HollandHouse' UNISPOOL configuration
HH::Unispool::Config manages HollandHouse' UNISPOOL configuration files. Files can be read, written, generated from scratch and diff-ed.
HH::Unispool::Config
diff
Creates a new HH::Unispool::Config object. OPT_HASH_REF is a hash reference used to pass initialization options. On error an exception Error::Simple is thrown.
OPT_HASH_REF
Error::Simple
Options for OPT_HASH_REF may include:
diff_host
Passed to set_diff_host(). Defaults to 0.
diff_number
Passed to set_diff_number(). Defaults to 0.
diff_time
Passed to set_diff_time(). Defaults to 0.
diff_version
Passed to set_diff_version(). Defaults to 0.
filter
Passed to set_filter(). Must be an ARRAY reference.
ARRAY
host
Passed to set_host(). Defaults to the first part of &Sys::Hostname::hostname().
&Sys::Hostname::hostname()
scope
Passed to set_scope(). Defaults to HH::Unispool::Config::Scope->new().
system
Passed to set_system(). Must be an ARRAY reference.
time
Passed to set_time(). Defaults to 'time()'.
version
Passed to set_version(). Defaults to the version number of the installed UNISPOOL instance or 0.
0
Constructs a new HH::Unispool::Config object using a file. FILE is either a file name or an IO::Handle reference. On error an exception Error::Simple is thrown.
FILE
IO::Handle
Dumps the configuration of the UNISPOOL instance running on this machine into a temporary file, creates a new HH::Unispool::Config object using the temporary file and cleans up the temporary file. On error an exception Error::Simple is thrown.
Add additional values on the list of filters. 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.
VALUE
get_name()
Add additional values on the list of systems. 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.
Delete elements from the list of filters. Returns the number of deleted elements. On error an exception Error::Simple is thrown.
Delete elements from the list of systems. Returns the number of deleted elements. On error an exception Error::Simple is thrown.
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.
TO
Returns the count of items in ARRAY that are in the list of filters.
Returns the count of items in ARRAY that are in the list of systems.
Returns the host in the comment.
Returns not described option.
Returns the date in the comment in Unix time.
Returns the version in the comment.
Returns whether diff() should consider the host attribtute or not.
Returns whether diff() should consider the number attribtutes of devices and remote systems or not.
number
Returns whether diff() should consider the time attribtute or not.
Returns whether diff() should consider the version attribtute or not.
Returns an ARRAY containing the keys of the list of filters.
Returns an ARRAY containing the keys of the list of systems.
State that diff() should consider the host attribtute. VALUE is the value. Default value at initialization is 0. On error an exception Error::Simple is thrown.
State that diff() should consider the number attribtutes of devices and remote systems. VALUE is the value. Default value at initialization is 0. On error an exception Error::Simple is thrown.
State that diff() should consider the time attribtute. VALUE is the value. Default value at initialization is 0. On error an exception Error::Simple is thrown.
State that diff() should consider the version attribtute. VALUE is the value. Default value at initialization is 0. On error an exception Error::Simple is thrown.
Set the list of filters absolutely using values. 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.
Set the host in the comment. VALUE is the value. Default value at initialization is the first part of &Sys::Hostname::hostname(). VALUE may not be undef. On error an exception Error::Simple is thrown.
undef
Set not described option. VALUE is the value. Default value at initialization is HH::Unispool::Config::Scope->new(). VALUE may not be undef. On error an exception Error::Simple is thrown.
HH::Unispool::Config::Scope->new()
Set the list of systems absolutely using values. 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.
Set the date in the comment in Unix time. VALUE is the value. Default value at initialization is time(). VALUE may not be undef. On error an exception Error::Simple is thrown.
time()
Set the version in the comment. VALUE is the value. Default value at initialization is the version number of the installed UNISPOOL instance or 0. VALUE may not be undef. On error an exception Error::Simple is thrown.
Returns an ARRAY containing the values of the list of filters. If KEY_ARRAY contains one or more KEYs the values related to the KEYs are returned. If no KEYs specified all values are returned.
KEY_ARRAY
KEY
Returns an ARRAY containing the values of the list of systems. If KEY_ARRAY contains one or more KEYs the values related to the KEYs are returned. If no KEYs specified all values are returned.
Writes the object to file. FILE is either a file name or an IO::Handle reference. On error an exception Error::Simple is thrown.
Writes the object to file and loads the file into UNISPOOL using config -load. On error an exception Error::Simple is thrown.
