Hello I am trying to use the uniqueId() function, and find some examples. Basically I want to use the CAS unique ID as the unique id Feature for an annotation. Fro example, a police report Annotation would have a Feature reportid, which would leverage the uniqueId() . The ultimate purpose is to send the CAS to a database table, and use the reportid as the row's unique ID.
I can't find any information on it, except here: http://uima.apache.org/d/uimaj-2.4.2/apidocs/org/apache/uima/cas/FeatureValuePath.html Contains CAS Type and Feature objects to represent a feature path of the form feature1/.../featureN. Each part that is enclosed within / is referred to as "path snippet" below. Also contains the necessary evaluation logic to yield the value of the feature path. For leaf snippets, the following "special features" are defined: coveredText() can be accessed using evaluateAsString typeName() can be accessed using evaluateAsString fsId() can be accessed using evaluateAsInt. Its result can be used to retrieve an FS from the current LowLevel-CAS. uniqueId() can be accessed using evaluateAsInt. Its result can be used to uniquely identify an FS for a document (even if the document is split over several CAS chunks) This is deprecated, and replaced with http://uima.apache.org/d/uimaj-2.4.2/apidocs/org/apache/uima/cas/FeaturePath.html However, FeaturePath does not have the uniqueID() method The feature path syntax also allows some built-in functions on the last feature path element. Built-in functions are added with a ":" followed by the function name. E.g. "/my/path:fsId()". The allowed built-in functions are: coveredText() fsId() typeName() Built-in functions are only evaluated if getValueAsString() is called. At least, I don't get it. Can I get an example? Thanks
