com.google.javascript.rhino.JSDocInfo

JSDoc information describing JavaScript code. JSDoc is represented as a unified object with fields for each JSDoc annotation, even though some combinations are incorrect. For instance, if a JSDoc describes an enum, it cannot have information about a return type. This implementation takes advantage of such incompatibilities to reuse fields for multiple purposes, reducing memory consumption.

Constructing {@link JSDocInfo} objects is simplified by{@link JSDocInfoBuilder} which provides early incompatibility detection.
