Class GTLTExpression

java.lang.Object

org.josql.expressions.GTLTExpression

public class GTLTExpression
extends BinaryExpression

This class represents one of the following:

• > - Greater than
• < - Less than
• >= - Greater than or equal to
• <= - Less than or equal to

You can also force a "string" comparison by prefixing with "$". This will force both sides to be strings via the toString method.
