Members

The Object class appends the above list of methods names to __reserved__ from PStorBaseClass with the exception of keys, get__key__, and update_handler.

Methods

_init_( connection, key )

• creates a reference object that refers to a mutable object in the persistent storage system.

_setattr_( name, value )

• sets the attribute name to value.

_delattr_( attr )

• deletes the attribute attr.

getattributes()

• returns a list of the names of a Object's attributes.

getcontents()

• returns a list containing the __key__ of each attribute.

getncontents()

• get a count of the contents

getnrcontents()

• get a recursive count of the contents

hasattr( attr )

• returns true if the Object has an attribute attr

_getattribute_( self, attr, python_object=1 )

• attempts to return the value of attr. It first looks for the attribute in the database, then it looks for the attribute in the Object's Class (which is still on the database). If the attribute is not in either of those it looks for the attribute in the python object itself.

_str_()

• returns Object(%s) where %s is repr(self.__key__).

_repr_()

• functional the same as __str__.

keys()

• not fully implemented.

get__key__()

• returns __key__.

update_handler( name )

• a method meant to be overwritten. Called when the value of attribute is modified. name is the attribute that was modified.

Method( key=None )

• convenience method to instantiate and return a new Method type object with a given key.
