| - | ===== ''getName()'' and ''getPath()'' Methods ===== | + | ===== Names and Paths ===== |
| - | The ''getName()'' always returns the simple name of a constituent. For binary-class relationships and method invocations, the name returned by ''getName()'' is less important, it could simply be ''Method Invocation'', for example. For a first-class entity, though, it is important, for example ''getName()'' returns ''Constituent'' for ''padl.kernel.IConstituent''. Here are other examples of ''getName()'' values: | + | The ''getName()'' always returns the simple name of a constituent.
