Known Subclasses:

Simple interface allowing any class to be properly duplicated

Note: to implement this interface, implement createInstance and copyFrom in your class

Instance Methods

[hide private]

__copyTo(self, instance, *args, **kwargs)
Internal Method with minimal checking

source code

duplicate(self, *args, **kwargs)
Implements a c-style copy constructor by creating a new instance of self and applying the copyFrom methods from base to all classes implementing the copyfrom method.

source code

copyTo(self, instance, *args, **kwargs)
Copy the values of ourselves onto the given instance which must be an instance of our class to be compatible.

source code

copyToOther(self, instance, *args, **kwargs)
As copyTo, but does only require the objects to have a common base.

source code

Inherited from Interface: supports

Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __init__, __new__, __reduce__, __reduce_ex__, __repr__, __setattr__, __sizeof__, __str__, __subclasshook__

Interface

createInstance(self, *args, **kwargs)
Create and Initialize an instance of self.__class__( ...

source code

copyFrom(self, other, *args, **kwargs)
Copy the data from other into self as good as possible Only copy the data that is unique to your specific class - the data of other classes will be taken care of by them !

source code

Properties

[hide private]

Inherited from object: __class__

Method Details

[hide private]

createInstance(self, *args, **kwargs)

source code

Create and Initialize an instance of self.__class__( ... ) based on your own data

Returns:: new instance of self

Notes:

using self.__class__ instead of an explicit class allows derived classes that do not have anything to duplicate just to use your implementeation
you must support args and kwargs if one of your iDuplicate bases does

copyFrom(self, other, *args, **kwargs)

source code

Copy the data from other into self as good as possible Only copy the data that is unique to your specific class - the data of other classes will be taken care of by them !

Note: you must support args and kwargs if one of your iDuplicate bases does

duplicate(self, *args, **kwargs)

source code

Implements a c-style copy constructor by creating a new instance of self and applying the copyFrom methods from base to all classes implementing the copyfrom method. Thus we will call the method directly on the class

Parameters:

args - passed to copyFrom and createInstance method to give additional directions
kwargs - see param args

copyTo(self, instance, *args, **kwargs)

source code

Copy the values of ourselves onto the given instance which must be an instance of our class to be compatible. Only the common classes will be copied to instance

Returns:: altered instance

Note: instance will be altered during the process

copyToOther(self, instance, *args, **kwargs)

source code

As copyTo, but does only require the objects to have a common base. It will match the actually compatible base classes and call copyFrom if possible. As more checking is performed, this method performs worse than copyTo
