Predicates
| getValue | Gets the data flow node corresponding to the value that is written to the attribute. |
Inherited predicates
| accesses | Holds if this data flow node accesses attribute named | 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 |
| asVar | Gets the ESSA variable corresponding to this node, if any. | 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 |
| 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 | 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 |
| hasLocationInfo | Holds if this element is at the specified location. The location spans column | from Node |
| mayHaveAttributeName | Holds if this attribute reference may access an attribute named | from AttrRef |
| toString | Gets a textual representation of this element. | from Node |
| unknownAttribute | Holds if a name could not be determined for this attribute. | from AttrRef |
