OffsetAttribute
.Constructor and Description |
---|
OffsetAttributeImpl()
Initialize this attribute with startOffset and endOffset of 0.
|
Modifier and Type | Method and Description |
---|---|
void |
clear()
Clears the values in this AttributeImpl and resets it to its
default value.
|
void |
copyTo(AttributeImpl target)
Copies the values from this Attribute into the passed-in
target attribute.
|
int |
endOffset()
Returns this Token's ending offset, one greater than the position of the
last character corresponding to this token in the source text.
|
boolean |
equals(Object other) |
int |
hashCode() |
void |
reflectWith(AttributeReflector reflector)
This method is for introspection of attributes, it should simply
add the key/values this attribute holds to the given
AttributeReflector . |
void |
setOffset(int startOffset,
int endOffset)
Set the starting and ending offset.
|
int |
startOffset()
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()
and startOffset()
may not be equal to termText.length(), as the term text may have been altered by a
stemmer or some other filter.

Implementations look like this (e.g. for a combined attribute implementation):
public void reflectWith(AttributeReflector reflector) { reflector.reflect(CharTermAttribute.class, "term", term()); reflector.reflect(PositionIncrementAttribute.class, "positionIncrement", getPositionIncrement()); }
If you implement this method, make sure that for each invocation, the same set of Attribute
interfaces and keys are passed to AttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object)
in the same order, but possibly
different values. So don't automatically exclude e.g. null
properties!
