FeaturePath@Deprecated public interface FeatureValuePath
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)
 FSArray, but not as the
 last path snippet. The next path snippet must contain the fully qualified type name, example:
 family/members[0]/somepackage.Person:nameIntArray, StringArray, FloatArray, but only as the last path snippet.[index] returns the array entry at index
 [last] returns the last entry of the array
 [] returns an array of values. [] is only allowed 0 or 1 time in a
 feature path. If it is used, getValueType will return one of the following:
 CAS.TYPE_NAME_STRING_ARRAY ,CAS.TYPE_NAME_INTEGER_ARRAY,CAS.TYPE_NAME_FLOAT_ARRAY.
 FSArray, an actual feature name can
 be omitted, and only the array access operator can be used. Examples:
 
 
   
        []/somepackage.Person:coveredText()
         [last]/somepackage.Person:fsId()
 
 
 
 If the feature path is defined directly, for a String, integer or float array, the array access
 operator can be used directly. Unlike FSArray, this access operator must be the only entry in the
 path.
 
 FeaturePath.getFeaturePath. Note that the client
 code needs to keep track of the "start type" of the feature path, that is, the type that contains
 the attribute used in the first snippet of the path.
 typeSystemInit of your component (CAS consumer or TAE), call
 typeSystemInit of the feature path.
 getValueType to find out whether the feature path evaluates to a String,
 and int, a float, or their array counterparts.

null if some feature within the path is not set. If the leaf
 snippet is COVERED_TEXT, returns the covered text of currentFS.currentFS - -cas - -String[] evaluateAsStringArray(int currentFS, LowLevelCAS cas)
int getFSType()
typeSystemInit has been called prior to this method.
 feature1/.../featureN-1/featureN, returns the type of
 featureN.
 feature1/.../featureN-1/typeN:featureN, returns the type
 code for typeN. (For example, if the range type of featureN-1 is FSList or FSArray)
 feature1, where feature1 is simple-valued, returns the type
 that was used in typeSystemInit
