NAME ^

PerlBean::Symbol - Symbol in a Perl bean

SYNOPSIS ^

 use strict;
 use PerlBean;
 use PerlBean::Attribute::Factory;
 
 my $bean = PerlBean->new( {
     package => 'MyPackage',
 } );
 my $factory = PerlBean::Attribute::Factory->new();
 my $attr = $factory->create_attribute( {
     method_factory_name => 'true',
     short_description => 'something is true',
 } );
 $bean->add_method_factory($attr);
 
 use IO::File;
 -d 'tmp' || mkdir('tmp');
 my $fh = IO::File->new('> tmp/PerlBean.pl.out');
 $bean->write($fh);

ABSTRACT ^

Symbol in a Perl bean

DESCRIPTION ^

PerlBean::Symbol allows to specify, declare, assign an export a symbol from a PerlBean.

CONSTRUCTOR ^

new( [ OPT_HASH_REF ] )

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

Options for OPT_HASH_REF may include:

assignment

Passed to set_assignment().

comment

Passed to set_comment().

declared

Passed to set_declared(). Defaults to 1.

description

Passed to set_description().

export_tag

Passed to set_export_tag(). Must be an ARRAY reference.

symbol_name

Passed to set_symbol_name().

volatile

Passed to set_volatile().

METHODS ^

add_export_tag(ARRAY)

Add additional values on the list of tags with which the symbol is exported. NOTE: The default tag lets the symbol be exported by default. ARRAY is the list value. The addition may not yield to multiple identical elements in the list. Hence, multiple occurrences of the same element cause the last occurrence to be inserted. On error an exception Error::Simple is thrown.

The values in ARRAY must match regular expression:
^\S*$
delete_export_tag(ARRAY)

Delete elements from the list of tags with which the symbol is exported. NOTE: The default tag lets the symbol be exported by default. Returns the number of deleted elements. On error an exception Error::Simple is thrown.

exists_export_tag(ARRAY)

Returns the count of items in ARRAY that are in the list of tags with which the symbol is exported. NOTE: The default tag lets the symbol be exported by default.

get_assignment()

Returns the value assigned to the symbol during declaration.

get_comment()

Returns the comment for the symbol declaration.

get_description()

Returns the description of the symbol.

get_symbol_name()

Returns the symbol's name (e.g. $var or @list).

is_declared()

Returns whether the symbol is to be declared with our or not.

is_volatile()

Returns whether the symbol is volatile or not.

set_assignment(VALUE)

Set the value assigned to the symbol during declaration. VALUE is the value. On error an exception Error::Simple is thrown.

set_comment(VALUE)

Set the comment for the symbol declaration. VALUE is the value. On error an exception Error::Simple is thrown.

set_declared(VALUE)

State that the symbol is to be declared with our. VALUE is the value. Default value at initialization is 1. On error an exception Error::Simple is thrown.

set_description(VALUE)

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

set_export_tag(ARRAY)

Set the list of tags with which the symbol is exported. NOTE: The default tag lets the symbol be exported by default absolutely. ARRAY is the list value. Each element in the list is allowed to occur only once. Multiple occurrences of the same element yield in the last occurring element to be inserted and the rest to be ignored. On error an exception Error::Simple is thrown.

The values in ARRAY must match regular expression:
^\S*$
set_symbol_name(VALUE)

Set the symbol's name (e.g. $var or @list). VALUE is the value. On error an exception Error::Simple is thrown.

VALUE must match regular expression:
^\S+$
set_volatile(VALUE)

State that the symbol is volatile. VALUE is the value. On error an exception Error::Simple is thrown.

values_export_tag()

Returns an ARRAY containing all values of the list of tags with which the symbol is exported. NOTE: The default tag lets the symbol be exported by default.

write(FILEHANDLE)

Writes the code for the symbol. FILEHANDLE is an IO::Handle object.
