NAME

ExportTo - export function/method to namespace

SYNOPSIS

package From;

sub function1{
  # ...
}

sub function2{
  # ...
}

sub function3{
  # ...
}

use ExportTo (NameSpace1 => [qw/function1 function2/], NameSpace2 => [qw/function3/]);

# Now, function1 and function2 are exported to 'NameSpace1' namespace.
# function3 is exported to 'NameSpace2' namespace.

# If 'NameSpace1'/'NameSpace2' namespace has same name function/method,
# such a function/method is not exported and ExportTo croaks.
# but if you want to override, you can do it as following.

use ExportTo (NameSpace1 => qw/+function1 function2/);

# if adding + to function/method name,
# This override function/method which namespace already has with exported funtion/method.

use ExportTo ('+NameSpace' => qw/function1 function2/);

# if you add + to namespace name, all functions are exported even if namespace already has function/method.

DESCRIPTION

This module allow you to export/override subroutine/method to one namespace. It can be used for mix-in, for extension of modules not using inheritance.

FUNCTION/METHOD

export_to

export_to(PACKAGE_NAME => [qw/FUNCTION_NAME/]);
ExportTo->export_to(PACKAGE_NAME => [qw/FUNCTION_NAME/]);

These are as same as following.

use ExportTo(PACKAGE_NAME => [qw/FUNCTION_NAME/]);

But, 'use' is needed to declare after declaration of function/method. using 'export_to', you can write anywhere.
