Known Subclasses:

Marker class to indicate that the facet instance must be told its datatype when it is constructed.

This is necessary for facets like CF_minInclusive and CF_minExclusive, for which the value is determined by the base type definition of the associated STD. In some cases the value that must be used in the facet cannot be represented in the Python type used for the facet; see LateDatatypeBindsSuperclass.

Class Methods

[hide private]

LateDatatypeBindsSuperclass(cls)
Return true if false if the proposed datatype should be used, or True if the base type definition of the proposed datatype should be used.

source code

BindingValueDatatype(cls, value_type)
Find the datatype for facet values when this facet is bound to the given value_type.

Method Details

[hide private]

BindingValueDatatype(cls, value_type)
Class Method

source code

Find the datatype for facet values when this facet is bound to the given value_type.

If the value_type is an STD, the associated Python support datatype from this value_type scanning up through the base type hierarchy is used.

Class Variable Details

[hide private]

_LateDatatypeBindsSuperclass

The class variable that indicates that the Subclasses must override this variable with a value of True or False. The value is True iff the value used for the facet is not within the value space of the corresponding value datatype; for example, CF_minExclusive.

Value:

None
