DESCRIPTION

HH::Unispool::Config::Entry::System groups remote systems and devices from UNISPOOL configuration. In different words, it groups from a configuration file anything between

 * Miscellaneous configuration items for [...]

line and the following

 * Miscellaneous configuration items for [...]

line or the following

 * End of configuration dumped on host ...

line.

CONSTRUCTOR

Creates a new HH::Unispool::Config::Entry::System object. OPT_HASH_REF is a hash reference used to pass initialization options. OPT_HASH_REF is mandatory. On error an exception Error::Simple is thrown.

Options for OPT_HASH_REF may include:

central_console_node: Passed to set_central_console_node(). Defaults to 'SYSLOG'.
clean_on_weekdays_only: Passed to set_clean_on_weekdays_only(). Defaults to 0.
date_format: Passed to set_date_format(). Defaults to HH::Unispool::Config::DateFormat->new( { date_format = 'DD/MM/YY' } )>.

new_from_tokenizer(TOKENIZER)

This method is an implementation from package HH::Unispool::Config::Entry. Constructs a new HH::Unispool::Config::Entry object using tokens. TOKENIZER is an HH::Unispool::Config::File::Tokenizer reference. On error an exception Error::Simple is thrown.

METHODS

add_device( [ VALUE ... ] )

Add additional values on the list of devices for the system. Each VALUE is an object out of which the id is obtained through method get_name(). The obtained key is used to store the value and may be used for deletion and to fetch the value. 0 or more values may be supplied. Multiple occurrences of the same key yield in the last occurring key to be inserted and the rest to be ignored. Each key of the specified values is allowed to occur only once. On error an exception Error::Simple is thrown.

The values in ARRAY must be a (sub)class of:

HH::Unispool::Config::Entry::Device

add_remote_system( [ VALUE ... ] )

Add additional values on the list of remote systems for the system. Each VALUE is an object out of which the id is obtained through method get_name(). The obtained key is used to store the value and may be used for deletion and to fetch the value. 0 or more values may be supplied. Multiple occurrences of the same key yield in the last occurring key to be inserted and the rest to be ignored. Each key of the specified values is allowed to occur only once. On error an exception Error::Simple is thrown.

The values in ARRAY must be a (sub)class of:

diff(TO [, DIFF_NUMBER])

This method is overloaded from package HH::Unispool::Config::Entry. Finds differences between two objects. In diff terms, the object is the from object and the specified TO parameter the to object. TO is a reference to an identical object class. Returns an empty string if no difference found and a difference descritpion string otherwise. On error an exception Error::Simple is thrown. Paremeter DIFF_NUMBER if specified, overrules the value of get_diff_number.
