Predicates

reads

Holds if this attribute read reads the attribute named attrName on the object object.

Inherited predicates

accesses	Holds if this data flow node accesses attribute named `attrName` on object `object`.	from AttrRef
asCfgNode	Gets the control-flow node corresponding to this node, if any.	from Node
asExpr	Gets the expression 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
flowsTo	Holds if this `LocalSourceNode` can flow to `nodeTo` in one or more local flow steps.	from LocalSourceNode
getACall	Gets a call to this node.	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
getAMethodCall	Gets a call to the method `methodName` on this node.	from LocalSourceNode
getAnAnnotatedInstance	Gets a node that has this node as its annotation.	from LocalSourceNode
getAnAttributeRead	Gets a read of any attribute on this node.	from LocalSourceNode
getAnAttributeRead	Gets a read of attribute `attrName` on this node.	from LocalSourceNode
getAnAttributeReference	Gets a reference (read or write) of any attribute on this node.	from LocalSourceNode
getAnAttributeReference	Gets a reference (read or write) of attribute `attrName` on this node.	from LocalSourceNode
getAnAttributeWrite	Gets a write of any attribute on this node.	from LocalSourceNode
getAnAttributeWrite	Gets a write of attribute `attrName` on this node.	from LocalSourceNode
getAnAwaited	Gets an awaited value from this node.	from LocalSourceNode
getAttributeName	Gets the name of the attribute being read or written. For dynamic attribute accesses, this method is not guaranteed to return a result. For such cases, using `mayHaveAttributeName` may yield better results.	from AttrRef
getAttributeNameExpr	Gets the expression node that defines the attribute being accessed, if any. This is usually an identifier or literal.	from AttrRef
getEnclosingCallable	Gets the enclosing callable of this node.	from Node
getLocation	Gets the location of this node	from Node
getObject	Gets the data flow node corresponding to the object whose attribute is being read or written.	from AttrRef
getScope	Gets the scope of this node.	from Node
getSubscript	Gets a subscript of this node.	from LocalSourceNode
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
mayHaveAttributeName	Holds if this attribute reference may access an attribute named `attrName`. Uses local data flow to track potential attribute names, which may lead to imprecision. If more precision is needed, consider using `getAttributeName` instead.	from AttrRef
toString	Gets a textual representation of this element.	from Node
track	Gets a node that this node may flow to using one heap and/or interprocedural step.	from LocalSourceNode
unknownAttribute	Holds if a name could not be determined for this attribute.	from AttrRef
