Known Subclasses:

TemplateMultiConstraint

Constraints for checking membership of a set of values

These constraints require the value they constrain to be either a member of a set of values, or not a member.

Valid operators:

ONE OF
NONE OF

These constraints are similar in use to List constraints, with the following differences:

The list in this case is a defined set of values that is passed along with the query itself, rather than anything stored independently on a server.
The object of the constaint is the value of an attribute, rather than an object's identity.

Instance Methods

__init__(self, path, op, values, code='A') source code

to_string(self)
Provide a human readable representation of the logic.

source code

to_dict(self)
Return a dict object which can be used to construct a DOM element with the appropriate attributes.

init(self, path, op, values, code=`'A'`)
(Constructor)

source code

Constructor

Parameters:

path (string) - The path to constrain. Here it must be an attribute of some object.
op (string) - The relationship between the path and the path provided (must be a valid operator)
values (set or list) - The set of values which the object of the constraint either must or must not belong to.
code (string) - The code for this constraint (default = "A")

Overrides: object.__init__

to_string(self)

source code

Provide a human readable representation of the logic. This method is called by repr.

Overrides: pathfeatures.PathFeature.to_string

to_dict(self)

source code

Return a dict object which can be used to construct a DOM element with the appropriate attributes.

Overrides: pathfeatures.PathFeature.to_dict
