startOffset
public int startOffset()Description copied from interface:OffsetAttribute
Returns this Token's starting offset, the position of the first character corresponding to this token in the source text.Note that the difference between
OffsetAttribute.endOffset()
andstartOffset()
may not be equal to termText.length(), as the term text may have been altered by a stemmer or some other filter.- Specified by:
startOffset
in interfaceOffsetAttribute

setOffset
public void setOffset(int startOffset, int endOffset) Description copied from interface:OffsetAttribute
Set the starting and ending offset.- Specified by:
setOffset
in interfaceOffsetAttribute
- See Also:
-
endOffset
public int endOffset()Description copied from interface:OffsetAttribute
Returns this Token's ending offset, one greater than the position of the last character corresponding to this token in the source text. The length of the token in the source text is (endOffset()
-OffsetAttribute.startOffset()
).- Specified by:
