Test for SQL NOT BETWEEN.

Method Summary
	`__init__(self, parent)`
	`asSQL(self, paramDict)` Return a SQL code snippet for this condition element.
	`evaluate(self, lookup)` Evaluate a condition tree using a given lookup dictionary for field- and parameter-values.
Inherited from GCondition
	`buildFromList(self, prefixList)` This function creates a (partial) condition tree from a prefix notation list.
	`prefixNotation(self)` This function returns the prefix notation of an element and all it's children.
	`validate(self)` This function calls validate () on all it's children.
Inherited from GObj
	`__getitem__(self, key)`
	`__setitem__(self, key, value)`
	`_dumpXML_(self, lookupDict, treeDump, gap, xmlnamespaces, textEncoding, stripPrefixes, escape)` Dumps an XML representation of the object
	`buildAndInitObject(self, **params)` This is a convenience function for applications NOT using GParser to load an object tree.
	`buildObject(self, **params)` A convenience function for applications NOT using GParser to load an object tree.
string	`getXmlTag(self, stripPrefixes)` Returns the xml tag to be used to represent the object.

	`showTree(self, indent)` A recusive function to print an indented text representation of the GObj tree from this object down.
	`walk(self, function, args, *parms)` Function that recursively walks down through a tree of `ParserObj` instances and applies a function to them.
Inherited from GTriggerCore
	`__repr__(self)`
	`create_namespace_object(self, global_namespace, namespace_name)` Construct a namespace object tree from an XML (`definitions.GObjects.GObj`) object tree.
	`get_namespace_object(self)` Return the namespace object that mirrors this object in the action/trigger namespace.
Inherited from ParserObj
	`_diffActionWalker_(self, obj, action)` Set the action attribute of a given object to the specified action.
	`_getAsContents_(self)` Get the contents of this object.
	`_id_(self, maxIdLength)` Return a compareable and identifying id of an object within a tree.
	`_set_initial_attributes_(self, attributes)` Set attributes loaded by GParser.
	`addChild(self, child)` Add an object to the list of children
	`assign(self, source, recursive)` Assign all attributes from a given object to this one.
	`diff(self, goal, maxIdLength)` Build an object tree representing the difference between two object trees.
	`dumpXML(self, lookupDict, treeDump, gap, xmlnamespaces, textEncoding, stripPrefixes, escape)` Return a XML representation of the object.
	`findChildNamed(self, name, childType)` Moves downward though the children of an object till it finds the child with the specified name.
	`findChildOfType(self, childType, includeSelf, allowAllChildren)` Moves downward through the children of an object till it finds the child of the specified type.
	`findChildrenOfType(self, childType, includeSelf, allowAllChildren)` Find all children of a specific type.
	`findParentOfType(self, parentType, includeSelf)` Moves upward though the parents of an object till it finds the parent of the specified type.
	`getChildrenAsContent(self)` Returns the content of any GContent objects that are children of this object.
	`getDescription(self)` Return a useful description of the object.
any	`getParent(self)` Returns the immediate parent of an object instance in a GObj tree.
	`merge(self, other, maxIdLength, overwrite)` Merge another object tree into this tree.
	`setParent(self, newParent)` Set the immediate parent of an object instance in a GObj tree
Inherited from object
	`__delattr__(...)` x.__delattr__('name') <==> del x.name
	`__getattribute__(...)` x.__getattribute__('name') <==> x.name
	`__hash__(x)` Return hash(x)...
	`__new__(T, S, ...)` Return a new object with type S, a subtype of T...
	`__reduce__(...)` helper for pickle
	`__reduce_ex__(...)` helper for pickle
	`__setattr__(...)` x.__setattr__('name', value) <==> x.name = value
	`__str__(x)` Return str(x)...

Instance Variable Summary
Inherited from GCondition
	`_maxChildren_`: if not None specifies the maximum number of children allowed for a condition element.
	`_operator_`: unicode string defining the operator used for SQL transformation of a condition element.

Method Details

init(self, parent=None)
(Constructor)

Overrides:: gnue.common.datasources.GConditions.GConditionElement.__init__

asSQL(self, paramDict)

Return a SQL code snippet for this condition element.

Parameters:: paramDict - parameter dictionary which will be extended

Returns:: SQL code for the condition element

Overrides:: gnue.common.datasources.GConditions.GCondition.asSQL

evaluate(self, lookup)

Evaluate a condition tree using a given lookup dictionary for field- and parameter-values. Evaluation stops on the first False result.

Parameters:: lookup - dictionary used for lookups of field- and parameter-values.

Returns:: True or False

Raises:: ArgumentCountError - if the number of child elements somewhere in the tree is incorrect.; MissingFieldError - if not all fields appearing in the condition tree are assigned a value in the lookup dictionary.; ConversionRuleError - if any operation is given two incompatible arguments.; ConversionError - if the type conversion needed to make arguments of an operation comatible fails.
