Class constructor Creates a new Unix::Conf::Bind8::Conf::Zone object and returns it if successful, an Err object otherwise. Do not use this constructor directly. Use Unix::Conf::Bind8::Conf::new_zone () instead.

name ()
 Arguments
 'zone',    # optional

Object method. Get/Set object's name attribute. If argument is passed, the method tries to set the name attribute to 'zone', and returns true if successful, an Err object otherwise. If no argument is passed, returns the name of the zone, if defined, an Err object otherwise.

class ()
 Arguments
 'class',     # optional

Object method. Get/Set object's class attribute. If argument is passed, the method tries to set the class attribute to 'class', and returns true if successful, an Err object otherwise. If no argument is passed, returns the class of the zone, if defined, an Err object otherwise.

file ()
 Arguments
 'file',    # optional

Object method. Get/Set the object's file attribute. If argument is passed, the method tries to set the file attribute to 'file', and returns true if successful, and Err object otherwise. If no argument is passed, returns the file of the zone, if defined, an Err object otherwise.

type ()
 Arguments
 'type',    # optional

Object method. Get/Set the object's type attribute. If argument is passed, the method tries to set the type attribute to 'type', and returns true if successful, an Err object otherwise. If no argument is passed, returns the type of the zone, if defined, an Err object otherwise.

forward ()
notify ()
dialup ()
 Arguments
 SCALAR,                # 'yes'|'no'|0|1

Object method Get/set corresponding attribute in the invocant. If argument is passed, the method tries to set it as the value and returns true if successful, an Err object otherwise. If no argument is passed the value of that attribute is returned if defined, an Err object otherwise.

check_names ()
 Arguments
 string,                # 'warn'|'fail'|'ignore'

Object method Get/set corresponding attribute in the invocant. If argument is passed, the method tries to set it as the value and returns true if successful, an Err object otherwise. If no argument is passed the value of that attribute is returned if defined, an Err object otherwise.

transfer_source ()
 Arguments
 string,                # IPv4 address in dotted quad notation

Object method Get/set corresponding attribute in the invocant. If argument is passed, the method tries to set it as the value and returns true if successful, an Err object otherwise. If no argument is passed the value of that attribute is returned if defined, an Err object otherwise.

max_transfer_time_in ()
 Arguments
 number,                

Object method Get/set corresponding attribute in the invocant. If argument is passed, the method tries to set it as the value and returns true if successful, an Err object otherwise. If no argument is passed the value of that attribute is returned if defined, an Err object otherwise.
