Predicates

getCallable	Gets the callable that this parameter belongs to.
getName	Gets the name of the parameter, if any.
getParameter	Gets the parameter corresponding to this node, if any.

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