NAME

Iterator::Array::Jagged - Iterate through multiple jagged arrays

SYNOPSIS

use Iterator::Array::Jagged;

# Build up a set of data:
my @data = ();
for my $var ( 1...3 )
{
	my @set = ();
	for my $val ( 1...2 )
	{
		push @set, "var_$var=val_$val";
	}# end for()
	push @data, \@set;
}# end for()

my $iterator = Iterator::Array::Jagged->new( data => \@data );
while( my @set = $iterator->next )
{
	print "Next set: '" . join("&", @set) . "'\n";
}# end while()

The above code prints the following:

Next set: 'var1=val1&var2=val1&var3=val1'
Next set: 'var1=val2&var2=val1&var3=val1'
Next set: 'var1=val1&var2=val2&var3=val1'
Next set: 'var1=val2&var2=val2&var3=val1'
Next set: 'var1=val1&var2=val1&var3=val2'
Next set: 'var1=val2&var2=val1&var3=val2'
Next set: 'var1=val1&var2=val2&var3=val2'
Next set: 'var1=val2&var2=val2&var3=val2'

DESCRIPTION

Iterator::Array::Jagged can permute through sets of "jagged" arrays - arrays of varying lengths.

Iterator::Array::Jagged works much like the odometer in an automobile. Except that each set of "numbers" can have any kind of data you want, and each set can contain 1 or more elements.

METHODS

new( %args )

Constructor. %args should included the element data which contains the arrayref of arrayrefs that you wish to iterate through.

next( )

Returns an array representing the next iteration of the permutation of your data set. See the synopsis for an example.
