Class JmsGreater  

java.lang.Object
  com.presumo.jms.selector.JmsOperand

final class JmsGreater

extends JmsBinaryOperand

Expression node for the SQL greater than expression. There is no implementation for greater than equals ">=" because the parser represents such statements as a less than with the operands switched.
