Examples of org.apache.uima.cas.Feature

org.apache.uima.cas.Feature
The interface that describes features in the type system.
Feature short or base names are type system identifiers. The (fully) qualified name of a feature is the name of the type it is defined on, followed by a colon, followed by the its short name. For example, the qualified name of the Annotation begin feature is uima.tcas.Annotation:begin.
