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:

attribute_name

Passed to set_attribute_name(). Mandatory option.

default_value

Passed to set_default_value().

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().

perl_bean

Passed to set_perl_bean().

short_description

Passed to set_short_description().

METHODS

get_overloaded_attribute()

Searches superclass packages for an identically named PerlBean::Attribute. If found it is returned otherwise undef is returned.

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 <_>.

type()

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

write_default_value(FILEHANDLE)

This is an interface method. Writes %DEFAULT_VALUE line for the attribute. FILEHANDLE is an IO::Handle object.

write_doc_clauses(FILEHANDLE)

Writes documentation for the clauses to which the contents the contents of the attribute must adhere. FILEHANDLE is an IO::Handle object.

write_doc_inherit_methods(FILEHANDLE)

This is an interface method. Writes documentation for the access methods for the attribute in the case the attibute methods are inherited. FILEHANDLE is an IO::Handle object.

write_doc_init(FILEHANDLE)

This is an interface method. Writes documentation for _initialize() for the attribute. FILEHANDLE is an IO::Handle object.

write_doc_methods(FILEHANDLE)

This is an interface method. Writes documentation for the access methods for the attribute. FILEHANDLE is an IO::Handle object.

write_methods(FILEHANDLE)

This is an interface method. Writes the access methods for the attribute. FILEHANDLE is an IO::Handle object.

write_opt_init(FILEHANDLE)

This is an interface method. Writes _initialize() option parsing code for the attribute. FILEHANDLE is an IO::Handle object.

set_attribute_name(VALUE)

Set attribute'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+$
get_attribute_name()

Returns attribute's name.

set_default_value(VALUE)

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

get_default_value()

Returns attribute's default value.

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.

get_exception_class()

Returns the class to throw when an exception occurs.

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.

is_mandatory()

Returns whether the attribute is mandatory for construction or not.

set_method_base(VALUE)

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

get_method_base()

Returns the method base name.

set_perl_bean(VALUE)

Set the PerlBean to which this attribute belongs. VALUE is the value. On error an exception Error::Simple is thrown.

VALUE must be a (sub)class of:
PerlBean
get_perl_bean()

Returns the PerlBean to which this attribute belongs.

set_short_description(VALUE)

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

get_short_description()

Returns the attribute description.
