=head1 NAME

P4::Integration

=head1 SYNOPSIS

    use P4;
    $p4 = new P4;
    $p4->Connect() or die( "Failed to connect to Perforce" );
    for $file in ( $p4->RunFilelog( "//depot/some/file" ) )
    {
    	for $rev in ( $file->Revisions() )
	{
	    for $integ in ( $rev->Integrations() )
	    {
	    	...
	    }
	}


=head1 DESCRIPTION

P4::Integration objects represent Perforce integration records.
While users are free to create objects of this class in their
own scripts, their primary use is that they are returned as
part of the output of C<P4::RunFilelog()>.

=head1 METHODS

=pod

=over

=item new()

=over

C<$integ = new P4::Integration( $how, $file, $srev, $erev );>

Creates a new P4::Integration object representing an 
integration to/from C<$file#$srev+1,$erev>. It's 
important to note that C<$srev> is always one lower 
than its actual value.

=item How()

=over

C<$integ-E<gt>How()>

Returns a string describing how the integration was 
resolved: 'copy from/into', 'branch from/into', 
'merge from/into' etc.

=back

=item File()

=over

C<$integ-E<gt>File()>

Returns the name of the file that is the source/target
of this integration. 

=back

=item SRev()

=over

C<$integ-E<gt>SRev()>

Returns the starting revision number for this integration.
Note that in the case of reverse integration records
('copy from' etc.), the starting revision value is 
always one lower than its actual value. So if SRev()
returns 0, then the real starting revision is 1.

=back

=item ERev()

=over

C<$integ-E<gt>ERev()>

Returns the ending revision number for this integration.
