::Contact object with data from the database before returning it.

    Notes: NONE.

my (@contacts || $contact_aref) = Bric::Biz::Contact->list($params)
    Returns a list or anonymous array of Bric::Biz::Contact objects based on the search parameters passed via an anonymous hash. The supported lookup keys are:

    id  Contact ID. May use "ANY" for a list of possible values.

    type
        Contact type. May use "ANY" for a list of possible values.

    description
        Contact description. May use "ANY" for a list of possible values.

    value
        Contact value. May use "ANY" for a list of possible values.

    person_id
        ID of person object associated with contacts. May use "ANY" for a list of possible values.

    alertable
        Boolean indicating whether or not alerts can be sent to contacts of this type.

    Throws:

    *   Unable to prepare SQL statement.

    *   Unable to connect to database.

    *   Unable to select column into arrayref.

    *   Unable to execute SQL statement.

    *   Unable to bind to columns to statement handle.

    *   Unable to fetch row from statement handle.

    Side Effects: Populates each Bric::Biz::Contact object with data from the database before returning them all.

    Notes: NONE.

my $contacts_href = Bric::Biz::Contact->href($params)
    Works the same as list(), with the same arguments, except it returns a hash or hashref of Bric::Biz::Contact objects, where the keys are the contact IDs, and the values are the contact objects.

    Throws:

    *   Unable to prepare SQL statement.

    *   Unable to connect to database.

    *   Unable to select column into arrayref.

    *   Unable to execute SQL statement.

    *   Unable to bind to columns to statement handle.

    *   Unable to fetch row from statement handle.

    Side Effects: Populates each Bric::Biz::Contact object with data from the database before returning them all.

    Notes: NONE.

  Destructors

$p->DESTROY
    Dummy method to prevent wasting time trying to AUTOLOAD DESTROY.

    Throws: NONE.

    Side Effects: NONE.

    Notes: NONE.

  Public Class Methods

my (@c_ids || $c_ids_aref) = Bric::Biz::Contact->list_ids($params)
    Returns a list or anonymous array of Bric::Biz::Contact object IDs based on the search parameters passed via an anonymous hash. The supported lookup keys are the same as those for list().

    Throws:

    *   Unable to prepare SQL statement.

(@meths || $meths_aref) = Bric::Biz::Contact->my_meths(TRUE)
my (@meths || $meths_aref) = Bric::Biz:::Contact->my_meths(0, TRUE)
    Returns an anonymous hash of introspection data for this object. If called with a true argument, it will return an ordered list or anonymous array of introspection data. If a second true argument is passed instead of a first, then a list or anonymous array of introspection data will be returned for properties that uniquely identify an object (excluding "id", which is assumed).

    Each hash key is the name of a property or attribute of the object. The value for a hash key is another anonymous hash containing the following keys:

    name
        The name of the property or attribute. Is the same as the hash key when an anonymous hash is returned.

    disp
        The display name of the property or attribute.

    get_meth
        A reference to the method that will retrieve the value of the property or attribute.

    get_args
        An anonymous array of arguments to pass to a call to get_meth in order to retrieve the value of the property or attribute.

    set_meth
        A reference to the method that will set the value of the property or attribute.

    set_args
        An anonymous array of arguments to pass to a call to set_meth in order to set the value of the property or attribute.

    type
        The type of value the property or attribute contains. There are only three types:

        short
        date
        blob
    len If the value is a 'short' value, this hash key contains the length of the field.

    search
        The property is searchable via the list() and list_ids() methods.

    req The property or attribute is required.

    props
        An anonymous hash of properties used to display the property or attribute. Possible keys include:

        type
            The display field type. Possible values are

            text
            textarea
            password
            hidden
            radio
            checkbox
            select
        length
            The Length, in letters, to display a text or password field.

        maxlength
            The maximum length of the property or value - usually defined by the SQL DDL.
