Lucene::OffsetAttribute::toString
virtual String toString()
Returns a string representation of the object.
Lucene::OffsetAttribute::startOffset
virtual int32_t startOffset()
Returns this Token's starting offset, the position of the first character corresponding to this token...
Lucene::OffsetAttribute::endOffset
virtual int32_t endOffset()
Returns this Token's ending offset, one greater than the position of the last character corresponding...
Lucene::OffsetAttribute::setOffset
virtual void setOffset(int32_t startOffset, int32_t endOffset)
Set the starting and ending offset.
Lucene::OffsetAttribute::equals
virtual bool equals(const LuceneObjectPtr &other)
All values used for computation of hashCode() should be checked here for equality.
Lucene::OffsetAttribute::clear
virtual void clear()
Clears the values in this Attribute and resets it to its default value. If this implementation implem...

OffsetAttribute()
Lucene::OffsetAttribute::clone
virtual LuceneObjectPtr clone(const LuceneObjectPtr &other=LuceneObjectPtr())
Shallow clone. Subclasses must override this if they need to clone any members deeply.
Lucene::OffsetAttribute::copyTo
virtual void copyTo(const AttributePtr &target)
Copies the values from this Attribute into the passed-in target attribute. The target implementation ...
Lucene::OffsetAttribute::hashCode
virtual int32_t hashCode()
Subclasses must implement this method and should compute a hashCode similar to this:
