EvaluateQueries
[source]¶ Bases:
ast.NodeVisitor
This class implements the parser to process White Matter Query Language modules. By inheriting from
ast.NodeVisitor
it uses a syntax close to the python language.Every node expression visitor has the following signature
Parameters: node : ast.Node
Returns: tracts : set
numbers of the tracts that result of this query
labels : set
numbers of the labels that are traversed by the tracts resulting from this query
Methods
generic_visit
(node)Called if no explicit visitor function exists for a node. process_assignment
(node)Processes the assignment operations process_relative_term
(node)Processes the relative terms rewrite_side_query
(node)Processes the side suffixes in a query visit
(node)Visit a node. visit_Assign
(node)visit_Attribute
(node)visit_AugAssign
(node)visit_BinOp
(node)visit_BoolOp
(node)visit_Call
(node)visit_Compare
(node)visit_Expr
(node)visit_For
(node)visit_Module
(node)visit_Name
(node)visit_Num
(node)visit_Str
(node)visit_UnaryOp
(node)-
relative_terms
= ['anterior_of', 'posterior_of', 'medial_of', 'lateral_of', 'inferior_of', 'superior_of']¶
-
process_relative_term
(node)[source]¶ Processes the relative terms
- anterior_of
- posterior_of
- superior_of
- inferior_of
- medial_of
- lateral_of
Parameters: node :
ast.Node
Parsed tree
Returns: tracts, labels
tracts : set
Numbers of the tracts that result of this query
labels : set
Numbers of the labels that are traversed by the tracts resulting from this query
-
process_assignment
(node)[source]¶ Processes the assignment operations
Parameters: node :
ast.Node
Parsed tree
Returns: queries_to_evaluate: dict
A dictionary or pairs ‘<name of the query>’= <node to evaluate>
