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
- See Also:
OffsetAttribute.setOffset(int, int)
-
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:
OffsetAttribute.startOffset()
,OffsetAttribute.endOffset()
-
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:
endOffset
in interfaceOffsetAttribute
- See Also:
OffsetAttribute.setOffset(int, int)
-
clear
public void clear()
Description copied from class:AttributeImpl
Clears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.- Specified by:
clear
in classAttributeImpl
-
copyTo
public void copyTo(AttributeImpl target)
Description copied from class:AttributeImpl
Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.- Specified by:
