Fields

Predicates

getFunction	Gets the function to which this node belongs.
getLocalVariable	Gets the uninitialized local variable corresponding to this node.
getLocation	Gets the location of this element.
getType	Gets the type of this node.
toString	Gets a textual representation of this element.

Inherited predicates

asDefiningArgument	Gets the argument that defines this `DefinitionByReferenceNode`, if any. This predicate should be used instead of `asExpr` when referring to the value of a reference argument after the call has returned. For example, in `f(&x)`, this predicate will have `&x` as its result for the `Node` that represents the new value of `x`.	from Node
asExpr	Gets the expression corresponding to this node, if any. This predicate only has a result on nodes that represent the value of evaluating the expression. For data flowing out of an expression, like when an argument is passed by reference, use `asDefiningArgument` instead of `asExpr`.	from Node
asParameter	Gets the parameter corresponding to this node, if any.	from Node
asPartialDefinition	Gets the expression that is partially defined by this node, if any.	from Node
asUninitialized	Gets the uninitialized local variable corresponding to this node, if any.	from Node
getEnclosingCallable	INTERNAL: Do not use. Alternative name for `getFunction`.	from Node
getTypeBound	Gets an upper bound on the type of this node.	from Node
hasLocationInfo	Holds if this element is at the specified location. The location spans column `startcolumn` of line `startline` to column `endcolumn` of line `endline` in file `filepath`. For more information, see Locations.	from Node
