Known Subclasses:

TemplateTernaryConstraint

Constraints for broad, general searching over all fields

These constraints request a wide-ranging search for matching fields over all aspects of an object, including up to coercion from related classes.

Valid operators:

LOOKUP

To aid disambiguation, Ternary constaints accept an extra_value as well as the main value.

Instance Methods

[hide private]

__init__(self, path, op, value, extra_value=None, 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, value, extra_value=None, code=`'A'`)

Constructor

Parameters:

path (string) - The path to constrain. Here is must be a class, or a reference to a class.
op (string) - The relationship between the path and the path provided (must be a valid operator)
value (string) - The value to check other fields against.
extra_value (string) - A further value for disambiguation. The meaning of this value varies by class and configuration. For example, if the class of the object is Gene, then extra_value will refer to the Organism.
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
