class Boolean_DT(BaseType_DT) |

Boolean-integer data-type specifier

- Method resolution order:
- Boolean_DT
- BaseType_DT
- DataTypeDefinition
- object
Class methods defined here:
- check(cls, value) from type
- Determine whether value conforms to definition
- coerce(cls, value) from type
- Coerce value to Boolean value
Accepted Values:
(any value in self.falseValues) -- False
__nonzero__ False -- False
otherwise True
Data and other attributes defined here:
- baseType = <type 'bool'>
- bool(x) -> bool
Returns True when the argument x is true, False otherwise.
The builtins True and False are the only two instances of the class bool.
The class bool is a subclass of the class int, and cannot be subclassed.
- dataType = 'bool'
- falseValues = (0, None, '0', 'zero', 'null', 'none', 'false', 'f', 'no', '')
Class methods inherited from BaseType_DT:
- factories(cls) from type
- Determine a sequence of factory objects
Static methods inherited from BaseType_DT:
- __new__(cls, *args, **named)
- Create a new instance of our base-type
Data and other attributes inherited from DataTypeDefinition:
- __dict__ = <dictproxy object at 0x01A30610>
- dictionary for instance variables (if defined)
- __weakref__ = <attribute '__weakref__' of 'DataTypeDefinition' objects>

- BaseType_DT
- DataTypeDefinition
- object
Data and other attributes defined here:

Convert a string or number to an integer, if possible. A floating point
argument will be truncated towards zero (this does not include a string
representation of a floating point number!) When converting a string, use
the optional base. It is an error to supply a base when converting a
non-string. If the argument is outside the integer range a long object
will be returned instead.
