getSQL

public java.lang.String getSQL()

Specified by:

getSQL in interface Expression

isLesserThan

public boolean isLesserThan(Ordered other)

Description copied from interface: Ordered

Compares the current with another object on ordering.

Specified by:

isLesserThan in interface Ordered

Parameters:

other - the object to compare to, must not be null

Returns:

true iff the current object is considered less than the one passed

isEqual

public boolean isEqual(Ordered other)

Description copied from interface: Ordered

Compare the current with another object on equality. This can be useful if a different notion of equality should be used than the one implemented by Object.equals(Object). Otherwise it should be just mapped to the latter (which in turn might map to reference identity). Note that this method does not accept null values. This also means when overriding it by mapping it to the standard equals method, a check for null should be done first.

Specified by:

isEqual in interface Ordered

Parameters:

other - the object to compare to, must not be null

Returns:

true iff the current object is considered equal to the one passed
