Description copied from interface:Visitable
-
hashCode
public int hashCode()Description copied from interface:Segment
Generate a hash code from thisSegment
.Hashcode typically derives from the
Segment.toString()
representation so twoSegment
s yield the sameSegment.hashCode()
if theirSegment.toString()
representation matches. -
equals
Description copied from interface:Segment
Check whether thisSegment
is equal to anotherSegment
.Equality is typically given if the
Segment.toString()
representation matches. -
toString
Description copied from interface:Segment
Return a SQL string representation of thisSegment
.The representation is intended for debugging purposes and an approximation to the generated SQL. While it might work in the context of a specific dialect, you should not assume that the
Segment.toString()
representation works across multiple databases.
