Examples of RangeExpression

aQute.bnd.osgi.resource.FilterParser.RangeExpression
org.apache.hadoop.hbase.index.client.RangeExpression
Can be used to specify a range condition on a column associated with an index. When the range is non closed at one end (to specific upper bound but only lower bound) pass the corresponding bound value as null.

RangeExpression
Parse and analyze numeric range expressions. Transform them into Hibernate Criteria objects.

Legal syntax is any sequence of the following, separated by commas or semicolons:
- "10..50"
- "10.."
- "..50"
- "37"
- (empty string)
And whitespace is ignored.

The current parser allows any number of dots in place of "..". This should be construed as a bug.
