Class ChunkDirective
java.lang.Object
org.apache.velocity.runtime.directive.Directive
org.apache.cayenne.access.jdbc.ChunkDirective
- All Implemented Interfaces:
- java.lang.Cloneable, org.apache.velocity.runtime.directive.DirectiveConstants
public class ChunkDirective
- extends org.apache.velocity.runtime.directive.Directive
A custom Velocity directive to describe a conditional chunk of a chain
.
Usage of chunk is the following:
#chunk()...#end - e.g. #chunk()A = 5#end
#chunk(condition)...#end - e.g. #chunk($a)A = $a#end
If condition is evaluated to false, chunk is not included in the chain,
if it is true, chunk is included, and if it is not the first chunk, it is
prefixed with chain join.
