Predicates

backtrack	Gets a node that may flow into this one using one heap and/or interprocedural step.
flowsTo	Holds if this `LocalSourceNode` can flow to `nodeTo` in one or more local flow steps.
getALocalUse	Gets a node to which data may flow from this node in zero or more local data-flow steps.
getAMethodCall	Gets a method call where this node flows to the receiver.
getAMethodCall	Gets a call to a method named `name`, where this node flows to the receiver.
getAnAttributeRead	Gets a call `obj.name` with no arguments, where this node flows to `obj`.
getAnAttributeWriteValue	Gets a value assigned to `name` on this object, such as the `x` in `obj.name = x`.
getAnElementRead	Gets an access to an element on this node, such as `obj[key]`.
getAnElementRead	Gets an access to the element `key` on this node, such as `obj[:key]`.
getAnElementWriteValue	Gets a value stored as an element on this node, such as the `x` in `obj[key] = x`.
getAnElementWriteValue	Gets the `x` in `obj[key] = x`, where this node flows to `obj`.
track	Starts tracking this node forward using API graphs.
track	Gets a node that this node may flow to using one heap and/or interprocedural step.

Inherited predicates

asCallable	Gets the callable corresponding to this block, lambda expression, or call to `proc` or `lambda`.	from Node
asExpr	Gets the expression corresponding to this node, if any.	from Node
asParameter	Gets the parameter corresponding to this node, if any.	from Node
backtrack	Starts backtracking from this node using API graphs.	from Node
getALocalSource	Gets a local source node from which data may flow to this node in zero or more local data-flow steps.	from Node
getAPredecessor	Gets a data flow node from which data may flow to this node in one local step.	from Node
getASuccessor	Gets a data flow node to which data may flow from this node in one local step.	from Node
getConstantValue	Gets the constant value of this expression, if any.	from Node
getEnclosingMethod	Gets the enclosing method, if any.	from Node
getLocation	Gets the location 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
toString	Gets a textual representation of this node.	from Node
