public class BetweenFilter

extends AndFilter

Filter which compares the result of a method invocation with a value for "Between" condition. We use the standard ISO/IEC 9075:1992 semantic, according to which "X between Y and Z" is equivalent to "X >= Y && X <= Z". In a case when either result of a method invocation or a value to compare are equal to null, the evaluate test yields false. This approach is equivalent to the way the NULL values are handled by SQL.
