Predicates
| accesses | Holds if this data flow node accesses attribute named |
| 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 |
| getAttributeNameExpr | Gets the expression node that defines the attribute being accessed, if any. This is usually an identifier or literal. |
| getObject | Gets the data flow node corresponding to the object whose attribute is being read or written. |
| mayHaveAttributeName | Holds if this attribute reference may access an attribute named |
| unknownAttribute | Holds if a name could not be determined for this attribute. |
