NAME

Pegasus::DAX::Metadata - stores a Pegasus piece of meta data.

SYNOPSIS

    use Pegasus::DAX::Metadata; 

    my $a = Pegasus::DAX::Profile->new( 'key', 'type', 'fubar' ); 
    my $b = Pegasus::DAX::Profile->new( key => 'foo'
                                      , type => 'integer'
                                      , value => 'bar' );

DESCRIPTION

This class remembers a Pegasus meta data. The internal transformation- and replica catalog may use meta data associated with entries.

METHODS

new()

new( $key, $type, $value )

new( a => b, c => d, ... )

new( { a => b, c => d, ... } )

The default constructor will create an empty instance whose scalar attributes can be adjusted using the getters and setters provided by the AUTOLOAD inherited method.

When invoked with exactly 3 arguments, the first argument is the meta data key, the second argument the type identifier, and the third argument the value to set.

Other means of construction is to use named lists.

key

Setter and getter for a key string. The key value may be of restricted range, dependinng on the namespace, but this is not checked at this point.

type

Setter and getter for a type string. Types are not standardized in any way.

value

Setter and getter for the value to be transported.

toXML( $handle, $indent, $xmlns )

The purpose of the toXML function is to recursively generate XML from the internal data structures. The first argument is a file handle open for writing. This is where the XML will be generated. The second argument is a string with the amount of white-space that should be used to indent elements for pretty printing. The third argument may not be defined. If defined, all element tags will be prefixed with this name space.
