NAME

       Proc::ProcessTable - Perl extension to access the unix process table

SYNOPSIS

	 use Proc::ProcessTable;

	 $p = new Proc::ProcessTable( 'cache_ttys' => 1 );
	 @fields = $p->fields;
	 $ref = $p->table;

DESCRIPTION

       Perl interface to the unix process table.

METHODS

       new Creates a new ProcessTable object. The constructor can take the following flags:

	   enable_ttys -- causes the constructor to use the tty determination code, which is the default behavior.  Setting this to 0 diables this
	   code, thus preventing the module from traversing the device tree, which on some systems, can be quite large and/or contain invalid
	   device paths (for example, Solaris does not clean up invalid device entries when disks are swapped).  If this is specified with
	   cache_ttys, a warning is generated and the cache_ttys is overridden to be false.

	   cache_ttys -- causes the constructor to look for and use a file that caches a mapping of tty names to device numbers, and to create the
	   file if it doesn't exist (this file is /tmp/TTYDEVS by default). This feature requires the Storable module.

       fields
	   Returns a list of the field names supported by the module on the current architecture.

       table
	   Reads the process table and returns a reference to an array of Proc::ProcessTable::Process objects. Attributes of a process object are
	   returned by accessors named for the attribute; for example, to get the uid of a process just do:

	   $process->uid

	   The priority and pgrp methods also allow values to be set, since these are supported directly by internal perl functions.

EXAMPLES

	# A cheap and sleazy version of ps
	use Proc::ProcessTable;

	$FORMAT = "%-6s %-10s %-8s %-24s %s
";
	$t = new Proc::ProcessTable;
	printf($FORMAT, "PID", "TTY", "STAT", "START", "COMMAND");
	foreach $p ( @{$t->table} ){
	  printf($FORMAT,
		 $p->pid,
		 $p->ttydev,
		 $p->state,
		 scalar(localtime($p->start)),
		 $p->cmndline);
	}

	# Dump all the information in the current process table
	use Proc::ProcessTable;

	$t = new Proc::ProcessTable;

	foreach $p (@{$t->table}) {
	 print "--------------------------------
";
	 foreach $f ($t->fields){
	   print $f, ":  ", $p->{$f}, "
";
	 }
	}

SQL::Translator::Schema::Index(3pm)			User Contributed Perl Documentation		       SQL::Translator::Schema::Index(3pm)

NAME

       SQL::Translator::Schema::Index - SQL::Translator index object

SYNOPSIS

	 use SQL::Translator::Schema::Index;
	 my $index = SQL::Translator::Schema::Index->new(
	     name   => 'foo',
	     fields => [ id ],
	     type   => 'unique',
	 );

DESCRIPTION

       "SQL::Translator::Schema::Index" is the index object.

       Primary and unique keys are table constraints, not indices.

METHODS

   new
       Object constructor.

	 my $schema = SQL::Translator::Schema::Index->new;

   fields
       Gets and set the fields the index is on.  Accepts a string, list or arrayref; returns an array or array reference.  Will unique the field
       names and keep them in order by the first occurrence of a field name.

	 $index->fields('id');
	 $index->fields('id', 'name');
	 $index->fields( 'id, name' );
	 $index->fields( [ 'id', 'name' ] );
	 $index->fields( qw[ id name ] );

	 my @fields = $index->fields;

   is_valid
       Determine whether the index is valid or not.

	 my $ok = $index->is_valid;

   name
       Get or set the index's name.

	 my $name = $index->name('foo');

   options
       Get or set the index's options (e.g., "using" or "where" for PG).  Returns an array or array reference.

	 my @options = $index->options;

   table
       Get or set the index's table object.

	 my $table = $index->table;

   type
       Get or set the index's type.

	 my $type = $index->type('unique');

       Get or set the index's type.

       Currently there are only four acceptable types: UNIQUE, NORMAL, FULL_TEXT, and SPATIAL. The latter two might be MySQL-specific. While both
       lowercase and uppercase types are acceptable input, this method returns the type in uppercase.

   equals
       Determines if this index is the same as another

	 my $isIdentical = $index1->equals( $index2 );
