class documentation

class BaseOpCode(outils.ValidatedSlots):

Known subclasses: ganeti.opcodes.OpCode

A simple serializable object.

This object serves as a parent class for OpCode without any custom field handling.

Class Method	`GetAllParams`	Compute list of all parameters for an opcode.
Method	`__getstate__`	Generic serializer.
Method	`__init__`	Constructor for BaseOpCode.
Method	`__setstate__`	Generic unserializer.
Method	`Validate`	Validate opcode parameters, optionally setting default values.

Inherited from ValidatedSlots:

Class Method	`GetAllSlots`	Compute the list of all declared slots for a class.
Class Variable	`__slots__`	Undocumented

@classmethod
def GetAllParams(cls): ¶

Compute list of all parameters for an opcode.

def __getstate__(self): ¶

overridden in ganeti.opcodes.OpCode

Generic serializer.

This method just returns the contents of the instance as a dictionary.

Returns
`dict`	the instance attributes and their values

def __init__(self, **kwargs): ¶

overrides ganeti.outils.ValidatedSlots.__init__

Constructor for BaseOpCode.

The constructor takes only keyword arguments and will set attributes on this object based on the passed arguments. As such, it means that you should not pass arguments which are not in the __slots__ attribute for this class.

def __setstate__(self, state): ¶

overridden in ganeti.opcodes.OpInstanceMultiAllocBase

Generic unserializer.

This method just restores from the serialized state the attributes of the current instance.

Parameters
state:`dict`	the serialized opcode data

def Validate(self, set_defaults): ¶

overrides ganeti.outils.ValidatedSlots.Validate

overridden in ganeti.opcodes.OpInstanceMultiAllocBase

Validate opcode parameters, optionally setting default values.

Parameters
set_defaults:bool	whether to set default values
Returns
NoneType	`None`, if the validation succeeds
Raises
`errors.OpPrereqError`	when a parameter value doesn't match requirements
