=head1 NAME

Lab::XPRESS::Sweep::Repeater - Simple repeater

=head1 VERSION

version 3.823

=head1 SYNOPSIS

	use Lab::XPRESS::hub;
	my $hub = new Lab::XPRESS::hub();
	
	
	
	my $repeater = $hub->Sweep('Repeater',
		{
		repetitions => 5
		});

=head1 DESCRIPTION

Parent: Lab::XPRESS::Sweep

The Lab::XPRESS::Sweep::Repeater class implements a simple repeater module in the Lab::XPRESS::Sweep framework.

=head1 CONSTRUCTOR

	my $repeater = $hub->Sweep('Repeater',
		{
		repetitions => 5
		});

Instantiates a new repeater with 5 repetitions. Alternatively 

	my $repeater_array = $hub->Sweep('Repeater',
		{
		repetitions => [10, 20, 30, 40, 50]
		});

Instantiates also a repeater with 5 repetitions. However, the function

	$repeater->get_value(); # <-- returns 1,2,3,4,5 depending on the repetition,
	$repeater->get_array(); # <-- returns 10,20,30,40,50 depending on the repetition.  
.

=head1 PARAMETERS

=head2 repetitions [int / array] (default = 1)

number of repetitions. default value is 1, negative values indicate a infinit number of repetitions.
When an array is given, the number of reetitions corresponds to the length of the array.

=head2 id [string] (default = 'Repeater')

Just an ID.

=head2 filename_extention [string] (default = '#=')

Defines a postfix, that will be appended to the filenames if necessary.

=head2 delay_before_loop [float] (default = 0)

defines the time in seconds to wait after the starting point has been reached.

=head2 delay_in_loop [float] (default = 0)

This parameter is relevant only if mode = 'step' or 'list' has been selected. 
Defines the time in seconds to wait after the value for the next step has been reached.

=head2 delay_after_loop [float] (default = 0)

Defines the time in seconds to wait after the sweep has been finished. This delay will be executed before an optional backsweep or optional repetitions of the sweep.

=head1 METHODS

=head2 get_value()

Returns an integer number n corresponding to the nth repetition or if an array @a was given for the parameter 'repetitions' it returns @a[n].  

=head1 CAVEATS/BUGS

probably none
