Method Detail

getAnnotations

public static <T extends org.apache.uima.jcas.tcas.Annotation> List<T> getAnnotations(org.apache.uima.jcas.JCas jCas,
                                                                                      org.apache.uima.jcas.tcas.Annotation windowAnnotation,
                                                                                      Class<T> cls)

This method returns all annotations (in order) that are inside a "window" annotation of a particular kind. The functionality provided is similar to using AnnotationIndex.subiterator(), however we found the use of type priorities which is documented in detail in their javadocs to be distasteful. This method does not require that type priorities be set in order to work as expected for the condition where the window annotation and the "windowed" annotation have the same size and location.

Type Parameters:

T - determines the return type of the method

Parameters:

jCas - the current jCas or view

windowAnnotation - an annotation that defines a window

cls - determines the return type of the method

Returns:

a list of annotations of type cls that are "inside" the window

getExactAnnotations

public static <T extends org.apache.uima.jcas.tcas.Annotation> List<T> getExactAnnotations(org.apache.uima.jcas.JCas jCas,
                                                                                           org.apache.uima.jcas.tcas.Annotation windowAnnotation,
                                                                                           Class<T> cls)

same as getAnnotations however boundaries for windowAnnotation and cls must exactly match!

Type Parameters:

T -

Parameters:

jCas -

windowAnnotation -

cls -

Returns:

list of annotations of type cls

hasSameOffset

public static boolean hasSameOffset(org.apache.uima.jcas.tcas.Annotation a,
                                    org.apache.uima.jcas.tcas.Annotation b)

check whether two annotation have exactly the same offset

Parameters:

a - annotation 1

b - annotation 2

Returns:

true or false
