Any mappings that were found during the automatic analysis are made available on a drop-down list. For example, for a singly linked list, expressions for the head node, next node (given a node), and display value (given a node), are required. A configuration dialog allows the Java expressions that will be used to traverse the structure to be entered or edited. In cases where there are multiple mappings with similar confidence levels or where no mapping is found, the user is given the option of manually configuring the viewer (this can also be done while the viewer is in use). That is, an appropriate structural view will be displayed without user interaction. In most cases, one and only one mapping with a high confidence level will be found, and thus the mechanism will be transparent to the user. The structure mapping with the highest confidence level found during automatic identification, if it is significantly higher than the confidence level for other potential mappings, will be automatically used when a viewer is first opened for a particular class. An effect of employing this method is that for some structures, a more accurate identification may be achieved for non-empty instances than for empty ones. Since the viewer may have been initiated when the structure was in the process of being modified, a small number of errors in the structure will have little effect on the confidence level. Links in a potential binary tree or linked list will be examined to see if they do form a binary tree or linked list structure, and the confidence level will be modified appropriately. In addition to the name-based heuristics, link-based heuristics affect the confidence level for non-empty structure instances. In cases where automatic identification fails, the viewer can be configured manually.
Also, the use of unusual or meaningless class and field names will make correct identification less likely.
Currently, only English-language heuristics are applied. The downside of this technique is that it will only work if the language used for class and field names is known. The same class structure could also map to a doubly-linked list, but the class and field names make it very unlikely that this was the intention. For example, a class named MyTree containing a field called root, of a type with same-class- reference fields called left and right is highly likely to be a binary tree, and it is highly likely that the left and right fields are left and right binary tree links respectively. Name-based heuristics are used to assign a confidence level to each candidate. This method may lead to multiple possible structures and to multiple possible mappings from a class to a particular structure. For example, a singly linked list is typically implemented as a class with a field (the head node link) whose class type has one same- class-reference (to the next node).
