NAME

PerlBean::Attribute - contains bean attribute information

SYNOPSIS

None. This is an abstract class.

ABSTRACT

Abstract PerlBean attribute information

DESCRIPTION

PerlBean::Attribute abstract class for bean attribute information. Attribute access methods are implemented and code and documentation generation interface methods are defined.

CONSTRUCTOR

new(OPT_HASH_REF)

Creates a new PerlBean::Attribute object. OPT_HASH_REF is a hash reference used to pass initialization options. OPT_HASH_REF is mandatory. On error an exception Error::Simple is thrown.

Options for OPT_HASH_REF may include:

default_value

Passed to set_default_value().

documented

Passed to set_documented(). Defaults to 1.

exception_class

Passed to set_exception_class(). Defaults to 'Error::Simple'.

mandatory

Passed to set_mandatory(). Defaults to 0.

method_base

Passed to set_method_base().

short_description

Passed to set_short_description().

Options for OPT_HASH_REF inherited through package PerlBean::Method::Factory may include:

method_factory_name

Passed to set_method_factory_name(). Mandatory option.

perl_bean

Passed to set_perl_bean().

METHODS

create_methods()

This is an interface method. Returns a list of PerlBean::Attribute::Method objects.

get_default_value()

Returns attribute default value.

get_exception_class()

Returns the class to throw when an exception occurs.

get_method_base()

Returns the method base name.

get_method_factory_name()

This method is inherited from package PerlBean::Method::Factory. Returns method factory's name.

get_package()

Returns the package name. The package name is obtained from the PerlBean to which the PerlBean::Attribute belongs. Or, if the PerlBean::Attribute does not belong to a PerlBean, main is returned.

get_package_us()

Calls get_package() and replaces :+ with C <_>.

get_perl_bean()

This method is inherited from package PerlBean::Method::Factory. Returns the PerlBean to which this method factory belongs.

get_short_description()

Returns the attribute description.

is_documented()

Returns whether the attribute is documented or not.

is_mandatory()

Returns whether the attribute is mandatory for construction or not.

mk_doc_clauses()

Returns a string containing the documentation for the clauses to which the contents the contents of the attribute must adhere.

set_default_value(VALUE)

Set attribute default value. VALUE is the value. On error an exception Error::Simple is thrown.

set_documented(VALUE)

State that the attribute is documented. VALUE is the value. Default value at initialization is 1. On error an exception Error::Simple is thrown.

set_exception_class(VALUE)

Set the class to throw when an exception occurs. VALUE is the value. Default value at initialization is Error::Simple. VALUE may not be undef. On error an exception Error::Simple is thrown.

set_mandatory(VALUE)

State that the attribute is mandatory for construction. VALUE is the value. Default value at initialization is 0. On error an exception Error::Simple is thrown.

set_method_base(VALUE)

Set the method base name. VALUE is the value. On error an exception Error::Simple is thrown.

set_method_factory_name(VALUE)

This method is inherited from package PerlBean::Method::Factory. Set method factory's name. VALUE is the value. VALUE may not be undef. On error an exception Error::Simple is thrown.

VALUE must match regular expression:

^\w+$

set_perl_bean(VALUE)

This method is inherited from package PerlBean::Method::Factory. Set the PerlBean to which this method factory belongs. VALUE is the value. On error an exception Error::Simple is thrown.

VALUE must be a (sub)class of:

PerlBean

set_short_description(VALUE)

Set the attribute description. VALUE is the value. On error an exception Error::Simple is thrown.

type()

Determines and returns the type of the attribute. The type is either BOOLEAN, SINGLE or MULTI.

write_constructor_option_code()

This is an interface method. Writes constructor code for the attribute option.

write_constructor_option_doc()

This is an interface method. Writes constructor documentation for the attribute option.

write_default_value()

This is an interface method. Returns a %DEFAULT_VALUE line string for the attribute.
