Class ChainDirective
java.lang.Object
org.apache.velocity.runtime.directive.Directive
org.apache.cayenne.access.jdbc.ChainDirective
- All Implemented Interfaces:
- Cloneable, org.apache.velocity.runtime.directive.DirectiveConstants
public class ChainDirective
- extends org.apache.velocity.runtime.directive.Directive
A custom Velocity directive to conditionally join a number of chunks
.
Usage of chain is the following:
#chain(operator) - e.g. #chain(' AND ')
#chain(operator prefix) - e.g. #chain(' AND ' 'WHERE ')
